BARLEEIA DALLI, new species. 



Plate 13, fig. 10. 



Shell rather large, broadly conic, yellowish white. Nuclear whorls 

 two, well rounded, marked by sinuous axial rows of closely spaced 

 pits, which are separated by spaces about four times as wide as the 

 pits. Postnuclear whorls almost api:)ressed at the summit, moderately 

 rounded, marked by slender, slightly retractively slanting incre- 

 mental lines and numerous closely spaced spiral striations. Suture 

 but slightly constricted. Periphery of the last whorl marked by a 

 cord, which renders it decidedly angulated. Base moderately long 

 and moderately rounded, marked like the spire. Aperture subcir- 

 cular, posterior angle obtuse; outer lip thin at the edge; inner lip 

 slender, evenly curved, appressed to the base, except at the extreme 

 anterior portion, where it is free; parietal wall covered by a thick 

 callus, which joins the columella with the outer lip at the posterior 

 angle and renders the peritreme complete. The summit of the last 

 turn bends slightly down below the peripheral cord near the aper- 

 ture. 



The type and 49 additional specimens. Cat. No. 209013, U.S.N.M.. 

 were dredged at the Bureau of Fisheries Station 4310 in 71 to 75 

 fathoms on sand and mud bottom, off Point Loma, California. The 

 type has six and one-quarter Avhorls and measures — altitude, 4.4 

 mm.; diameter, 2.4 nun. 



BARLEEIA BENTLEYI, new species. 



Plate 13, fig. 2. 

 Shell small, conic, flesh colored, excepting the two nuclear turns, 

 which are light brown. Nuclear whorls well rounded, marked by 

 curved axial rows of closely spaced pits, which are separated by 

 spaces about one and a half times the diameter of the pits. Post- 

 nuclear whorls moderately well rounded. The appressed summit of 

 these whorls falls slightly below the peripheral keel, and allows this 

 to appear in the suture as a slender thread. The surface of the post- 

 nuclear turns is marked by curved incremental lines and numerous 

 fine, rather closely spaced, spiral striations. A strong cord marks 

 the periphery and renders it decidedly angulated. Base moderately
