SOME NEW OH NOTEWORTHY SHELLS — HEDLEY. 145 



sutures. On each side ascend a series of nearly continuous 

 varices, which cause the shell to appear slightly compressed from 

 back to front. Aperture pyriform, outer lip advanced periph- 

 erally, columella margin thickened. Length, 2 25 ; breadth, 

 •0"65 mm. 



Compared with C. anceps, Hedley,^^ the novelty has less 

 developed varices and is much smaller and more slender. 



Hah. — A single specimen was taken by Mr. A. U. Henn, in 

 lOi fathoms near Bow Keef, off Cape Sidmouth, North 

 Queensland, 



SCAPHELLA MOSLEMICA, sp. nOV. 



(Plate xliii., figs. 29, 30). 



Shell small, thin, ovate-fusiform. Whorls three besides a 

 protoconch of three and a half whorls. In the adult the spire 

 whorls are coated with thick opaque callus. Colour cream to 

 salmon buff, longitudinally painted by about a dozen deeply 

 sinuate narrow cinnamon lines. Columella with four plications, 

 between the upper pair an interstitial thread sometimes occurs. 

 Length, 55 ; breadth, 25 mm. 



The novelty is closely related to S. undulata, Lamk., which it 

 i-epresents and teplaces in deep water, and from which it differs 

 by being a smaller thinner shell with a smaller protoconch and 

 having the spire whorls wrapped in a white sheet of callus. The 

 Tertiary fossil, Voluta inasoni, Tate,^^ approaches in form and 

 size but differs in colour pattern. 



Hab. — East of Sydney in 250 fg-thoms, off Wollongong in 100 

 fathoms, 80 fathoms 22 miles east of Narrabeen, (G. Hedley) ; 

 and deep water between Gabo and Flinders Island (Mr. H. C. 

 Dannevig). 



Marqinella geminata, sp. nov. 



(Plate xlii., fig. 28). 



Shell biconical, glossy, solid, and opaque in the old, thin and 

 translucent in the young. Colour uniform white. Whorls four, 

 flattened above the shoulder, contracted at the base. After
