Anolis marmoratus Dumeril et Bibron.

Having no Guadeloupe specimens, I am unable to test the question of the 

 distinctness of this species from A. leachii. Boulenger (Cat. lizards, Brit, mus., 

 1885, 2, p. 31) says: — "I am not able to detect in the description a single char- 

 acter of sufficient importance to justify a separation of this form from A. leachii." 

 Since that was written Gunther has admitted A. alliaceus Cope from Dominica 

 to be different from A. leachii; and it would be very strange to find the same 

 lizard upon Guadeloupe and Martinique, and a different one upon Dominica. 

 So that, upon this inferential evidence alone, there is but little doubt as to the 

 validity of the species. Garman has identified a large series from the island 

 of Desirade as belonging here; they should, however, also be compared with 

 specimens from Martinique. 



Anolis bimaculatus (Sparrman). 



Sparrman, K. vet. akad. Handl., 1784, 5, p. 179, pi. 4, fig. 4. Garman, Bull. Essex inst., 1887, 19, 

 p. 29. 



With this ancient and much disputed species Garman has identified speci- 

 mens from St. Kitts and Nevis. This seems an excellent solution of the question. 

 There can be no doubt of the distinctness of lizards of these islands from those 

 of Guadeloupe (A. leachii) and Dominica (A. alliaceus) with which this species 

 was associated by Boulenger (Cat. lizards Brit, mus., 1885, 2, p. 29), who in- 

 cluded it in part with what he called Anolis alligator, another composite species. 

 In a recent letter, Dr. Stejneger calls my attention to what Andersson has to 

 say regarding this species (Bihang. Svensk vet.-akad. Handl., 1900, 26, 4, 1, 

 p. 27). He has the types from St. Eustatius in hand, and believes that the 

 name should replace A. leachii; but the species are better kept apart until 

 examples from Guadeloupe can be compared with others from these three islands. 



Anolis richardii Dumeril et Bibron.

In spite of the direct statement of O'Shaughnessy (Ann. mag. nat. hist., 1875, 

 ser. 4, 15, p. 275), that Gray's A. occipitalis and A. stenodactylus belong to this 

 species, which Dumeril and Bibron described from the island of Tortola, we can 

 but emphasize the enormous discrepancies between the descriptions of all these 

 species. Boulenger has followed O'Shaughnessy; but by examining the list of 

 specimens in the British museum given by Boulenger, it may be observed that
