166 CANTHARUS. 



so that the body is mainly smooth. This and the next species 

 have been erroneously referred by H. and A. Adams and others 

 to the genus Clavella (= Cyrtulus),thQ type of which, G. serotina, 

 is a fusiform shell, with long canal, 



Doubtful Species. 



C. PORCATUS, H. and A. Ad, New Hebrides. 



An unfigured species, said to be a true Cantharus. 



C. STRIGOSUS, Jonas. Hab. Unknown. 



The name of Gmelin is quoted in parenthesis and with a query 

 as authority for this species : the Bucc. strigosum of that author 

 is, however, a Cassidaria. 



C. AMCENUM, Phil. Hab ? 



C. BUXEUS, Brod. 



Subfusiform, numerously undulately varicose, transversely 

 striated ; brown, transversely lineated with white ; aperture white, 



lip denticulated within. Length 30, lat. 17 mill,

 as a Murex. I give a copy of a figure in Sowerby's Conch. Illus-

 (Ocinebra} contractus, Reeve. 



C. ORUENTATA, Gmelin. 



In the Index to Vol. II, I have referred a portion of the 

 figures in Kiister representing Pur pur a cruentata to Pisaniinse. 

 Upon re-examining them I prefer to consider them as Kiister has 

 done. 



C. IMPROBUS, Gould. 



In the Index to Vol. II, I have referred this species to Pollia 

 (== Cantharus}. It is said to resemble buxeus, Brod., but is 

 shorter. Upon studying the description I believe the balance of 

 characters is decidedly in favor of considering it a Murex 

 ( Ocinebra), as originally described by Dr. Gould. It is unfigured,
