2 ON THE WEST INDIAN TEIIDiE 



Centroptx Copii, nom. sp. n. 



Barbadoes. 



"Back with three pale lines; dorsal scales, minute. 

 Surinam, Mus. Leyd." is the original announcement, of 

 his species C entropy x intermedins (Schleg.), by Dr. Gray, 

 1831, Syn. Kept., 31 (in Griff. Cuv. An. King., ix). 

 In his Catalogue of Lizards B. M., 1845, he says O. in- 

 termedins is synonymous with C calcaratus. 



Professor Cope, 1861, Pr. Phil. Ac, 496, is the first 

 to give a description which unquestionably applies to the 

 Centropyx of Barbadoes. Whether Dr. Gray was right in 

 his later conclusion in regard to what he had called C. 

 intermedins, it is evident he was not acquainted with the 

 Barbadan type. Hence it would appear preferable that 

 the latter should bear the name of the distinguished nat- 

 uralist who first made it known.
