Fulgnrarin.'] GASTROPODA. 449 



with 4 plaits. Sculpture : The protoconch has 1 or 2 spiral threads ; 

 the following whorls of the spire are distantly axially costate, the 

 costse extending over the lower two-thirds of each whorl, 10 on a 

 volution ; a few costse are situated on the body above the aperture, 

 but the remainder is smooth ; growth-lines are visible on all the whorls, 

 more distinct and close together on the last whorl ; with a lens a 

 number of spiral lines may be distinguished below the shoulder of the 

 whorls. Colour : No live specimens having been obtained, it is im- 

 possible to guess the colour of the shell, which is most likely light 

 fulvous ; fine longitudinal brown zigzag lines ornament all the whorls, 

 except the protoconch. The spire is much shorter than the aperture, 

 conical, acuminate jput obtuse. Protoconch consists of 2 slightly 

 bulbose whorls ; the nucleus is slightly lateral, smooth ; the second 

 whorl has one or two spiral threads. Whorls 7, shouldered, first slowly 

 then rapidly increasing in height. Suture distinct, but not impressed, 

 retrocurrent on reaching the aperture. Aperture high and narrow, 

 slightly canaliculated at the upper angle, very little narrowed at the 

 base, where it is broadly truncated and sinuated. Outer Up forming a 

 very light curve, nearly straight, thickened and rounded above, thinner 

 near the base, smooth, not expanded. Columella very slightly ex- 

 cavated near the middle, with 4 almost equidistant and very oblique 

 strong plaits, all of nearly equal size, narrowed below into a sharply 

 rounded beak, which extends beyond the basal margin of the outer 

 lip. Inner lip thin, shining, broadly expanded on the body, and with 

 a few longitudinal striae, narrower upon the pillar.

Shell fusiform, strongish, pale buff, with high blunt spire, largish 

 aperture, slightly reverted outer lip, and 4 teeth on the pillar. Sculp- 

 ture : On the upper whorls there are a few slight narrow axial ribs, 

 which are almost obsolete on the later whorls ; the lines of growth 

 are many and hair-like. The columellar swelling in front is very 

 small and slight. Colour ashy-white over pale buff, entirely without 

 gloss, the outer lip and the body-glaze are rich buff, paler inwards. 

 Spire high, a little irregularly bent, subscalar, its height two-thirds 

 of that of the aperture. Protoconch blunt, mamillary, impressed. 

 Whorls 6J ; they are convex, above contracted into the suture, per- 

 pendicular below ; after the first three they increase rapidly ; the
