10S Mr. J. E. Gray on Reptiles

The shell of this species is more attenuate than the last, 

 and the mouth and beak longer and much narrower ; seven 

 strong ribs proceed from base to apex in the manner of those 

 on Pleurotoma sept angular is, to which it is nearly allied, but 

 differs, besides form, in being spirally striated: it is nearly as 

 strong. Its colour is dusky white, with obscure rufous spiral 

 bands. Several specimens were dredged at the same time 

 and place with the last.

Possibly a Lottia. A shell so nearly resembling an Ancy- 

 lus, that had I not dredged it, I should have looked on it as 

 such. The apex is more incurved than in any of our other 

 species of smaller Patellce, and the shell much more conical. 

 It was dredged along with the two last described species in 

 Lamlash Bay, Arran. 



XIII. — Catalogue of the Species of Reptiles collected in Cuba 

 by W. S. MacLeay, Esq. ; — with some Notes of their Habits 

 extracted from his MS. By J. E. Gray, Esq., F.R.S. 



The Catalogue is a continuation of the former one of Mam- 

 malia from the same island, published in a former Number of 

 this work, vol. iv. p. 1. 



It is w r orthy of remark that all the species described in the 

 former paper are different from any mentioned in the Fauna 

 of Cuba now in course of publication by M. Sagra. Several 

 of the reptiles contained in this list appear to have been also 

 found by that naturalist ; but others which have been brought 

 home by Mr. MacLeay we have reason to think have escaped 

 his research. 



As the species of the genus Anolis are difficult to distinguish, 

 and as there are several species in the British Museum which 

 I cannot refer with any certainty to the species described by
