obsolete on lower hall" of body-vvhorl; spiral sculpture consists of three or four fine raised lines on 

 lower portion of whorl and several microscopic lines on upper portion; the spiral sculpture is more 

 prominent on the body-whorl; suture deeply impressed; aperture narrow p)'riform, drawn out on 

 anterior end to a long, narrow, recurved canal; outer lip arcuate, thin, simple; inner lip smooth. 



Dimensions. — Long. 16 mm.; lat. 6 mm.; body-whorl 10 mm.; aperture 8 mm.; defl. 

 38 degrees. 



The largest and finest of the Pleistocene MnngUve. Distinguishable by its 

 large size, rounded ridges, faint shouldered appearance of the whorls, and long, 

 recurved canal. " Different from any of the species in the Smithsonian collec- 

 tion " (Dall). 



Rare in lower San Pedro series of Deadman Island; one specimen (ty[)e) 

 collected by Mrs. Oldroyd, which is figured, and is now in her collection. 



Pleistocene. — San Pedro (Oldroyd).

Shell small, elongate-fusiform; spire elevated; apex rounded; whorls seven, evenly convex, 

 with about eleven slightly transverse, rounded ribs, which become obsolete at the sutures; spiral 

 sculpture obsolete; aperture narrow, elliptical, narrowing anteriorly to canal; canal truncate in front; 

 posterior sinus small; outer lip arcuate, thin, with faint ridge on interior; suture deeply impressed ; 

 pillar long, smooth within, obsolete sculpture without. 



Dimensions. — Long. 12 mm.; lat. 4.2 mm.; body-vvhorl S mm.; aperture, including canal, 

 6.1 mm.; canal 1.5 mm.; defl. 32 degrees. 



Distinguishable by slender form, evenly convex whorls, prominent transverse 

 ribs, and obsolete spiral sculpture; canal also longer than in most species. Resembles 

 7)/. oldroydi in outline, but has no spiral sculpture or angulated whorls. Pronounced 

 a new species by Dr. Dall. Named in honor of Miss Winifred Mabel Paine of Red- 

 lands, California, who has drawn many of the figures illustrating this paper. 



Not uncommon in the lower San Pedro series of Deadman Island. The 

 specimen figured is the type, which is from the lower San Pedro series of Deadman 

 Island, and is now in the United States National Museum. 



Pleistocene. — San Pedro (Arnold).

Be/a sculpturata Dall, Proc. U. S. Nat. Mus., Vol. IX, 1887, p. 299, PI. IV, fig. 7. 



Shell small, turreted, elongate- fusiform; apex acute; whorls seven, sharply angulated, with 

 flat, sloping surfaces both above and below angle; sculpture consists of eight or nine sharp transverse 

 ridges, and two or three sharp spiral lines on lower portion; aperture very deeply impressed, giving 

 tabulate appearance to whorls; aperture long, narrow, and drawn out into a long, narrow canal at 

 anterior end; outer lip thin, simple; inner lip smooth; spiral sculpture extends to base of pillar. 



Dimensions. — Long. 10.5 mm.; lat. 3 mm.; body-whorl 6 mm.; aperture 4 mm.; defl. 

 23 degrees.
