8.5, of peritreme 4.5, max. diam. 6.5 mm. 
Type locality: —Newport, Cal. (H. N. Lowe). hy 
Monterey, Cal., to Coronado Islands, Baja Cal., in 16-34 fms. 
1470 Epitonium (Crisposcala) Catalinz Dall. 
Shell slender, white, turrited, imperforate, with more than 7 
adherent whorls; nucleus (lost); suture distinct, closed; varices 
(on the last whorl 14) continuous, making nearly one revolution 
around the axis in ascending the spire; they are flatly reflected, 
axially striate, subspinose at the shoulder, giving a tabulate as- 
pect to the rounded whorls. There is no basal disk on the whorl 
but on the basal part of each reflection of the varices there is a 
smooth area over which the suture travels, and which, taken col- 
lectively, gives the effect of segments of a disk imposed on the 
varices but not on the whorl; below the shoulder the varices are 
widely reflected, extending for a space to the angle of reflection 
of the preceding varix, where it would seem these extensions are 
normally attached, covering a hollow space between them and 
the whorl, but in the type-specimen most of these extensions are 
broken away; aperture subcircular. Height of (decollate) 6 
whorls 12, of last whorl 6, of aperture 2.7, max. diam 4.5 mm. 
Type locality:—off the south side of Catalina Island, Cal., in 
16 fms. (W. H. Dall). 
1471 ?Eulima Lomana Dall. 
Shell slender, acute, flat-sided or nearly so, chalky white, with 
an extremely thin yellowish external coating; nucleus eroded; 
subsequent whorls very slightly convex, with an obscure periph- 
eral angle on last whorl, upon which the suture of the advancing 
whorl is closely appressed; surface smooth and polished except 
for very obscure and minute spiral lines only visible in good light 
with a lens; base convexly rounded, imperforate; aperture ovate- 
quadrate, outer lip simple, thin, gently arcuate; body bare, pillar 
almost straight, twisted and with a very obscure prominence like 
an obsolete plait; an examination of the interior of the upper 
whorls, however, show no plication; anterior of aperture gently 
rounded; there are no indications of varices or resting stages on 
spire. Height of shell 20, of last whorl 10, of aperture 6.5, max. 
diam. 7 mm. . 
Type locality:—16 miles off Point Loma, San Diego, Cal.,. in 
about 650 fms. 
1472 Odostomia (Evalea) atossa Dall. 
Shell small, bulimiform, bluish white, polished, with 4 gently 
convex whorls beside a very minute (and somewhat eroded) nu- 
cleus of about one whorl; suture distinct, not appressed; surface 
with 2 or 3 faint spiral threads on the second, 4 or more on the 
3d, becoming obsolete on the last whorl, subequally distributed 
between the sutures; besides these there are numerous extremely 
fine spiral strize only visible under a lens, and which also become 
obsolete toward the aperture; aperture subovate, acute behind; 
outer lips simple, sharp;anterior margin gently rounding into 
the arcuate pillar lip, which has a single strong plait close to the 
body; a thin wash of transparent enamel on the body; axis ‘im- 
perforate; operculum thin, paucispiral, pale yellowish. Height of 
shell 6.25, of last whorl 5, of aperture 3.25, max. diam. 3.7 mm. 
1473 Trichotropis? Kelseyi Dall. “i 
Shell small, whitish, with a velvety pale olive periostracum 
and 3% whorls; spire very short; suture very deep, not chan-
