Stations 25, 28, 30, 65. 
D. 32; P. 18; Rings 11 + 49 — 60. 
Snout long, equal to the post-orbital portion of the head, the 
supraorbital ridges rise together abruptly at the base of the 
snout, and diverging form a simple spine over each eye, pointed 
outwards and backwards and terminating in a short filament; 
coronet low compressed, with a median filament in front and 
two behind placed on low knobs. 
Body very deep, the depth at 
the tenth ring being two and a third times the length of the 
snout; the spines are represented by low knobs slightly enlarged 
below the dorsal, a filament on the dorsal knob of the third body 
ring.
