1. Bulimulus (Nassiotus) elaeodes, new species 



Shell small, ovate-conic, with six whorls separated by a 

 well marked suture, the nucleus strongly striated, the apex 

 dimpled, thin, fragile, with low feeble wrinkles, sometimes 

 strong on the base; color oily white, with irregular brownish 

 axial streaks, and a concentration of reddish brown in a nar- 

 row space in front of the suture and on the pillar; aperture 

 less than half as long as the shell, body without enamel, outer 

 lip very thin and sharp, pillar thin, short, straight with a 

 slight reflexion over a narrowly perforate umbilicus. Length 

 of shell 13.5 ; of last whorl 6.5 ; diameter 7.0 mm. 



Albemarle Island, on leaves, hibernating, at 1500 to 2300 

 feet elevation, near Banks Bay; Ochsner. 



2. Bulimulus (Nassiotus) hemaerodes, new species 



Shell small, livid pinkish brown, of five and a half whorls; 

 the apex dimpled, the nuclear whorls distinctly transversely 

 minutely ribbed; surface of spire polished, with microscopic 

 spiral striation not beaded; the transverse sculpture varying 

 in individuals from faint incremental lines to regular narrow 

 riblets or irregular ridges; on the last whorl especially the 

 most extremely rugose sculpture has a worm-eaten appear- 

 ance, while in other individuals the rugosities may be minute 

 and regular, or deferred to the last quarter of a whorl. Nor- 

 mal specimens show a pale, narrow peripheral band, but in 

 very rugose individuals this is lost ; the last whorl, especially 

 when very rough, is whiter than the rest of the shell; mar- 

 gin of the aperture thin, sharp, the outer lip not reflected, the 

 umbilicus a narrow perforation; the axis continuously tubu- 

 lar, simple, not twisted. Length of shell 12 • ; of last whorl 

 9 ; diameter 7 mm. 



Hibernating under dead wood on Cowley Mountain, Albe- 

 marle Island, between 2100 and 2300 feet elevation, in the 

 grassy zone ; and hibernating on the grassy rim of the crater 

 of Narborough up to 4500 feet ; Ochsner. 



3. Bulimulus (Naesiotus) perrus, new species 



Shell small, shiny, ruddy brown, a narrow pale area in 

 front of the suture; apex blunt, dimpled nucleus faintly
