 depth 7.5; D. 7; A. 6; interorbital 5 in the head, equal to 

 distance of anterior nares from snout, less than distance between 

 and posterior nares; distance between snout and dorsal 2.75-3 

 in the length; distance of anal from caudal 5-5.5 in the length; dorsal 

 rounded, the first ray not produced; outer pectoral ray not produced, 

 not reaching middle of ventrals; origin of ventrals nearly under origin 

 of dorsal; tips of ventrals nut reaching over two-thirds to anus; adi- 

 pose fin scarcely evident. Outer teeth of the premaxillary narrow, 

 single pointed; teeth of the lower jaw, like those of the inner series 

 of the premaxillary, bifid. Barbel not quite reaching gill-opening. 

 Brownish, slightly marbled.

 Small stream in highlands, southeast of Tarma. Named for Miss Lola

Paralleling in general appearance Cyclopium sabalo, with which it 

 was associated. Head 4.75; depth 7.6; I). 7; A. 9; eye 2 in snout; 

 5.5 in head; 1.75 in interorbital. Adipose dorsal 4.5 in the length;

 in it- length. Jaws equal; premaxillary hand of teeth of equal width 

 throughout, without a backward projecting angle at the side; pectorals
