ODOSTOMIA (EVALEA) PHANEA, new species. 



Plate XLVIII, fig. 7. 



Odostomia (Evalea) c/ouldi Dall and Bartsch, Mem. Cala. Acad., 1903, p. 282, 

 pi. I, fig. 15, not Odufitomia (? var.) gouldii Carpenter, Ann. Mag. Nat. 

 Hist., 3d ser., XV, 1865, p. 30 {=^Odostomia (Amaura) gouldl Carpenter, 

 of the present paper). 



Shell elongate-ovate, subdiaphanoiis to milk-white, stout and shin- 

 ing. Nuclear whorls small, deeply immersed in the lirst of the suc- 

 ceeding turns. Post-nuclear whorls rather high between the sutures, 

 well rounded with scarcely an indication of a shoulder at the summit, 

 separated by well-marked sutures. Periphery and the rather long 

 base of the last whorl well rounded. The first two whorls are regu- 

 larly closely spirally striated, in the third the striation becomes enfee- 

 bled and on the penultimate decidedly obsolete, while the base is 

 smooth. About 18 of the striae are visible on the third turn. Aper- 

 ture large, oval, somewhat effuse anteriorly; columella decidedly 

 curved and reilected, reenforced by the attenuated base, provided 

 with a strong oblique fold at its insertion. 



The type has 5 post-nuclear whorls and measures: Length 4.8; diam- 

 eter 2.0 mm. It and another specimen (Cat. No. 46408, U.S.N.M.) 

 belong to the Stearns collection and come from Monterey, California.
