Two species of the genus were taken, but, unfortunately, the 
individual records were lost. The three southern Stations were 
made northwards of Dunedin to the Canterbury Bight, and the 
three northern ones in Hawke Bay and the Bay of Plenty, 
the recorded depths being 9 to 105 fathoms.

Length of head 3.5, height of body 2.6, length of caudal 5.3 
in the length; diameter of eye 4.1, interorbital space 2.4 and 
length of snout 3.2 in the head. 
The upper and lower profiles of head and body form low even 
curves, the dorsal being the more convex: the eye lies wholly 
in the anterior half of the head and the nostrils are situated 
quite close to the end of the snout; the mouth is small, the 
maxilla not reaching the eye, it has a supplemental bone, the 
upper edge of which slips entirely under the preorbital; gill- 
rakers long, twenty-five on the first arch, of which seventeen are 
on the lower limb; opereles entire.
