Type. Distorted small fish; Geneva Museum. 
A small species known by nearly complete fishes attaining a 
length of about OB. Length of head whth opercular apparatus 
much exceeding the maximum depth of the trunk and occupying 
one third of the total length to the base of the caudal fin. The 
mandible, operculum, and most of the other external bones orna¬ 
mented with fine tuberculated ridges. Palatine bone produced 
forwards as a short cylindrical extension in advance of the ethmoid 
articulation, and the long slender tooth fixed at its extremity ; 
outer face of premaxilla apparently smooth; dentary rapidly con¬ 
tracting almost to a point at the symphysis, and the maximum 
depth of the mandibular ramus contained about three and a half or 
four times in its total length. Teeth slender, much compressed, 
and often delicately striated. Vertebrge about 40 in number, 24 
being caudal. Pelvic fins somewhat smaller than the pectorals, 
arising opposite the anterior half of the dorsal; dorsal fin with 16 
rays, its depth about equalling that of the trunk at its insertion ; anal 
fin much smaller, with 18 rays, arising nearer to the pelvic fins than 
to the caudal. Dorsal scutes three or four in number, broadly oval, 
and ornamented with delicate radiating lines.
