 201*. Pour young valves (smallest '05 by •034) probably of tliis species. 

 266*. Minute transparent valve, '028 across, teeth unformed; perhaps of 



this species. 

 358*. Two specimens ; margin irregular. 

 594*. Several specimens in Uvanilla unguis ; one, not having room within, has 



made a case for itself outside the Uvanilla. 



642*. A pair, -3 by -15 ; probably an older state of the same species, Barbatia

 dorsal margins. 

 833*. Two young specimens, nestling among NuUipore on Fissurella alba,

 876*. One specimen, curiously mended after fracture. 

 877*. One specimen, with columella curiously contorted, 

 1023*. One specimen, with ribs rounded and aspect of Siphonaria lecanlum ; 



probably a distinct species. 

 1058*. One young specimen, probably conspecific, though only -07 by -047 ;

posterior tooth, and the anterior hooked tooth is separating into two. 

 [2534. One specimen of Vifrinella '? tricarinafa, jnn., of which the ribs are 

 nodulous in the young state. If rightly determined, this adds no. 710 

 to the list of species.] 

 2536. A nuclear shell, '046 across, of Naticoid shape, very finely striated in each
