Subgenus Leucophysema Dall 



LEUCOPHYSEMA EBURNEOLA Dall, new name 



Bulla 1 ehurnea Dall, Bull. Mus. Comp. Zool., vol. 9, p. 98, 1881; vol. 18,

Shell small, ivory white, smooth, polished, with a few faint spiral 

 striae on the base; whorls involved, the apex minutely perforate, 

 the aperture as long as the shell, the margin roundly curved behind, 

 gently arcuate laterally, thin, roundly curved to the short thickened 

 pillar; the adult appears to have the umbilicus closed, younger speci-

 apical funicle. Height, 6; diameter, 3.5 mm. U. S. Nat. Mus. Cat. 

 No. 107925.

LEUCOPHYSEMA ABYSSICOLA Dall 



Shell small, ovate, white, smooth, except for fine spiral striae near 

 the apex; the whorls involved; apex with a shallow dimple; aper- 

 ture as long as the shell; the posterior commissure narrow; outer lip 

 thin, sharp, moderately arcuate, rounding evenly into the slightly 

 thickened short pillar; base imperforate; body with a thin coat of 

 enamel. Height, 4.5; maximum diameter, 3 mm. U. S. Nat. Mus.

These differ from 107925 in being smaller, proportionately shorter, 

 and more rotund. They are probably the young of the much larger 

 L. ahyssicola, though I have received them under the name of Di- 

 apJiana gemma Verrill, which is of a quite different shape.
