the M. C. Z. from St. Croix. All belong to the same species ; the Anegada 

 specimens are much paler, more ashy, than any of the others, and the 

 variation observable in this large number of individuals shows that S. 

 grandisquamis Stejneger, from Porto Rico, distinguished by the larger 

 size of the dorsal scales is really far from conspicuously distinct. The 

 species may perhaps stand, however, since there is no doubt but that the 

 average numbers of scales upon the dorsal area is slightly fewer. 



Ameiva exul (Cope). 



Peters got ground lizards as follows: 1 from Ginger Island nearTortola, 

 3 from Tortola, 2 from Mosquito Island near Virgin Gorda, 9 from Virgin 

 Gorda, 13 from Anegada, and 8 from Water Island near St. Thomas. 

 Although this series varies somewhat in coloration from island to island, 

 I believe that beyond doubt all these lots represent the same species. To 

 my disappointment no Ameiva of the polops-wetmorei series turned up. 

 Ameivseof this group are excessively rare everywhere, perhaps just disap- 

 pearing; they may have completely gone in these islands. 



Anolis cristatellus Dumeril and Bibron. 



Peters found this lizard common everywhere, and he secured specimens 

 upon St. Thomas, Anegada, Tortola, Virgin Gorda, Water Island, and 

 Mosquito Island near Virgin Gorda. These have been compared with 

 each other and with specimens in the M. C. Z. from Porto Rico and St. 

 Croix. The species is variable, but I believe the same form inhabits all 

 these different islands. Reinhardt and Liitken (Vid. Meddel. Naturh. 

 Foren., 1862 (1863), p. 249), in their most excellent paper record crista- 

 tellus from St. Thomas, St. John, St. Croix, Jost van Dyke, Water Island, 

 Tortola, Vieques, and Porto Rico. 



Anolis stratulus Cope. 



Reinhardt and Liitken (1. c, p. 255) record this species from St. Thomas, 

 Porto Rico, Vieques, Tortola, and Jost van Dyke. Peters found a single 

 example upon Tortola, while Garman got two, years ago, upon St. 

 Thomas, during the Blake cruise. These three seem the same as other 

 examples before me from Porto Rico and Vieques. 



Anolis pulchellus Dumeril and Bibron. 



Specimens which have been compared with examples of pulchellus 

 from St. Thomas and Porto Rico were taken by Peters upon Virgin 

 Gorda, Tortola, and Anegada. Of these three islands Reinhardt and 

 Liitken had the species from Tortola alone. Peters believes that beyond 

 doubt this and the preceding two species are the only Anoles found upon 

 any of these islands. No sign of A. krugi was found, though Stejneger 

 thought (Herp. of Porto Rico, 1902 (1904), p. 659) that possibly krugi 

 might occur in the highlands of some of the islands of the Virgin group. 



Dumeril and Bibron (Erp. Gen., 4, 1841, p. 141) described A. richardii, 

 expressly stating that the type was a single example taken on Tortola by
