148 ATILTA. 



In the general form and aperture this species looks something 

 like a Strombina. 



C. SUBULATA, Duclos. PI. 52, fig. 96. 



Shell with a long, sharp-pointed spire of eleven flattened 

 whorls, the body-whorl striate and produced below into a long 

 narrow canal ; aperture long and narrow ; outer lip thickened 

 and dentate within ; yellowish white. Length, 28 mill. 



Habitat unknown. 



The above description is made up from the original figures, 

 one of which I copy. The shell may be a fossil. Sowerby subse- 

 quently described a very different species under the same specific 

 name. 



C. PLURISULCATA, Reeve. PI. 52, fig. 95. 



Yellowish brown, spirally grooved throughout, aperture sinu- 

 ated posteriorly, lip unarmed. Length, 12 mill. 



Habitat unknown. 



Described from a single, worn and perhaps not adult specimen : 

 it must be considered a doubtful species. 



C. ARATA, Reeve. PI. 53, fig. 97. 



Shell spirally grooved throughout ; yellowish, variegated with 

 red-brown spots ; columella excavated ; lip simple, slightly 



expanded. Length, 14 mill. 



Habitat unknown. 



C. OCELLATA, Reeve. PI. 53, fig. 98. 



Shell finely longitudinally plicate, with revolving grooves at 

 the base ; whitish, stained and ocellated with orange-brown. 



Length, 8 mill. 



Habitat unknown. 



The eye-like points are said to dip at rather distant intervals 

 from the sutures. A doubtful species. 



C. PELAGIA, Reeve. PI. 53, fig. 99. 



Shell subulate, the whorls somewhat tubercularly ribbed above, 

 forming a turreted spire ; aperture small, lips strongly varicose, 

 notched at the upper part, plicate within : white, marbled with 

 chestnut, showing a more or less defined white central band, and 

 white on the sutural tubercles. Length, 8 mill. 



Habitat unknown.
