Hab. — Derwent River, Hobart, Tasmania. I iaave a specimen 

 of this species of a bluish-white with very few spots on the dorsum. 



Cypr^a Comptoni, J. E. Gray, Jukes' Voyage of H.M.S. Fly, 

 Vol. ii. Appendix No. x., p. 356 1847, PI. i. fig. 3. 



The following is his description: — "Shell ovate, grey-brown 

 (when young paler zoned), with three darker bands. Spire 

 small, flattened, hidden, right margin rather thickened, sharp 

 edged above, reddish white minutely black dotted, and stained 

 with black, brown above in front; left margin roundish, scarcely 

 thickened, brown dotted. Under side purplish brown, mouth 

 moderate, rather wider in front, teeth small, well defined, the outer 

 hinder ones rather the larger, the columella with an elongated 

 concavity in front not plaited. — ^Inhab. Port Essington."* 



I have not seen specimens from the north of Australia; some 

 from South Australia which I have seen are much darker in 

 colour than Tasmanian specimens, being a dark chocolate. 



Fig. 15, PI. x.x;i., is that of what I call a typical Tasmanian 

 specimen of C. Gomj)toni, measuring from the syphonal end to 

 the posterior apertural notch 24 mm., 15 mm. wide, and 11 mm. 

 high from base to the most prominent part of the dorsum, which 

 is a dull orange-brown colour: a slight dorsal sulcus covered with 

 small dark spots not showing on the base of shell, which is of a 

 pale orange-bi'own colour; on the left side of shell there are a few 

 indistinct spots showing on the base; the right columellar margin 

 with 23 teeth sloping into the aperture; the left has the teeth 

 tine, not visible on the base of shell. 



Fig. 16, PI. xxi., represents a variety of this species measuring 

 from the syphonal end to the posterior apertural notch 27 mm., 

 18 mm. wide, and 12 mm. high; dorsum a pale salmon colour all 

 over, with the exception of a slight trace of two bands of a lighter 

 colour; a slight dorsal sulcus with a few small brown spots, and 

 on the left a line of very faint spots, none of which show on the 



* Type in " My Cabinet." " The spots on the left side of the margin are 

 i-ather the largest, and tliere are no spots on the lower surface. Named in 

 honour of the Marquis of Northhampton, P.K.S."
