Tanti, 2000 feet. A single {^) specimen. 



This small frog is closely allied to P. ingm'nah's, Co'pe, hitherto 

 the unique species of the interesting genus Prostherapis, Cope. 

 The British Museum having recently received the latter from 

 Ecuador (Sarayacu and Canelos) through Mr. Buckley, I have 

 been able to compare it with this new form ; and I have no doubt 

 they are perfectly distinct from each other. In P. inguinalis tiie 

 tympanum is hidden, the first finger is longer than the second, 

 the digital expansions are larger, there is an outer metatarsal 

 tubercle, and the upper lip is margined with white.

 Two specimens from Tanti.

 Quito (9500 feet) ; one young from Placienda of Guachala 

 (9200 feet) ; and an adult from Uiobamba (9000 feet). 



Of this frog, Mr. A\Miymper says it " is one of the most
