8.5, of peritreme 4.5, max. diam. 6.6 mm. 



Type locality: — Newport, Cal. (H. N. Lowe). 



Monterey, Cal., to Coronado Islands, Baja Cal., in 16-3 4 fms. 



1470 Epitonium (Crisposcala) Catalinse 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 stria? 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. 



Shell small, whitish, with a velvety pale olive periostracum 

 and SV 2 whorls; spire very short; suture very deep, not chan-
