obsolete on lower half of body- whorl; spiral sculpture consists of tliree or luiu liiuiaiscii lines on 

 lower portion of whorl and several microscopic linos on ujiper iiorlion; the s|)ir;il sculpture is more

Platk VIII, Fi.:. 1. 



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, elli[)tical, narrowing anteriorly to canal; canal truncate in front; 

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

DimcnsioJis. — Long. 12 mm.; lat. 4.2 mm.; boily-whorl .S mm.; aperture, including canal, 

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



Distingnishal)le by .slender form, evenly convex whorls, prominent transver.se 

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

 J/, oldroijdi in outline, but has no spiral sculpture or angulated whorls. Pronounced 

 a new species by Dr. Dall. Named in honor of jNIiss 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 tyi)e, which is from the lower San Pedro series of Deadman 

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

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