BULLETIN OF THE UNITED STATES FTSH COMMISSION. 
Pectoral fin with 16 rays; dorsal low but distinct, its origin well behind tip of pectoral. 
Color whitish translucent with slight luster; end of tail rendered slightly dusky by scattered 
pigment spots; occiput dusky, snout and tip of mandible slightly so. 
From F. homei (Richardson), this species differs in its small and more oblique mouth, smaller 
teeth, and less slender tail; from F. brandesii (Bleeker), in smaller teeth and longer pectoral. 
Only the type is known. 
Jordanicus new genus ( Fierasferidse'). 
Jordanicus Gilbert, new genus of Fierasferidse (Fierasfer umbratilis Jordan & Evermann). 
Differing from Fierasfer in the depressed head, which is as broad as it is high, and especially in the 
adnate maxillaries and the lack of a distinct lower lip; the skin of snout and suborbital region passes 
without fold or other interruption over the maxillary and premaxillary, both of which are thus con- 
cealed and firmly bound down; mandible broad and fiat; fleshy margin of jaw wide, flattened to an 
edge, extending well beyond dentary portion of jaw, but not separated by a fold from the integu- 
ment covering the mandible; the mandibular teeth are opposed to the palatine band, and the 
expanded fleshy margin of mandible shuts within the premaxillary series both anteriorly and laterally; 
no pronounced fold of integument along inner margin of the mandible; branchiostegals 7. 
Jordanicus umbratilis (Jordan & Evermann). 
A single specimen, 146 mm. long, was taken in Puako Bay, Hawaii. It is exclusively a shore 
species, introduced here for purposes of comparison with Fierasfer. 
The angle formed by the gill-membranes on median line below is behind eye a distance equaling 
half diameter of latter; premaxillary teeth minute, confined to anterior half of jaw, apparently in a 
single series; mandibular and palatine teeth also in single series, those on sides of mandible directed 
laterally toward angle of mouth, none of them enlarged; 2 or 3 vomerine teeth are the largest in the 
mouth, and are arranged in a longitudinal series. 
Fierasfer parvipinnis Kaup, resembles this species in the depressed head and tumid cheeks, but 
according to Kaup’s figure, it is a true Fierasfer.

Family GADM. 
Antimora microlepis Bean. 
One specimen, 465 mm. in total length, was taken at station 4185, in the vicinity of Kauai, at a 
depth of 1,000 to 1,314 fathoms. 
The number of fin-rays is slightly below the normal for microlepis. Abundant material might 
show that the Hawaiian representative is specifically separable, but direct comparison with typical 
microlepis from Alaskan waters has developed, no further differences.
