PROSTHERAPIS WHYMPEHI, BOULENGER. 

 TANTI, 1890 FEET. 



This small frog is closely allied to P. inyuinalis, Cope, hitherto the uni([Ue 

 species of the interesting genus Prosthercqns, Cope. The British Museum 

 having recently received the latter from Ecuador (Sarayacu and Canelos) 

 through Mr. Buckley, I have been aide to compare it with this new form ; 

 and I have no douljt they are perfectly distinct from each other. In P. in- 

 (juinalis the 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.
