 smooth. About IS of the strife are visible on the third turn. Aper- 

 ture larjje, oval, somewhat effuse anteriorly; columella <lecidedly 

 curved and reflected, reenforced l)y the attenuated base, provided 

 with a strono; oblique fold at its insertion. 



The ty})e has five post-nuclear whorls and measures: Length 

 4.8 mm., diameter 2.6 mm. It and another specimen (Cat. no. 46408, 

 U.S.N.M.) belons; to the Stearns collection and come from Monterey, 

 California.

 Plate 23, %. 9. 



Shell ovate, vitreous, translucent. Xudear whorls deeply, verv 

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

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

 whorls inflated, shghtly contracted at the suture, appressed at the 

 sununit, marked by 8 strongly incised spiral lines on the first and 

 second and 20 upon the third, between the sutures. Suture well 

 marked. Periphery and base of the last whorl well rounded, marked 

 by numerous spiral striations, wliich are a httle weaker than those 

 between the periphery and summit of the last whorl. Aperture oval; 

 posterior angle obtuse; outer hp thin; columella moderately strong, 

 decidedly curved and strongly re volute, provided with a strong fold 

 at its insertion. 



The type (Cat. no. 196348, U.S.N.M.) comes from San Pedro Bay.

ODOSTOMIA (EVALEA) SANTAROSANA, new species. 



Plate 2(j, %. (i. 



Shell elongate-ovate, light olive. Nuclear whorls very deeply 

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

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

 whorls much broader at the moderately constricted suture than at 

 the feebly shouldered summit; well rounded. The first 4 are 

 marked by strongly incised spiral lines, of which 7 occur upon the 

 second, 10 upon the third, and 13 upon the fourth, of which the 5 

 immediately below the summit are finer and closer spaced than the
