e talking about。〃
〃But Tina specifically said the neck was long；〃 Ellen Bowman insisted。 〃And she said there were three toes on the foot。〃
〃Tina's pretty observant；〃 Mike Bowman said。
〃I'm sure she is；〃 Guitierrez said； smiling。 〃But I still think your daughter was bitten by a mon basilisk amoratus； and had a severe herpetological reaction。 Normal time course with medication is twelve hours。 She should be just fine in the morning。〃
In the modern laboratory in the basement of the Clínica Santa Maria； word was received that Dr。 Guitierrez had identified the animal that had bitten the American child as a harmless basilisk lizard。 Immediately the analysis of the saliva was halted； even though a preliminary fractionation showed several extremely high molecular weight proteins of unknown biological activity。 But the night technician was busy； and he placed the saliva samples on the holding shelf of the refrigerator。
The next morning； the day clerk checked the holding shelf against the names of discharged patients。 Seeing that BOWMAN； CHRISTINA L。 was scheduled for discharge that morning； the clerk threw out the saliva samples。 At the last moment； he noticed that one sample had the red tag which meant that it was to be forwarded to the university lab in San José。 He retrieved the test tube from the wastebasket； and sent it on its way。
〃Go on。 Say thank you to Dr。 Cruz；〃 Ellen Bowman said； and pushed Tina forward。
〃Thank you； Dr。 Cruz；〃 Tina said。 〃I feel much better now。〃 She reached up and shook the doctor's band。 Then she said； 〃You have a different shirt。〃
For a moment Dr。 Cruz looked perplexed； then he smiled。 〃That's right； Tina。 When I work all night at the hospital； in the morning I change my shirt。〃
〃But not your tie？〃
〃No。 Just my shirt。〃
Ellen Bowman said； 〃Mike told you she's observant。〃
〃She certainly is。〃 Dr。 Cruz smiled and shook the little girl's band gravely。 〃Enjoy the rest of your holiday in Costa Rica； Tina。〃
〃I will。〃
The Bowman family had started to leave when Dr。 Cruz said； 〃Ob； Tina； do you remember the lizard that bit you？〃
〃Uh…huh。〃
〃You remember its feet？〃
〃Uh…huh。〃
〃Did it have any toes？〃
〃Yes。〃
〃How many toes did it have？〃
〃Three；〃 she said。
〃How do you know that？〃
〃Because I looked；〃 she said。 〃Anyway； all the birds on the beach made marks in the sand with three toes； like this。〃 She held up her hand； middle three fingers spread wide。 〃And the lizard made those kind of marks in the sand； too。〃
〃The lizard made marks like a bird？〃
〃Uh…huh；〃 Tina said。 〃He walked like a bird； too。 He jerked his head like this； up and down。〃 She took a few steps； bobbing her head。
After the Bowmans had departed； Dr。 Cruz decided to report this conversation to Guitierrez； at the biological station。
〃I must admit the girl's story is puzzling；〃 Guitierrez said。 〃I have been doing some checking myself。 I am no longer certain she was bitten by a basilisk。 Not certain at all。〃
〃Then what could it be？〃
〃Well；〃 Guitierrez said； 〃let's not speculate prematurely。 By the way； have you heard of any other lizard bites at the hospital？〃
〃No； why？〃
〃Let me know； my friend； if you do。〃
The Beach
Marty Guitierrez sat on the beach and watched the afternoon sun fall lower in the sky； until it sparkled harshly on the water of the bay； and its rays reached beneath the palm trees； to where he sat among the mangroves； on the beach of Cabo Blanco。 As best he could determine； he was sitting near the spot where the American girl had been； two days before。
Although it was true enough； as he had told the Bowmans； that lizard bites were mon； Guitierrez had never heard of a basilisk lizard biting anyone。 And he had certainly never heard of anyone being hospitalized for a lizard bite。 Then； too； the bite radius on Tina's arm appeared slightly too large for a basilisk。 When he got back to the Carara station； he had checked the small research library there； but found no reference to basilisk lizard bites。 Next he checked International BioSciences Services； a puter database in America； But he found no references to basilisk bites； or hospitalization for lizard bites。
He then called the medical officer in Amaloya； who confirmed that a nine…day…old infant； sleeping in its crib； had been bitten on the foot by an animal the grandmother…the only person actually to see it…claimed was a lizard。 Subsequently the foot had bee swollen and the infant had nearly died。 The grandmother described the lizard as green with brown stripes。 It had bitten the child several times before the woman frightened it away。
〃Strange；〃 Guitierrez had said。
〃No； like all the others；〃 the medical officer replied； adding that he had heard of other biting incidents： A child in Vásquez； the next village up the coast； had been bitten while sleeping。 And another in Puerta Sotrero。 All these incidents had occurred in the last two months。 All had involved sleeping children and infants。
Such a new and distinctive pattern led Guitierrez to suspect the presence of a previously unknown species of lizard。 This was particularly likely to happen in Costa Rica。 Only seventy…five miles wide at its narrowest point； the country was smaller than the state of Maine。 Yet； within its limited space； Costa Rica had a remarkable diversity of biological habitats： seacoasts on both the Atlantic and the Pacific； four separate mountain ranges； including twelve…thousand…foot peaks and active volcanoes； rain forests； cloud forests； temperate zones； swampy marshes； and arid deserts。 Such ecological diversity sustained an astonishing diversity of plant and animal life。 Costa Rica had three times as many species of birds as all of North America。 More than a thousand species of orchids。 More than five thousand species of insects。
New species were being discovered all the time at a pace that had increased in recent years； for a sad reason。 Costa Rica was being deforested； and as jungle species lost their habitats； they moved to other areas； and sometimes changed behavior as well。
So a new species was perfectly possible。 But along with the excitement of a new species was the worrisome possibility of new diseases。 Lizards carried viral diseases； including several that could be transmitted to man。 The most serious was central saurian encephalitis； or CSE； which caused a form of sleeping sickness in human beings and horses。 Guitierrez felt it was important to find this new lizard； if only to test it for disease。
Sitting on the beach； he watched the sun drop lower； and sighed。 Perhaps Tina Bowman had seen a new animal； and perhaps not。 Certainly Guitierrez had not。 Earlier that morning； he had taken the air pistol； loaded the clip with ligamine darts； and set out for the beach with high hopes。 But the day was wasted。 Soon he would have to begin the drive back up the hill from the beach； he did not want to drive that road in darkness。
Guitierrez got to his feet and started back up the beach。 Farther along； he saw the dark shape of a howler monkey； ambling along the edge of the mangrove swamp。 Guitierrez moved away； stepping out toward the water。 If there was one howler； there would probably be others in the trees overhead； arid howlers tended to urinate on intruders。
But this particular howler monkey seemed to be alone； and walking slowly； and pausing frequently to sit on its haunches。 The monkey had something in its mouth。 As Guitierrez came closer； he saw it was eating a lizard。 The tail and the hind legs drooped from the monkey's jaws。 Even from a distance； Guitierrez could see the brown stripes against the green。
Guitierrez dropped to the ground and aimed the pistol。 The howler monkey； accustomed to living in a protected reserve； stared curiously。 He did not run away； even when the first dart whined harmlessly past him。 When the second dart struck deep in the thigh； the howler shrieked in anger and surprise； dropping the remains of its meal as it fled into the jungle。
Guitierrez got to his feet and walked forward。 He wasn't worried about the monkey； the tranquilizer dose was too small to give it anything but a few minutes of dizziness。 Already he was thinking of what to do with his new find。 Guitierrez himself would write the preliminary report； but the remains would have to be sent back to the United States for final positive identification； of course。 To whom should he send it？ The acknowledged expert was Edward H。 Simpson； emeritus professor of zoology at Columbia University； in New York。 An elegant older man with swept…back white hair； Simpson was the world's leading authority on lizard taxonomy。 Probably； Marty thought； he would send his lizard to Dr。 Simpson。
New York
Dr。 Richard Stone； head of the Tropical Diseases Laboratory of Columbia University Medical Center； often remarked that the name conjured up a grander place than it actually was。 In the early twentieth century； when the laboratory occupied the entire fourth floor of the Biomedical Research Building； crews of technicians worked to eliminate the scourges of yellow fever； malaria； and cholera。 But medical successes…and research laboratories in Nairobi
