of low, rounded vertical ribs, somewhat unequal, and parted by 

 narrow furrows; there are about 24 such ribs on the penult whorl; 

 also very few swollen varices, in the type three: on the left side of 

 the last whorl, on the third, and on the sixth whorls above the last. 

 Over ribs, intervals and varices there are seven low spiral cords, 

 much wider than their intervals, on each whorl to the last, which 

 has 17, the lower cords being narrower there. The aperture is 

 trapezoidal; outer lip simple; columella straight, vertical, having a 

 small, steeplj^ ascending spiral fold near the base. It joins Avith the 

 basal margin in a rather small curve, but there is no angle at the 

 junction. 



Length 15.5, diam. 4 mm.; aperture 3.3 mm. long; 13 post- 

 embryonic whorls. 



Viti Islands. Type and 2 other specimens are No. 20046, 

 A. N. S. P., collected by A. J. Garrett. 



Several lots sent by Mr. Garrett at different times show this to be 

 rather constant in size and other characters. There are usually two 

 distinct and often one small varix. The name vitiensis was used on 

 one of Garrett's labels, but I cannot find that he published it. 

 Turbonilla vitiensis clavus n. subsp. PL XXII, fig. .3. 



The shell is similar to T. vitiensis except that it is more slender; 

 penult whorl with 20 vertical ribs. 



Length 12.5, diam. 2.9 mm.; length of aperture 2.5 mm.; 13 post- 

 embryonic whorls. 



Viti Islands. Type No. 117597, A. N. S. P., collected ])y A. J.

 Odostomia (Odostomella) patrioia n. sp- Fig, ii. 



Waikiki beach, near Honolulu. Type No. 93944, A. N. S. P., 

 collected by Frederick Stearns. 



The shell is oblong, solid, white, the last whorl encircled with 

 three cinnamon bands, two of which are visible on the penult and 

 one on the preceding whorl. The nuclear whorl is rather well 

 elevated, smooth. Subsequent whorls have rounded axial ribs as 

 wide as their intervals, about 20 on the last whorl, where they con- 

 tinue over the base, though weaker below. Lender a high power 

 some weak spiral striation is visible on the base. The suture is 

 narrow and rather deeply impressed. The aperture is rather nar- 

 rowly ovate, oblique. Columellar fold small. 



Length 1.6, diam. 0.7, length of aperture 0.55 mm.; 4| whorls. 



This species is smaller than 0. doliolum, with narrower ribs, l>ut 

 much the same coloring.
