aceous or brownish spots between the ri])s, surmounted by a con- 

 tinuous, cinnamon Hne. On the penult whorl this hne is median. 



Sculpture of vertical ribs weakening towards the base, the inter- 

 vals with short impressed lines in a spiral direction; on the last 

 whorl there are 11 ribs and about 19 spirals, exclusive of those on 

 the siphonal fasciole. On the penult whorl there are 10 or 11 im- 

 pressions in an interval. 



The aperture is slightly pink tinted within. Urate in the throat. 

 Five columellar plaits, the lower one very small. 



Length 25.3, diameter 8, aperture 12 mm.; 10 whorls. 



Off Waikiki, Oahu, in 200-300 feet. D. B. Langford. 



Mill a mter striata Sowerby (Thes. Conch, fig. 392) resembles 

 this species somewhat in co^or, h\ii it is wider, contracted more above 

 the more prominent siphonal fasciole, and has a wider aperture. 



Vexillum xenium n. sp. PI. XII, fig. 25. 



The shell is fusiform, white with a chestnut band traversed by 

 several paler spiral lines, below the periphery, two or three paler 

 interrupted lines above it on the summits of the ribs only, and a few 

 widely spaced blackish-brown spots below the suture, on the ends 

 of some of the ribs. The first three whorls are also deep brown. 

 Sculpture of smooth, longitudinal ribs, 22 on the last whorl, 

 equal to their interstices, the latter marked with short impressions 

 in spiral series, 6 on the penult whorl in each interval; base spirally 

 grooved over ribs and intervals forming about 4 spiral series of 

 tubercles. Two obliquely spiral cords are more prominent just 

 above the siphonal fasciole. Aperture shorter than the spire, the 

 throat with 9 thin beaded lirae. Columella with 5 thin plaits. 



Length 18, diameter 7.5, aperture 8.4 mm., 10 whorls. 



Off Waikiki, Oahu, 25-50 fms. D. B. Langford. 



Turricula approxima Pease (P. Z. S. 1860, p. 146) is described as 

 convexly angulated at the sutures and with 4 plaits; it seems there- 

 fore to be a different species. 



Vexillum micra a. sp. 



• 



The shell is fusiform, vinaceous tawny with a band at the peri- 

 phery and another on the base of burnt umber. Sculpture of many 

 vertical rounded ribs, about 30 on the last whorl, the intervals with 

 wide, low spiral cords separated by impressed lines, of which there 

 are 4 on the penult whorl; base with spiral cords. Aperture colored 

 like the outside. Columella with four plaits. The embryonic 

 shell is long-conic, of about 33^ smooth w^horls.
