orbital level, with well developed median ridge and two 
smaller supercilliary ridges on each side. Cheeks and pre- 
opercle with wide ste radiating lines; opercles smooth or 
with only very obscure traces of striae. 
Gill openings forward to about last third in snout. 
Gill-rakers 70 - 130, very slender, fine, little longer 
than filaments or about as long as snout. Pseudobranchiae 
large, though little smaller than gill-filaments. Isthmus 
slender, long, notch inside gill-opening below and 2 fleshy 
points above. 
Scales rather caducous, many having fallen, large, 
rather narrowly imbricated, smaller on back and caudal base; 
vertical striae 4 or 5, usually divided medially or at least 
most all except outermost. Dorsal origin about midway between 
mandible tip and last anal ray base. Anal midway between 
ventral origin and caudal base. Pectoral low (damaged), near- 
ly half way to ventral, and latter inserted opposite Tirat 
fourth in dorsal length, small. In alcohol brown on back, 
sides and below pale brassy-brown. Fins dull. 
One 135 mm. long (caudal damaged), from"Callao”, prob- 
ably erreneous as the specimen was likely procured at Rio 
Janeiro?. Also one from the last locality 67 mm. (caudal broken) 
and another without data 123 mm. (caudal broken). The last 
shows: Head 3 1/3; depth 3 7/8; D. iii, 15; A. 
scales 45 in lateral series to caudal base and 5 more on 
latter; 11 scales transversely at dorsal origin: 17 prédorsal 
scales; snout 3 1/3 in head; eye 4 1.6; maxillary 2 2/5;
