166 CANTHARUS. 



SO that the bod}- is mainly smooth. This and the next species 

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

 to the genns GlaveUa (= Cyi'tulus), the type of which, G. serotina^ 

 is a fusiform shell, with long canal. 



Doubtful Species. 



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



An unflgured species, said to be a true Ganfharus. 



C. STRIG08U8, Jonas. Eab. Unknown. 



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

 as authorit}' for this species : the Bucc. strigosum of that author 

 is, however, a Gassidaria. 



C. AM(ENUM, Phil. ffab ? 



C. BUXEUs, Brod. 



Subfusiform, numerousl3' undulately varicose, transversely 



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



lip denticulated within. Length 30, lat. 11 mill, 



Peru. 



Is a Gantharus., according to Dr. J. E. Gray, but was described 

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

 trations (PI. 74, fig. 303) which, if it truly represents the shell, 

 shows it to be a 3Iurex, closely allied to, if not identical with M- 

 (Ocinebra) contractus^ Reeve. 



C. CRUENTATA, Gmelin. 



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

 figures in KUster representing Purpura cruentata to Pisaniinae. 

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

 done. 



C. iMPROBUs, Gould. 



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

 (= Gantharus). 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 b}' Dr. Gould. It is unfigured,
