- 
With uncertainty I am referring to this species a specimen from 
Rio San Pedro at bridge, south of Mene Grande, collected March 
20, 1942 (U.S.N.M. No. 121563), 59 mm. in standard length, not 
as a paratype, because it has the secend suborbital not in contact 
with preopercle. The fin rays are anal 11,24; dorsal u,8; pelvic 
1,7-1,7; pectoral 1,12-1,12; scales 41, 7 above and 5 below lateral 
line; teeth 5-5 in outer row, 4-4 in mner row on premaxillaries; 
maxillary with about 5 teeth.

length, respectively, for the holotype and the paratype in paren- | 
theses. Standard length in mm. 96 (86). 
Length of head 26.0 (26.7); greatest depth 32.8 (34.9); length of
