76 CANCELLARIA. 



C. T^NIATA, Sowb. PI. 4, fig. 64. 



Turreted, whorls narrowly, flatly shouldered, longitudinally 

 narrowly ribbed, faintly spirally ridged ; colurnella two-plaited ; 

 reddish brown, with darker spiral lines. Length, 15-20 mill. 



Hob. unknown. 



Scarcely a member of the group. 



C. ELATA, Hinds. PI. 4, fig. 65. 



Strongly ribbed, spirally ridged; columella three-plaited; 

 brownish yellow. Length, 16 mill. 



Panama (30 fms.), Hinds. 

 C. COOPERI, Gabb. PL 4, fig. 66. 



Shell turreted, with shouldered whorls, the angle of the 

 shoulder slightty coronated by the terminations of narrow, 

 distant longitudinal ribs, the interstices closely spirally striate ; 

 columellar plications small ; yellowish brown, darker on the 

 shoulder, with rather regular narrow spiral chestnut lines. 



Length, 2*5 to nearly 4 inches. 



Monterey and San Diego, Gal.

 C. taeniata, Sowb.; that is, supposing the latter to be a young 

 specimen. I owe to R. E. C. Stearns, Esq., the opportunity of

 specimen in the Hermann Collection, San Francisco. 



C. MACROSPIRA, Ads. and Reeve. PI. 4, fig. 67. 



Occasionally varicose, decussately finely ridged, suture exca- 

 vated ; whitish, semipellucid. Length,. 1 inch. 



Borneo ; China Sea. 

 C. CORONATA, Scacchi. PL 4, fig. 68. 



Turreted, excavated below the suture, longitudinally distantly 

 costate, ribs projecting at the shoulder angle, spirally striate. 



Length, '75 inch. 



Mediterranean Sea. 



Described as a fossil species, but recently recorded by Dr. J. 

 Gwyn Jeffreys as living in the Mediterranean. C. varicosa, 

 Phil., is a synonym. 



C. ANGASI, Crosse. PL 4, fig. 69. 



Imperforate, thin, subscalariform, flat-shouldered, with a carina 

 at the angle, another carina below the middle of the body-whorl,
