are smooth, the following IVi whorls are sculptured with 

 widely spaced grooves. The varix terminating the nepionic 

 stage is at the end of 2y 2 to 3 whorls. The 'adult sculpture is 

 of flatly rounded rib-striae parted by narrower grooves and 

 about 5 in a mm. on the last whorl. The columella is straight, 

 obliquely truncate at base. The outer lip is very lightly 

 arched forward, and there is a minute point or callous drop 

 on the white edge, at its lower third. 



Length 23, diam. 6.4, aperture 8.8 mm., whorls 7 1 /. 



Length 18.2, diam. 5.9, aperture 8.5 mm., whorls ft 1 /?. 



Some ispeclmens from Yallahs Hill are very pale buff with 

 the brown streaks emphatic above, tapering and paler down- 

 wards. 24 x 7, ap. 9.9 mm., whorls l l / 2 - Those from other

"Shell much elongated, oblong- fusiform, not very shin- 

 ing, often semi-pellucid, of a brown color, deeply-tinted with 

 rose orange; with narrow dark, reddish-hued or chestnut 

 transverse streaks, crossing completely over all the whorls 

 but not always extending to the base of the last whorl, but 

 always coincident with and bordering the varices, of which 

 there a.re four to five upon each whorl. Shell sculptured 

 with fine transverse striae, which become more apparent on 

 the upper shoulder of the body whorl, next to the suture. 

 Whorls 7, slightly convex, but in most cases perceptibly flat- 

 tened or 'constricted at the periphery; the last whorl more 

 than one-half the entire length of the shell. Suture im- 

 pressed, the edge somewhat 'crenulated ait one margin by the 

 intrusion of the transverse strise. Spire with the outlines 

 somewhat curvilinear, rather pointed at the summit. Aper- 

 ture not large, semi-ovate ; labrum sharp, slightly produced 

 towards the middle and below that point, gradually retreat- 

 ing, expanding and rounding off to meet the twisted, arcuated 

 and obliquely truncate columella. Length 23 to 25, greatest 

 diam. 7, or slightly less. Length of aperture 9, largest diam. 

 4 mm. ' ' ( Vendryes") .
