ODOSTOMIA (EVALEA) HAGEMEISTERI, new species. 

 Plate 26, fig. 1. 



Shell small, elongate ovate, yellowish white. Nuclear whorls small, 

 almost completely immersed in the first of the succeeding turns. 

 Post-nuclear whorls moderately well rounded, with rounded summits, 

 marked by retractive lines of growth and many fine, closely placed 

 spiral striations. Suture well impressed. Periphery of last whorl 

 well rounded. Base well rounded, marked like the spire. Aperture 

 ovate, posterior angle acute; outer lip thick within, thin at edge; 

 columella very short, very strongly curved, somewhat re volute, reen- 

 forced by the attenuated base and provided with a strong fold at its 

 insertion. 



The unique type (Cat. no. 159469, U.S.N.M.) was collected by 

 Dr. William PI. Dall at low-water mark at Hagemeister Island, 

 Bering Sea. It has five post-nuclear whorls and measures: Length 

 4.4 mm., diameter 2.4 mm. The fine spiral striations have been 

 omitted in the drawing. 



ODOSTOMIA (EVALEA) RESINA, new species. 

 Plate 27, fig. 6. 



Shell very small, vitreous, transparent. Nuclear whorls deeply 

 obliquely immersed in the first of the succeeding turns, above which 

 only the tilted edge of the last volution projects. Post-nuclear 

 whorls inflated, strongly rounded, decidedly contracted at the suture, 

 and appressed at the summit, where the preceding whorl is reflected 

 through it, and gives the summit the false appearance of having a 

 spiral cord. Suture strongly constricted. Periphery and base of the 

 last whorl well rounded. Entire surface of the shell marked by lines 

 of growth w hich are of varying strength, and numerous closely spaced, 

 exceedingly fine, spiral striations. Aperture ovate, posterior angle 

 acute; outer lip thin, showing the external sculpture within; col- 

 umella slender, strongly curved, shghtly revolute, reenforced by the 

 base, provided with a fold at its insertion. 



The type (Cat. no. 206925, U.S.N.M.) comes from Arch Beach, 

 California. It has five post-nuclear whorls and measures: Length 

 2.2 mm., diameter 1 mm.

Odostomia (Evalea) deliciosa Dall and Bartsch, Proc. U. S. Nat. Mus., vol. 33, 

 1907, pp. 525, 526, pi. 47, fig. 5. 



Shell small, elongate-conic, translucent to milk-white. Nuclear 

 whorls small, deeply immersed in the first of the succeeding turns, 

 above which only a portion of the last turn is visible. Post-nuclear
