By those authors who would reconstitute the genus or sub- 
genus Gorsonia (Bellardi), founded upon a Tertiary fossil possess- 
ing one or more columellar plaits, this species and two or three 
others from Lifu would be included in it. At present we prefer 
following the arrangement as set forthin our National Collec- 
tion, and adding these new forms to the sub-genus GZyphostoma, 
and taking as the types G. crassilabrum Reeve and G. rugosum 
Mighels. The G. cremonilla cannot be confounded with G. 
nigrocinctum (Montrouzier) from New Caledonia ; it isa coarser- 
ribbed species, and banded with pale ochre, not black. Two 
specimens.

A very elegant little species, in good condition, somewhat 
ventricose, acuminate, semi-transparent, and straw-coloured, 
unicolorous excepting for the few square brown spots situate 
just above the sutures, between the longitudinal coste on the 
central whorls and continued in the middle of the last whorl, 
culminating in the specimen before us in a large dorsal square 
brown mark near the outer lip. The whorls, with the exception
