ANNOTATED LIST OF THE SPECIES 359 
Color in these specimens after sixty-five or more years in alcohol, upper parts 
pale, uniform brown, unmarked, verging into pale yellow below. 
Reported by Pentland to Valenciennes under the name Umanto, a Quichua 
word rendered also omanto. The species was not collected by us. Valenciennes 
was informed by Pentland that it appears on fishing grounds only at certain seasons. 
This may mean that for the rest of the year it migrates into deeper water, out of 
reach of our collecting gear and that of the natives. By Valenciennes it was re- 
ported as the largest, the most striking in appearance, and reputedly the best-

that of O. pentlandii. Garman reports that dead specimens with everted stomachs 
Fia. 43. Fish prepared for drying. Three of the commonest forms used for drying, the boca 
chica, palometa, and lisa, taken during the earlier stages of the rising waters of the rainy season in the 
mountains above. The Siamese-twin style of dressing small fishes is a standard procedure. 
were picked up on the shores of the island of Titicaca, possibly implying their 
having arisen after death from considerable depths. 
16077, 1, 73 mm., Moho bay, Lake Titicaca, Allen, December, 1918. 
This small, somewhat emaciated, and somewhat mutilated specimen is placed 
here by elimination and without much certainty, as a possible juvenile. It is, 
however, very unlike the specimens which Garman considered young cuviert. 
It is the most elongate of all my Orestias, not at all showing the robust proportions 
of the adult. Cuwzeri-like in the depth of the mouth, but without prominent teeth 
and lacking width. With the irregular rows of scales and extended caudal 
peduncle; eye large. 
Depth slight, 7.3 in the length; the elongated head 4.7; the interorbital width
