Rejytiles and Frogs from Donmiica. 363 



Thecadactylus rapicauda (Houtt.). 



Two specimens, from Laudat and Laion. Generally dis- 

 tributed in the neotropical region. 



Sphcerodactylus Copii (Steind.). 



Three specimens from Laion agree in the technical cha- 

 racters with this obscure species. 



Ameiva fuscata. 



Ameiva fuscata, Garman, Bull. Ess. Inst. xix. 1887, p. 5. 



Closely allied to A. surinamensis ; the Dominica form may 

 be kept distinct on account of the modified scutellation of the 

 fore and hind feet. The large scutes of the forearm are 

 separated from the rows of scute] la of the toes by broad areas 

 of very minute scales. 



Anolis alliaceus.

 Anolis Leachii, part., Boul, Lizards, ii. p. 29. 



Sixteen specimens of both sexes and all sizes. 



Mr. Boulenger has not without reason referred the Domiu- 

 ica Anolis to A. Leachii. However, Dominica specimens 

 can be recognized at a glance, on account of their extremely 

 minute scutellation, resembling in this, as well as the other 

 points, specimens from Montserrat and Saba, and differing 

 widely from those from Guadeloupe [Xiphosurus ferreus^ Cope, 

 =^ Anolis Leachii^ D. B., Bocourt). The difference in the 

 size of the scales is conspicuous on every part of the head 

 and body, and particularly on the temple. However, it must 

 be admitted that some specimens in the Museum, for instance 

 the type of Gray's Anolis reticulatus^ whose origin is not 

 known, are intermediate between the small- and large-scaled 

 forms. 



Having the type of Anolis alliaceus in the Museum, and 

 having received from the museum at Harvard College speci- 

 mens of Cope's A. oculatus and Garman's A. lividus and^. 

 sahaniis, I cannot entertain any doubt as to their identity.
