ELEUTHERODACTYLUS VENUSTUS (Gunther) 



1900. Hylodes venustus Gunther, Biologia Centrali-Americana, Reptilia and 

 Batrachia, p. 234, pi. 68, fig. C, Aug. — Nieden, 1923, Das Tierreich, Lief. 

 46, Amphibia, Anura I, pp. 409, 425. 



Type locality. — Jalapa, State of Vera Cruz, Alexico. 



Range. — Limits of range as yet undetermined. 



Remarks. — This variety was recognized as a distinct species by 

 Gunther chiefly on the account of the presence of a broad purplish 

 band from snout to vent bounded laterally on the back by converging 

 dermal ridges. These converging dermal ridges are much more widely 

 separated than on any of the specimens of E. rhodopis that are avail- 

 able for comparison. A similar color variant has been observed in 

 undoubted specimens of rhodopis. The chevronlike glandular ridge 

 over the vertebral edge of the scapula is merely the most conspicuous 

 portion of the converging dermal ridge that extends backward from 

 upper eyelid to the level of the end of the sacral diapophysis. The 

 skin of the upperparts is granular, that on the throat is smooth, and 

 that on the abdomen is granular. 



The type of E. venustus (B.M. No. 1901. 12. 19. 37) has been com- 

 pared with specimens of E. rhodopis, and it unquestionably belongs 

 in the same group as the latter. The species venustus, however,^is 

 tentatively retained until a series sufficient to determine its status is 

 available for examination. The following notes were made on the 

 type specimen: Head-and-body length, 36.9 mm.; transverse diam- 

 eter of tympanum, 2.5 mm.; transverse diameter of eye, 3.9 mm.; 

 anterior edge of eye to nostril, 3.8 mm.; the hind limb being carried
