The type (Cat. No. 46492, U.S.N.M.) is from Monterey, has 6i 

 post-nuclear whorls and measures, leng-th 4 mm., diameter l.i) mm. 

 Another specimen (Cat. No. 1963U1, U.S.N.M.) also comes from Mon- 

 terey, California. 



ODOSTOMIA (EVALEA) TACOMAENSIS, new species. 

 Plate XLVIl, fig. 10. 



Shell ovate, yellowish. Nuclear whorls small, deeply immersed in 

 the first of the succeeding turns. Post-nuclear whorls well rounded, 

 faintly roundly shouldered at the extreme summits. Periphery of the 

 last whorl rounded. Base inflated, well rounded, somewhat attenuated 

 anteriorly. Surface covered by numerous equal and equally closely 

 spaced slender wavy spiral striations of which there are about 40 

 between the summit and the periphery of the last whorl. Base marked 

 like the space posterior to it. In addition to the spiral sculpture the 

 entire surface of the shell is crossed by numerous fine lines of growth. 

 Aperture moderately large, oval, well rounded anteriorly; posterior 

 angle acute; outer lip thin; columella curved, slightly reflected, 

 reenforced, except at its extreme anterior end, by the attenuated base 

 and provided with a strongly oblique fold at its insertion. 



The type (Cat. No. 159267, U.S.N.M.) has 5 post-nuclear whorls, 

 and measures: length 4.3 mm., diameter 2.5 mm. It was collected by 

 Mr. Fisher at Tacoma, Washington. 



ODOSTOMIA (EVALEA) VALDEZI, new species. 

 Plate XLVIII, %• -■ 



Shell small, thin, very elongate-oval, subdiaphanous to milk-white, 

 having the entire surface marked by rather strong lines of growth 

 and numerous microscopic spiral striations. Nuclear whorls deeply 

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

 only the tilted edge of the last turn is visible. Post-nuclear turns 

 rather high between the sutures, well rounded, with narrowly roundly 

 shouldered summits. Periphery and base of the last turn inflated and 

 well rounded, the latter with a very narrow umbilical chink. Aper- 

 ture moderately large, oval; posterior angle acute; columella strongly 

 curved, reenforced ])y the attenuated base and provided with a moder- 

 ately strong fold opposite the umbilical chink. 



The type has 5 post-nuclear whorls, and measures: length 3 nnn., 

 diameter 1.3 mm. ltandanotherspecimen(Cat. No. 196249, U.S.N.M.) 

 were collected by Mr. S. S. Berry in 12 fathoms, off Del Monte, Mon- 

 terey, California. Two additional specimens from the same station 

 are in Mr. Berry's collection.
