DESCRIPTION OF A NEW SPECIES OF OCINEBRA. 

 BY JOHN FORD. 

 Ocinebra Michaeli, Ford. 



Shell fusiform, rather slender, turreted, light gray, with a narrow 

 median brown band ; whorls 5, convex, shouldered above, the upper 

 ones carinate ; sculptured with numerous rather coarse revolving 

 lirations, the interstices with riblets bearing crowded festooned 

 lamellae of growth, which are also prominent below the sutures; 

 longitudinally prominently plicate, with about seven folds to each 

 whorl; aperture oval, white within, angular above; anterior canal 

 quite long, open, straight; outer lip thickened within, bearing six 

 small tubercles; columella nearly straight ; with a whitish callus 



projecting slightly at beginning of canal. Length of shell 16, diam. 

 8 mill. Length of n perture 9 mill. Hab., Cayucos, San Luis Obispo 

 Co., California. Differs from 0. intei-fossa Cpr., in having open canal. 

 0. subangulata Stearns, is somewhat related, but is much longer, 

 ess angulated, aperture more rounded and .without the internal 

 tubercles shown by 0. Michaeli. So far as can be learned, this small, 

 but distinct species, has been found only by Mr. Geo. W. Michael, 

 Jr., after whom it is deservedly named ; the gentleman being not only 

 an efficient collector, but a careful student of science also. Al^out 

 forty specimens have been secured alive by him at the locality 

 mentioned, which is the only one known at present.
