1940, by Dr. Mann. 
Paratypes—U.S.N.M. No. 118741, 33 specimens, 28 to 52 mm. 
standard length, bearing same collection data as the type; U.S.N.M. 
No. 118742, 42 specimens, 32 to 48 mm., taken by Dr. Mann at Brom- 
ley; U.S.N.M. No. 118743, 1 specimen, 29 mm., collected by Dr. Mann 
at Harbel. 
Description.—This description is based on the holotype and the 
76 paratypes listed above. All measurements are expressed in 
hundredths of the standard length, those for the holotype first, 
followed by measurements of one of the paratypes. Total length

28.5; length of snout 7.7; 9.9; greatest depth of body 25.1; 23.3; 
diameter of eye 10.1; 9.9; width of fleshy interorbital space 8.2; 9.05 
postorbital length of head 12.3; 12:1; least preorbital or distance 
from eye to lower edge of preorbital near rear of maxillary 2.2; 2.5; 
distance from tip of snout to rear of maxillary 8.4; 8.5; length of 
anterior barbel 12.8; 11.2; length of posterior barbel 13.0; 11.8; 
length of caudal peduncle or distance from rear base of last anal 
ray to midbase of caudal fin 20.7; 19.2; least depth of caudal pe- 
duncle 13.2; 13.2; distance from snout to origin of dorsal 50.8; 50.7; 
snout to origin of anal 73.5; 74.6; snout to insertion of pelvics 52.2;

20.7; 18.1; longest ray of pectoral 21.2; 19.7; longest ray of anal 
17.8; 18.1; longest ray of caudal 32.5; 31.5. 
The following counts were made: Gill rakers on one paratype 
were 2+4 or 5; scale rows crossing lateral line 27; 28; 27; 28; 27; 
scales above lateral line always 414 and below lateral line (pelvic 
base to lateral line) always 214; scales around caudal peduncle 
always 12; scales in front of dorsal fin 10; 11; 10; 10; 10; dorsal 
rays always ili, 8; anal always ili, 5; pectoral 14-14; 15; pelvic 
always 8; pharyngeal teeth on one paratype 5:3: 2-2: 3:4. 
Scales rather large, radiately striate; lateral line complete; two 
pair of barbels both of about same length and a little longer than eye; 
no parallel lines of minute pores on the head; mouth slightly inclined, 
subinferior, the snout projecting a little; groove of lower lip inter- 
rupted by a frenum at tip of chin; premaxillary protractile; interor- 
bital space flattish ; body somewhat compressed ; pelvic insertion under
