Plate 46, fig. 5. 



Shell broadly elongate-conic, polished, bluish-white, excepting a 

 broad band of light chestnut brown, which encircles the turns cov- 

 ering a little more than half the spaces between the periphery and 

 the summit and extending for an equal distance over the base. 

 Early whorls rounded, separated by a well-impressed suture; the 

 succeeding turns moderately rounded, with very poorly impressed 

 suture, marked by faint lines of growth and an occasional almost 

 vertical varicial line, which is not accompanied by any brown mark- 

 ing. Periphery of the last whorl well rounded. Base produced, well 

 rounded. Aperture broadly ovate, somewhat patulose anteriorly; 

 posterior angle acute; outer lip thin; inner lip short, moderately 

 stout, curved, reflected over, and appressed to the base, except at 

 the extreme tip, where it is free; parietal wall covered with a thick 

 callus. 



The type and two specimens (Cat. No. 251395, U.S.N.M.) were 

 dredged by the United States Bureau of Fisheries steamer Albatross 

 at station 2902, in 53 fathoms off Santa Rosa Island, California, on 

 fine gray sand and mud bottom, bottom temperature 45°. The type 

 has 10 whorls and measures — length, 7 mm.; diameter, 1.8 mm.
