usually exists behind the pillar. Height, 3.7; diameter at apex, 1.5; 

 maximum diameter, 2.5 mm. U. S. Nat. Mus. Cat. No. 107922. 



Off Fernandina, numerous specimens. 



The species differs from 107923 by its smaller size, relatively shorter 

 and less attenuated form, and slightly wider posterior part of the 

 aperture. It is dedicated to the late Dr. W. H. Rush, United 

 States Navy, to whom we were indebted for several interesting addi- 

 tions to the deeper water fauna. 



PYRUNCULUS MEDIUS. new species 



Shell small, white, polished, smooth, involved, the apex deeply 

 narrowly perforate; the whorl enlarging anteriorly; aperture as long 

 as the shell, very narrow behind, broad in front, the margin thin, 

 sharp, straight, in front evenly rounded into the slightly thickened 

 straight pillar; the latter has a narrow chink behind it; the poste- 

 rior commissure of the aperture is evenly rounded over. Height, 5; 

 diameter at apex, 1.5; maximum diameter, 3 mm. U. S. Nat. Mus. 

 Cat. No. 107923. 



Off Fernandina. 



There is no clearly defined plait on the three specimens col- 

 lected, but possibly it may develop later from the slight thickening 

 observable. 



PYRUNCULUS CURTULUS, new species 



Shell small, short, stout, whitish, smooth, the apex perforate in the 

 young, closed and funicular in the adult; aperture as long as the 

 shell, the outer lip raised slightly above the level of the spire, the 

 aperture very narrow behind, ample and evenly rounded in front; 

 pillar short, thin, slightly arcuate, showing no indication of a plait; 

 surface feebly marked by incremental lines. Length, 2.6; diameter, 

 1.5 mm. U. S. Nat. Mus. Cat. No. 108266. 



Off Georgia, six specimens. 



This is the smallest and most thickset relatively, of the east coast 

 species. 



Family BULLARIIDAE 



Genus BULLARIA Rafinesque 



BULLARIA INDOLENS, new species 



Shell small, white, smooth, except for faint incremental lines and 

 one or two accidental spiral striae, of about four whorls; apex a funic- 

 ular pit disclosing the edge of the whorls; form a slender oval; aper- 

 ture as long as the shell, narrow behind where the lip narrowly curves 

 to the body; outer lip mostly straight, rounded into the thickened 

 pillar which has a marked callosity at its anterior end; a narrow chink 

 lies behind the pillar but the base is imperforate; there is a coating
