Rnnarks. The type and only specimen secured was taken in a small 

 cistern at the western end of the town of Huancabamba. The junior 

 author was searching for Gastrotheca larvae in this cistern, not three 

 feet in diameter, when he suddenly espied this good-sized frog. None 

 of the boys present seemed to know it, for to his urgent " Conio se llama

 manner by which the Peruvian " cholo" signifies that he does not know. 

 Diligent collecting in the streams about Huancabamba for a month 

 did not reveal another specimen.

 the jaws.

Type. M. C. Z., 1,077 from bottom of Lake Titicaca, Peru; taken 

 dredging by S. W. Garman, in eleven fathoms off Achacache, Bolivia. 



Description of Type. Size very large; length of the head contained in the 

 breadth 1.5 times, in the total length 3.8 times; snout round, very flat without 

 canthus roslralis; nostril minute, slightly nearer the orbit than the labial
