Hurron.—On Rhachiglossate Mollusca. 233 
This species has been very well figured by Quoy. It is distinguished 
from C. costata not only by its form and colour, but also by the tentacles 
being slender, with the eyes near the middle; whereas in C. costata, 
according to Quoy, the tentacles are * short, thick, and rounded at the tip, 
close to which the eyes are placed.”

Hab. Throughout New Zealand on mud flats, and in slightly brackish 
water. 
Yellowish-gray to brown-purple, the lighter varieties occasionally show- 
ing faint spiral lines of darker, the aperture is about half the length of the 
shell, and is dark purple, usually mottled with yellow. There are about 
twelve plications on a whorl. The operculum is normal. The dentition is 
figured in Trans. N.Z. Institute, xiv., pl. vi., f. 0. 
This species is quite distinct from C. acutinodosa, Reeve, from $. Aus- 
tralia. 
Sub-fam. Nassine. 
Animal with the foot large, and carrying at its posterior extremity two 
small processes. Central tooth pectinated ; laterals with two cusps, and 
sometimes intermediate serrations. Shell with the inner lip usually callous ; 
the canal short and recurved, or a notch. Operculum ovate, the nucleus 
apical. 
- Genus Nassa, Lamarck. 
Shell ventricose; inner lip with a posterior callosity, or blunt, dentiform, 
plait ; outer lip dentated, internally crenulated.

Hab. N.E. of New Zealand in 700 fathoms. 
Rather small, thin, chalkily porcellanous ; ovate, with a shortish scalar . 
spire, a rounded apex, a marginated suture, and a tumid base with very 
short pillar. Whorls rounded and beset with small prickles. 
I have not seen this species, which was obtained by the Challenger 
expedition. ;
