oblique (blunt angle of which would form below middle of eye); eye rather large, high, in posterior 
third of length of head; nostrils small, close together, anterior with small thin flap, circular, posterior 
a small slit; interorbital space broad', convex; dorsal spines strong, graduated to posterior, last 1.3 in 
head; first anal ray 1.25; anal spines graduated to third, longest 1.65; fourth anal ray 1.25; caudal 
broad, emarginate; pectoral pointed, 2.8 in body; ventral sharp-pointed, 4 in body; ventral spine, 2 in 
head; caudal peduncle compressed, its depth 2; caudal spine moderately long, depressible in a groove, 
4 in body. 
Color in life of the type (No. 50712, (J.S.N.M. ), a whitish band from base of first 2 dorsal spines 
downward behind eye, including opercle to its lower margin; also a transverse whitish band at base 
of caudal. 
Color in alcohol deep brown, vertical fins and ventrals darker; top of head and space in front of 
spinous dorsal pale brown, running down as an oblique band along gill-opening over opercle and margin 
of preopercle; base of last dorsal rays blackish; base of caudal pale brown. 
Described from the type taken at Honolulu by Doctor Jenkins. The species is thus far known only 
from Honolulu, whence we have 9 specimens, and from Hilo, from which we have 1. These specimens 
vary in length from 3.7 to 8.75 inches. Seen alive in aquarium at Waikiki.

in a groove; scales small, finely ctenoid, very small on top of head, breast, and basal portions of 
vertical fins; lateral line irregular, arched at first, then sloping down to caudal spine, more or less

pectoral pale olivaceous brown; ventrals blackish on outer portion. 
The above description is from the type (field No. 05363), a specimen 7.5 inches long, taken at 
Honolulu by us, where we obtained 1 other example. A single small specimen was obtained by 
Doctor Jenkins, and the Albatross secured others at Puako Bay, Hawaii.
