Tur r i s e 11 siner en si s , new sp. 



PI. 2 Pig. 3 and 4. 



Shell email, fusiform, spire high, apex unknown, whorle 

 four to five present; angulated near suture, shoulder concave, 

 whorls slightly convex below angle, body whorl evenly convex; 

 longitudinal sculpture eleven to twelve prominent rounded 

 ridges which slope slightly to the left, and are most prominent 

 on upper part of whorl near angle, but are not present on the 

 shoulder; shell spirally marked by two to three lines above and 

 seven to eight lines below angle; body whorl and columella 

 ornamented by twenty five spiral lines which are sometimes sub- 

 equal and alternating; aperture narrow, outer lip thin and 

 smooth, prominently reflected; posterior sinus deep along 

 suture, anterior edge of the sinus parallel to the line of 

 angulation; canal short curved slightly backwards from the 

 aperture; columella smooth. 



This species is close to Turris coalingensis, from which 

 it differs by having spiral lines infer and more numerous, and 

 no difference in coarseness of sculpture on body whorl and on 

 columella. It differs from Mangilia tabulatus as figured by 

 Arnold from Bath-House Beach, Santa Barbara, by finer spiral
