OCINEBRA. 125 



Through the kindness of Mr. R. E. C. Stearns I am enabled to 

 give a figure from one of the types (fig. 440). 



M. FOVEOLATUS, Hinds. PI. 38, fig. 465. 



Varices seven, simple. Dark brown, with two lighter bands. 



Length. 1 inch. 



Magdalena Bay, L. Gal. 



This species has been referred to Vitularia by Kobelt, but the 

 figure is a characteristic Ocwebra. The species has not been 

 certainly recognized by any recent collectors. 



M. SUBANGULATUS, Stearns. PL 38, fig. 466. 



Varices seven to nine, crossed by irregular revolving line. 

 There is a brown band composed of three brown lines; otherwise 

 white. Lip with five or six tubercles within. 



Length, '89 inch. 



San Miguel Isl. off southern coast of CaL, (two specimens). 



Resembles somewhat M. foveolatus above, and also recalls 

 Vitularia xcilebrotia, King ; especially the white variety of Reeve's 

 monograph, which I have figured. 



M. EXTGUUS, Brod. PI. 31, tig. 451. 



Varices live, frondose, fronds short; transversely ribbed, ribs 

 prominent ; spire short ; canal medium, recurved; dirty white. 



Length, -37, breadth, *25 inch. 



Siilango, W. Columbia, sandy bottom at 10 fathoms. 



Evidently a very young shell. 1 give a figure from Sowerby, 

 said to represent the species. 



M. LAPPA, Brod. PI. 37, tig. 434. 



Light brown, the short spines of the varices darker in color. 



Length, 1*25 inches. 



St. Elena, W. Columbia ; rocky bed at depth of 12 fathoms. 



Here an'ain I figure Sowerby ? s representation of the species ; 

 the figure in Reeve appears to nie to be more like ,17. rittahtx, 

 Brod. Will not this shell prove to be the adult of M. exiguus? 



M. RADICATUS, Hinds. PI. 37, fig. 443. 



Five varicose, compressly lacinated on the varices. Light 

 brown or whitish. Length, '8 inch. 



San Bias, W. C. of Mexico, in mud at 11 fathoms. Mazatlan.
