BULLETIN OF THE UNITED STATES FISH COMMISSION. 
second dorsal two-fifths length of head; origin of anal fin vertically below tenth ray of second dorsal 
base of outer ventral ray midway between origin of anal and front of eye; vent more anteriorly 
placed than in related species, its distance from front of anal equaling two-thirds orbital diameter. 
Scales unarmed, with very fine concentric striae. The lateral line runs posteriori}' a little below middle 
of sides, and rises anteriorly by a gently concave curve, differing strikingly in this from most other 
species of the genus, in which the lateral line describes a strong convex curve above the pectorals. 
Scales covering top and sides of head, and present in a series along mandibular ramus; absent on opercu- 
lar and gular membranes. About 9 to 11 scales in a series between the straight portion of lateral line 
and base of dorsal. 
Gadomus colletti Jordan & Gilbert, new species. Type. 
Color in spirits, light brownish on back and sides, silvery on cheeks and under side of head, 
and corresponding portions of trunk; breast and under side of head coarsely specked with brown. 
Upper portion of opercular membrane blackish. Snout dusky. First dorsal fin blackish throughout, 
including filamentous ray. Second dorsal with a black margin, fin otherwise light in anterior portion, 
bright blue posteriorly. Anal whitish, black near end of tail. Pectorals and ventrals blackish or 
dusky, the filaments and tips of rays whitish; lower lip dusky, but anterior mouth parts, including 
membranes, otherwise whitish; roof and posterior parts of mouth blackish; gill cavity black, save a 
wide margin on inner side of opercular and gill membranes, which becomes abruptly whitish and 
contrast's strongly; peritoneum jet black. 
One specimen obtained by the Albatross in Suruga Bay.

EEGANIA Jordan. 
Reyania Jordan, new genus (nipponica) . 
This genus differs from Gadomus in the absence of the mental barbel. The hypercoracoid is per- 
forate as in Gadomus. There is also, as in Gadomus and Melanobranchus, a slit behind the last gill.
