332 BATRAOHIANS AND LAND REPTILES 



their exact systematic and geographical limits are as vet not very clearly made 

 ont. In the Bahamas the species thus far has been fonnd only on Enm Cay. 



Mabuya sloanii (Daudin) (?). 

 Scincus sloanii Daudin, 1803, Hist. Nat. Rept., vol. iv, p. 287. 



Cope is the only author to record a skink from the Bahamas. It was 

 brought from Turks Islands by Professor Adrian J. Ebell and was first enu- 

 merated by Cope as M. cepedei, but afterwards as M. agilis. This name be- 

 longs to a South American species, however, and undoubtedly is inapplicable 

 to the Turks Islands slippery-back. As I have not seen the specimen I can 

 not be absolutely certain of its identity, but Wie chances are that it is M. sloanii 

 which occurs in Haiti and Porto Eico. 



Ameiva thoracica Cope. 

 Ameiva thoracica Cope, 1862, Proc. Acad. Nat. Sci. Phila., p. 64. 

 Most nearly related to the Cuban ^4. aubcri Cope. 



Ameiva maynardii Garman. 



Ameiva maynardii Garman, 1888, Bull. Essex Inst., vol. xx, p. 10. 



This, on the other hand, belongs to a different section of the genus which 

 is only represented in Haiti and the island of St. Croix. 



Anolis porcatus Gray. 

 Anolis porcatus Gray, 1840, Ann. Mag. Nat. Hist., p. 112. 



As has been shown long ago by Garman, there are very good reasons for 

 separating the Cuban form under the above name from Anolis carolinensis 

 Dumeril and Bibron of the southern United States. The Bahama specimens 

 are very close to the Cuban ones, though I have a strong suspicion that even- 

 tually they may be found to be separable. So much is certain, however, that 

 the Bahama form is in no way directly connected with A. carolinensis, but 

 that its relationship is with Gray's A. porcatus. Whether Cope's A. porcatus 

 hrunneus, from Crooked Island, is a really distinguishable local form must 

 remain undecided for the present because of lack of material.
