The nearest relative of this species appears to be the Bulla / 

 CII/K* of Europe, which is longer, less cylindrical, and has a deep pit 

 at the apex. I have been enabled from an inspection of his type 

 to determine that the manuscript name of Dr. Jeffreys applies to this 

 species. (I tail). 



B. GEMMA Verrill. Unfigured. 



Shell white, rather solid, resembling, in size and form, Qyliclmn 

 occulta (Migh.), but distinguished by having a small, distinct um- 

 bilicus, and also a narrow deep pit at the apex of the spire. Sculpt- 

 ure, a few distinct spiral lines at each end ; middle region of shell 

 smooth. Length, 4'2 ; breadth, 2'5 mill. ( IV). 



Outer banks, off Southern New England (U. S. Fish Com. sta- 

 tions 871, 873).

B. EBURNEA Dall. PL 36, fig. 21. 



Shell small, ivory-white, polished, ovate, the aperture extended 

 posteriorly a little beyond the left hand summit of the whorl ; sculpt- 

 ure, a few spiral grooves near either extremity, rnim i numerous and 

 crowded anteriorly ; these grooves somewhat zigzag from irregular- 

 ities of growth, but not puncticulate; remainder of the shell with- 

 out sculpture, except most minute microscopic faint indications of 

 spiral stria- and faint lines of growl h ; apex minutely pitted, but the 

 pit nearly covered by a small reflection of the lip where it j'>ins the 

 posterior foce of the body; outer lip thin, -harp, curved round and 

 reflected at the anterior end of the axis; a thin deposit over the
