220 BARBOUR: ZOOGEOGRAPHY. 



The case of this species is quite different from the others. Still it seems 

 wisest to consider it here instead of in the list of certainly authenticated species. 



Gymnophthalmus Iuetkenii Bocourt. 

 Bocourt, Miss. sci. Mex. Reptil., 1881, p. 474. Boulenger, Cat. lizards Brit, mus., 1885, 2, p. 429. 



The type of the species was said to have been collected on St. Lucia by 

 Bonnecourt, who sent a single specimen to the Paris museum. The specimens 

 of this genus from St. Lucia reported by Garman and Boulenger all belong to 

 G. pleii, so that it is probable that the locality of this type is incorrect. Never- 

 theless, the evident close relationship between the two species suggests that G. 

 Iuetkenii will eventually be found on some other of the Lesser Antilles, unless 

 indeed it exists in St. Lucia alongside of its congener. In this case, it must be 

 very rare to have escaped capture by so excellent a collector as Garman. 



In 1860 Cope described Scolecophis fumiceps (Proc. Acad. nat. sci. Phila., 

 1860, p. 371) stating that the type was in the Museum of Comparative Zoology 

 and that it probably came from Cuba. It probably did not come from Cuba, 

 and I cannot find that the specimen which Cope borrowed was returned. Bou- 

 lenger considers Cope's new species a synonym of Homolocranium planiceps, (cf. 

 Cat. snakes Brit, mus., 1896, 3, p. 226). 



Ameiva bifrontata Cope. 

 Cope, Proc. Acad. nat. sci. Phila., 1862, p. 67. 



This species was described from St. Thomas. It is confined to the mainland 

 of South America. 1 The type locality was the result of an error in labeling. 



INTRODUCED SPECIES. (FORTUITOUSLY OR OTHERWISE). 



Bufo marinis (Linne). 

 Linne, Syst. nat., ed. 10, 1758, p. 211. Boulenger, Cat. Batr. Sal. Brit, mus., 1882, p. 315. 



A South American species which has been carried purposely to almost all the 

 Antilles. We have it from Grenada, Barbados, St. Lucia, St. Kitts, Martinique, 

 Nevis, Montserrat, and Jamaica, as well as from the Bermudas. 



■The status of this species has just been fixed by Ruthven (Occas. papers, Univ. Mich, mus., 

 Dec. 27, 1913, no. 2, p. 1-3).
