320 BARBOUR: ZOOGEOGRAPHY. 



Mabuya spilonota Wiegmann. 



WiEGMANN, Arch. f. natiirg., 1837, p. 135. 



This Jamaican species should bear this name, as has been shown by Stejneger, 



who agrees with Garman as to its vahdity. (Stejneger, Rept. U. S. nat. mus. for 



1902, 1904, p. 608). This is the species of which I (Bull. M. C. Z., 1910, 52, 



p. 299) gave a short account regarding its habits, abundance, and distribution, 



unfortunately using the name M. sloanii, inadvertently following Garman instead 



of Stejneger, although the latter is obviously correct in the application of these 



names. 



Mabuya sloanii (Daudin). 



Daudin, Hist. nat. rept., 1803, 4, p. 287, pi. .5.5, fig. 2. Stejneger, Rept. U. S. nat. mus. for 1902, 1904, 

 p. 608, fig. 56-58. 



Stejneger (loc. cit.) has given excellent reasons for using this name for the 

 Porto Rican Mabuya, and also for considering this form distinct from that 

 upon Jamaica. This species, in common with its other generic relatives, is 

 one of the very first species to succumb to the ravages of the mongoose. In 

 Porto Rico it was so rare that Stejneger and the other naturaUsts with him did 

 not find a single example. This has been the experience of many other collectors 

 upon other islands. A regrettable fact since large series of specimens are particu- 

 larly desu-able to settle definitely the many questions regarding variation within 

 the species of these variable forms, and to determine how distinct the various 

 insular races really are. 



The range of Mabuya sloanii comprises the islands of Vieques, Porto Rico, 

 Mona, St. Thomas, St. John, Just van Dyke, St. Croix, and besides this the 

 limited material indicates that Haitian specimens should be referred to the 

 same species. 



Mabuya mabouia DuMfiRiL et Bibron. 

 Du.MERiL ct Bibron, Erpet. gen., 1839, 5, ji. 646. Garman, Bull. Essex inst., 1887, 19, p. 52. 



The specimens in the Museum are from Martinique. The describers state 

 that they have received it also from Guadeloupe. It is not probable, however, 

 that the seines upon these two islands should be aUke, and those upon Dominica 

 different, when the latter island lies exactly between them. 



Mabuya lanceolata Cope. 

 Cope, Proc. Acad. nat. sci. Phila., 1862, p. 187. 



This species was based upon Barbadian specimens collected by Theodore 

 Gill. I have seen no specimens and cannot conuuent upon the validity of the 

 species.
