Genus GYMNOPHTHALMUS Merrem 



GYMNOPHTHALMUS LAEVICAUDUS (Cope) 



1870. TreUoscinus laevicaudus Cope, Proc. Amer. Philos. Soc, vol. 11, p. 557 



(type locality, Occidental Department, Nicaragua). 

 1876. Eimplielus sumichrastU Cope, Journ. Acad. Nat. Sci. Philadelphia, ser. 



2, vol. 8, p. 115 (type locality, Costa Rica). 

 1885. Gijmnophthahnus siimichrasii Bocoukt, Miss. Sci. Mexique et Amer. Cent., 



Kept., p. 471, pi. 20 H, fig. 2. — Boxilenger, Cat. Liz. Brit. Mus., vol. 2, p. 



428. — RuTHVEN, Misc. Publ. Mus. Zool. Univ. Michigan, no. 8, 1922, 



p. 64. 

 1885. Tretioscincus laevicauda Boxilenger, Cat. Liz. Brit. Mus., vol. 2, p. 426. 

 1887. Gymnophthalinus laevicaudus Cope, Bull. U. S. Nat. Mus., no. 32, p. 46. 



As shown by Cope (1887), his Gymnophthalmus sumichrastU and 

 his Tretioscincus laevicauda, which were recognized as distinct from 

 each other by Boulenger, 1885, and certain later writers, are one 

 and the same species. Cope's error in making the original generic 

 diagnosis of laevicaudus and his subsequent failure to describe its 

 true generic characters no doubt led Boulenger (1885) to retain 

 laevicaudus as a form of Tretioscincus instead of referring it to the 

 genus Gymnophthahnus. 



A specimen of laevicaudus, U.S.N.M. No. 72755, collected at San 

 Juan de los Morros, Aragua, Venezuela, by H. Pittier may be de-
