stantly. Two metatarsal tubercles were present in the type; in the 

 frogs from the Dominican Republic the outer tubercle is absent or so 

 weak that it can scarcely be distinguished in all but two specimens, 

 in which it is quite apparent. The type had the skin smooth in the 

 middorsal area, but my specimens are more usually glandular and 

 ridged, only one example failing to show at least a trace of these 

 ridges. A large series from Diquini and neighboring points in Haiti 

 must be collected and studied before it will be possible to tell whether 

 the form from the Dominican Republic deserves a new specific name. 



Relationships. — This singular species seems to have but one close 

 relative in the West Indies, Eleutkerodactylus ruthae, described by 

 Noble nine years after the description of inoptatus. A discussion of 

 their relationships appears on p. 33. Dr. Barbour remarks that his 

 E. inoptatus superficially resembles E. insignitus from the Santa 

 Marta Mountains of Colombia. 



The young of inoptatus is strikingly similar to the adult of E. ruthae, 

 differing mainly in its snout, which does not project much beyond the 

 front of the lower jaw in the former, and in the presence of the tubercle 

 on the heel.
