OCINEBRA. 125 



Tluoiigli 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. .S8, fig. 465. 



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



Length, 1 inch. 



Magdalena Bay, L. Cal. 



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

 figure is a characteristic Ocinebra. The species has not been 

 certainly recognized by any recent collectors. 



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



Varices seven to nine, crossed by irregular revolving lirae. 

 There is a brown band composed of three brow'n lines ; otherwise 

 white. Lip with five or six tubercles within. 



Length, -89 inch. 



San Miguel Isl. off" soutliern coast of Cal., (two specimens). 



Resembles somewhat M. foveolatus above, and also recalls 

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

 monograph, which I have figured. 



M. EXIGUUS, Brod. PI. 37, fig. 45L 



Varices five, frondose, fronds short; transA'ersel}^ ribbed, ribs 

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



Length, -37, breadth, -25 inch. 



Salango, W. Co^tt/wi/a, sandy bottom at 10 fathoms. 



Evidently a very j'oung shell. I give a figure from Sowerby, 

 said to represent the species. 



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



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



Length, 1-25 inches. 



8t. Elena, W. Columbia ; rocky bed at depth of 12 fathoms. 



Here again I figure Sowerby 's representation of the species ; 

 the figure in Reeve appears to me to be more like M. vittatus, 

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



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.
