PROM TEE SOLOMON ISLANDS. 559 



Care must be takeu not to confound this species witli one or 

 two otJiers which are found from the same locality. C. tenelrosiis, 

 described by A. Adams in the Proc. Zool. Soc. 1851, p. 170, is a 

 narrower and more coarsely sulcated species than the present ; 

 and a second species (at present undescribed) is closely allied ; 

 it ^s umbilicated more broadly, spirally sulcated, and not so dark 

 in colour, being of a pale purplish tint with the spiral ]irs5 be- 

 tween the sulcations of a darker tint. Neither CantMridus 

 tenehrosiis, A. Adams, nor C. rufozona (also from JS^ew Zealand, 

 and of the same author) appear in Hutton's Catalogue of the 

 Marine Mollusca of that country, probably owing to their being 

 published without localities. I feel much pleasure in dedicating 

 this species to the author of the above very useful Catalogue.

This is a very pretty species, and of the following dimensions 

 — length, 12^ millims., diam. 9. The spiral granular liraj are 

 six on the penultimate, and about twelve on the last whorl. The 

 whorls are seven in number, somewhat convex, and divided by a 

 deeply but narrowly channelled suture. They have no longi- 

 tudinal lirse between the three upper series of transverse nodules 

 (which is not stated in Adams's very loose description), but are 

 only obliquely striated in this region. Only the lower half of 

 the whorls has a cancellated aspect. The longitudinal brown 

 markings are broadest at the suture, and not interrupted by the 

 transverse sulci on the upper part of the whorls ; but beneath 

 they appear on the grauose lirations in small spots.

As might be supposed from Mr. Adams's description, this 

 species is not uniformly " green." It is generally of a grey- or 

 sage-green ; and on the lower half of the body-whorl there are 

 some narrow radiating undulating pale stripes. The spccimeu 

 from the Solomon Islands is of a luteous colour above, and 

 tinged with greenisJi ash beneath, with tlie slender pale stripes, 

 and everywhere it is most minutely dotted with black upon the 

 spiral lirations.
