There is a similar pink form with roseate apical whorl, which 

 may be called var. rosa, and another form, similarly colored, with 

 only about 16 larger ribs on the last whorl and having the nuclear 

 whorl larger; it may be named var. rhodocephala.

Odostomia (Chrysallida) stearnsiella n. sp. Fig. n. 



Waikiki beach, near Honolulu, Oahu. Type No. 93931, A. N. 

 S. P., collected by Frederick Stearns. 



The shell is ovate-conic, solid, white. Nuclear whorl regular, 

 well raised, the apex turned in; two or three following whorls have 

 weak axial folds. All of the post-nuclear whorls have narrow spiral 

 furrows; on the last whorl there are four above the periphery, the 

 upper one widest, and after a peripheral smooth zone the base has 

 about 6 weak spiral cords. The aperture is ovate, the columellar 

 fold strong. 



Length 3.5, diam. 1.4, length of aperture 1.3 mm.; 5| post-nuclear 

 whorls. 



Odostomia (Miralda) syrtites n. sp. Fig. 12. 



Waikiki beach, Oahu. Type No. 93934, A. N. S. P. 



The shell is ovate-conic, white. Nuclear whorl smooth, somewhat 

 elevated, the apex depressed. Following wliorls of the spire having 

 a broad raised zone, indistinctly bipartite, bearing somewhat oblique 

 ribs; this is followed by a spiral sulcus and a stout smooth spiral 

 ridge. On the last whorl the depression dividing the upper zone is 

 deeper; there are about 26 oblique ribs. From the periphery down 

 there are about seven spiral ridges, the last three quite weak. The 

 aperture is ovate, oblique. Columellar fold strong, rather thick. 



Length 1.7, diam. 0.95, length of aperture 0.65 mm. 4| whorls 

 in all. 



There are more basal keels than in 0. scopulorimi Watson, and the
