76 CANCELLARIA. 



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



Turreted, whorls narrowly, flatly shouldered, longitudinally 

 narrowly ribbed, faintty 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. LengtTi, 16 mill.

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



Shell turreted, with shouldered whorls, the angle of the 

 shoulder slightly 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. MACROSPIRA, Ads. and Reeve. PI. 4, fig. 67. 



Occasional^ varicose, decussately finely ridged, suture exca-

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.

 Phil., is a synonym.
