REPTILIA. 293 



The species is confined to Cuba and the following notes will serve to make 

 more clear its relationships. 



It is closely related to A. homolechis, and has similar habits. It may be 

 recognized at once in the field by its enormously developed gular sac, which in A. 

 homolechis is pale white, while in this species it is carmine in the centre with a 

 broad marginal band of brilliant yellow. Besides this, it may be distinguished 

 by having fewer scales between the occipital shield and the superciliaries, and in 

 having the scales which surround the occipital for some distance upon the upper 

 temporal regions of a much smaller size. The canthus rostralis is separated from 

 the frontal ridge by two or three rows of scales. 



.Altogether this species is very similar to A. homolechis in details of squama- 

 tion. Without examining the type of A. homolechis, which is, according to Cope, 

 in the British museum without locality, it is impossible to be perfectly sure that 

 the species which I am naming now is not A . homolechis itself and the one with 

 the white dewlap a new species. Cope's description is ambiguous, and the two 

 forms with which I am dealing are obviously ^'ariable in many characters. 

 Nevertheless, the dewlap color, which I have learned to regard as a very excellent 

 one, di\ides them sharph^ into two groups. Cope mentions the dewlaps as being 

 large. It is rather large in homolechis, but much larger in angusticeps. How- 

 ever, his note of the canthus as separated from the frontal ridge by but one row 

 of scales, of the occipital as separated from the superciliaries by many rows of 

 scales, and by his mention of the metallic shades of the ventral surface would 

 seem to fasten the name homolechis to the group of individuals having the white 

 dewlap. This conclusion was reached last year by Dr. Stejneger and myself 

 before I had this related form. That we are dealing with two distinct forms I 

 have no doubt; but without an adequate description or a re-examination of the 

 type, there is no use attempting to do more than call attention to the facts, and 

 leave a more detailed discussion of status until the original type of homolechis 

 can be examined.

This extremely distinct species, which was figured by Cocteau in Sagra's 

 Historia de Cuba, Reptiles, pi. 9, is confined to Cuba. It has very frequently 

 been confounded with the North American A. carolinensis and the Bahaman 

 ^4. hrunneus. Even Boulenger, in the Catalogue of lizards, 1885, 2, p. 43, in- 

 cluded it in the synonymy of A . carolinensis.
