Features

Holotype (description modified from McCulloch 1916): Dorsal fin 73; Anal fin 61; Lateral-line scales 77; Transverse scales 25/31.
Greatest body depth, measured on the lower surface, 3 in length to base of caudal-fin rays; head 5-7 in the same. Eye 6-8 in head length, equal in length to the interorbital space. Longest ray of right pectoral fin shorter than the eye, 7.3 in head, shorter than that of left pectoral, which is 5.4 in the head length. Eyes small, round, upper partly in advance of lower. Upper anterior nostril with a tentacle with a minute, inferior, secondary lobe at base, tentacle not reaching anterior margin of lower eye; posterior nostril opening into a short tube near lip in front of eye. Band of minute teeth on left side of both jaws. Mouth opening extending to anterior margin of lower eye; lips not fringed.
Fins damaged. Dorsal fin commencing in advance of upper eye, rays increasing in length posteriorly, posterior almost as long as caudal-fin rays. Anal fin similar to the dorsal. Caudal incomplete, rays equal to head length. Pelvic fins greatly damaged, opposite, subequal anteriorly,  separated from anal-fin rays by a short interspace. Pectoral fins minute, left fin slightly larger than right. 
Lateral line arching upward and forward on upper surface of the head, straight from behind head to middle caudal-fin rays. 
Scales ctenoid above and below except on lower surface of head, where they are cycloid; upper surfaces of fin-rays scaly, lower naked. Upper portion of head, except lips and anterior half of snout scaled; naked portion separated from rest by a fold of skin crossing snout, and connected with anterior dorsal-fin ray; lower surface of head naked anteriorly, with scattered cirri; interorbital space scaled.

Etymology

The specific name breviceps is from the Latin brevis (= short) and ceps (= head), in reference to the short head of this species.
