REPTILIA. 269 



1861, p. 500), we note that he expressly states that his S. anthracinus from Mexico 

 has four upper labials and five lower, "two large and three small." The Haitian 

 examples, both ours and Boulenger's, have four above and below. This char- 

 acter also seems to be one which is very stable in this genus. 



The color described by Boulenger agrees quite well with that of our types 

 in its important features of head lines, and spots on back limbs and tail. But 

 Cope says, "Color black, the large dorsal scales tinged with blue." This colora- 

 tion which is unique among Sphaerodactyli is coupled with the different number 

 of labials mentioned in Cope's very inadequate description, and the fact that the 

 type came from Mexico, while S. picturatus comes from Haiti, a province not 

 closely related zoogeographically with Mexico, should afford sufficient reason for 

 keeping the two species distinct, and for concluding that S. anthracinus is con- 

 fined to Mexico. 



Since the above was written, I have found a single specimen, also from Haiti, 

 which Garman has identified with his species, and which I believe also is abso- 

 lutely typical in squamation. It is uniform steely gray in color, and shows that 

 Haitian specimens have a distinct dichromatism. Cope's S. anthracinus may 

 really have come from Haiti, and it may have been inaccurately described by 

 him. If, then, the species is not to be found in Mexico, and is really the same in 

 the matter of the labials, Cope's name has precedence, and this species must be 

 known as S. anthracinus. 



This species is, moreover, very closely related to S. grandisquamis Stejneger, 

 from Porto Rico. It may be distinguished by the more elongate and natter 

 snout, and by the slightly larger dorsal scales. 



Recently a Sphaerodactylus, which, as far as one may decide from a single 

 specimen, belongs to this species, has been received in exchange from the Ameri- 

 can museum of natural history in New York. It was collected in the Sierra de 

 Jalibonico in Cuba. Similar individuals were called by Gundlach (Erpet. 

 Cubana, 1880,' p. 61) S. fantasticus. I have seen specimens identified by him 

 in the "Museo Gundlach" of the Instituto de Segunda Ensahanza, in Havana. 

 While still more recently several enormous examples have been collected by Mr. 

 W. M. Mann at Diquini, Haiti.
