BARBOUR: NOTES ON THE HERPETOLOGY OF JAMAICA. 289 



harsh grating snoring of this frog is heard all over the island where wild pines are 

 abundant, i. e. at a slight elevation above sea level. 



As with so many other West Indian forms, it becomes more and more certain, as 

 extensive collections from the different islands are studied, that their distribution 

 is not so wide-spread as many of the older writers have supposed. Neither do 

 many closely related forms generally exist on one island. This very fact now so 

 well proven rendered the record of three closely related Hylas from Jamaica as 

 obviously suspicious ; and these three species typical of other islands reduce them- 

 selves to one peculiar form. It may be noted here that the citation given by 

 Boulenger to the original description of Hyla dominicensis Tschudi (Batr., 1838, 

 p. 72) refers to a nomen nudum. The description is on page 30. 



Hyla lichenata (Gosse). 



Trachycephalus lichenatus Gosse, Nat. Sojourn in Jamaica, 1851, p. 362, pi. 7. 



Unfortunately I have been unable to examine a single specimen of this most 

 strange creature. Neither this Museum nor the United States National Museum 

 has a single example, and I have learned recently that the specimens which Cope 

 reported were in the Museum of Amherst College have been discarded as too 

 poorly preserved. Cope also recorded (Proc. Acad. Nat. Sci., Phila., 1S63, p. 

 46-47) a specimen in the Smithsonian Collection, which has been lost. The 

 species Hyla atwcklorus (Gosse), redescribed by Cope (loc. cit.), was doubtless 

 based on sexual characters of divergence only. 



The, species, which seems very rare, is known from Jamaica only. 



Gonatodes albogularis (Dum. & Bibr.). 



Boulenger, Cat. Lizards Brit. Mus., 1885, 1, p. 59. 



Gymnodactylus albogularis Dumeril et Bibron, Erp. Gen., 3, 1836, p. 415. 



I have three specimens from Kingston, kindly sent me by Dr. Boulenger, who 

 writes that Mr. C A. Wray recently took a number in wooden houses about that 

 town. The species must be of very local distribution, as none of the collections 

 accessible contain specimens. The British Museum had two Jamaican speci- 

 mens when the catalogue was compiled. Dr. Duerden remarked that it was very 

 rare and that the Museum of the Institute of Jamaica had never received a single 

 example. 



Occurs in Cuba and Jamaica ; like other geckos, it may prove to be of wider 

 fortuitous distribution. Perhaps, we might almost say probably, introduced into 

 Kingston by the direct communication with Santiago de Cuba. 



Aristelliger praesignis (Hallowell). 



Hemidactylus praesiynis Hallowell Proc. Acad. Nat. Sci. Phila., 1856, p. 222. 



Another species which is generally wide-spread over the island. The natives 

 have a peculiar fear of " the croaking lizard," and it is seldom that they can be 

 persuaded to bring it in. Mr. Wight notes that it seems to be rare. This,
