THE HERPETOLOGY OF HISPANIOLA

lower surfaces of the limbs. In proportions the species is very stable. 

 The shovel is sUghtly more developed in some cases than in others, 

 while the head may often be broader in relation to its length than in 

 the described specimen. The small glands below and behind the ear 

 are usually quite prominent and are often distinctly yellowish in color, 

 in sharp contrast to the semicircular black ear-patch that limits their 

 upper border. 



The species attains a comparatively large size, our largest specimens 

 (U.S.N.M. Nos. 65712 and 65714) totaling 53 mm. from snout to vent. 



Relationships. — Dr. Noble indicates the relationship of this species 

 to Eleutherodadylus inoptatus, and the one suggests the other in many 

 respects while differing in some details. The habitus of both is more 

 Leptodactylus-]ike than is the case in most other members of the large 

 genus Eleutherodadylus. In essential color pattern, in the presence 

 of a dorsolateral fold and a subsidiary diagonal row of glands on the 

 sides, and in the relative proportions of the toes the two species are 

 similar. But the absence of a tubercle on the eyelid and the presence 

 of the conspicuous shovel on the snout, as well as its much smaller 

 adult size, distinguish ruthae readily enough from its large relative.

Diagnosis. — Toes without distinct dermal margins; tongue ovoidal, 

 not nicked posteriorly; tympanum equals width of eye; vomerine teeth 

 in two exceedingly heavy, slightly curved series, almost meeting in the 

 center behind the choanae and extending laterally beyond the choanae 

 about one-third their own length; snout short, projecting at the tip, 

 depressed, without a distinctly sharp edge; hindlegs extremely short.
