of skin between the thighs posteriorly, the granules apparently 

 occurring also in the skin of the belly. 



"Dimensions. — Tip of snout to vent, 35 mm.; width of head, 15 

 mm.; tip of snout to posterior border of tympanum, 12 mm.; diameter 

 of eye, 4 mm.; diameter of tympanum 2.5 mm.; foreleg from axilla, 

 21 mm.; hindleg from vent, 53 mm.; vent to heel, 32 mm. 



"Color (in alcohol). — The ground color has badly bleached and 

 altered, due to poor preservation, and appears now as a pale olive- 

 buff. The color pattern is very distinct, however, and is unlike that 

 of any other known Eleutherodaciylus from Hispaniola. A broad pale 

 band between the eyes is emphasized posteriorly by a narrow brown 

 irregular line caused by the grouping of small brown dots which thickly 

 cover the upper anterior parts of the body, the snout and forelegs, 

 less thickly on the posterior parts and hindlegs. The back of the 

 thighs is strongly marked by very characteristic coarsely-reticulated 

 dark brown blotches on a very light background. A few similar 

 blotches appear on the front of the thigh and on the sides near the 

 groin. The entire lower surface appears to be immaculate olive-buff. 

 The sides of the snout and head are thickly peppered with small brown 

 dots which are not arranged in any definite pattern. 



"Variation. — There are three other specimens of this species (U.S. 

 N.M. Nos. 72618-20) with the same data as the type, but in even 

 poorer condition. They all show the perfectly distinctive dark 

 blotches on the back of the thigh and in the region of the groin. One 

 of these, 72619, shows a brown semicircular line bordering the upper 

 part of the tympanum on what appears to be a faint glandular ridge. 

 The interocular light band may also be plainly seen on this frog. The 

 other two specimens are devoid of head markings. 



"In 72620, a small individual somewhat less shriveled than the type, 

 the disk of the third finger very nearly covers the tympanum. In 

 72619 only is the granulation of the belly skin very apparent, the 

 other specimens having suffered considerably in the mutilation of 

 this part of the body. On none of the paratypes can any longitudinal 

 glands or dorsolateral folds be made out, this species evidently being 

 of the smoother skinned ones. The paratypes are all smaller than 

 the type, measuring respectively 28, 29 and 32 mm. from snout to 

 vent." 



In a series of frogs from Moron evidently referable to this species, 

 a uniform light color is prevalent. Slight traces of a web between 

 the toes are to be seen in some examples. The outline of the snout 

 viewed from above appears less pointed in some individuals than in 

 others. 



Relationships. — This form is closely related to E. auriculatoides, 

 being obviously of the same stock as the Cuban auriculatus. It 

 differs from auriculatoides in having a slightly longer eye and a longer
