ODOSTOMIA (EVALEA) FERNANDINA, new species 



Shell moderately large, elongate-ovate, milk white. Nuclear whorls 

 immersed in the first of the postnuclear turns, above which the tilted 

 edge of the last volution projects. Postnuclear whorls narrowly 

 shouldered at the summit, almost flat, marked by incremental lines 

 and very fine spiral striations only. Suture quite strongly constricted. 

 Periphery of the last whorl well rounded. Base long, attenuated, wel! 

 rounded, marked like the spire. Aperture fractured, apparently oval; 

 posterior angle acute; outer hp thin; inner lip stout, reflected over 

 and ap pressed to the base for almost its entire length as a heavy callus; 

 a rather strong callus covers the parietal wall.

ODOSTOMIA (EVALEA) HYCLEA, new species 



Shell of medium size, elongate-ovate, yellowish white. Nuclear
