stolida occur together, and the former, tliough smaller, has 

 one whorl more in the spire. The three shells are no donbt 

 closely allied to each other. Eare, Table Cape. 



YoLUTA Tateana, n.s. 



Shell slenderly fusiform, of 8 whorls, including the 2 turns 

 of the smooth sharp pullus ; spire very acute ; apical angle 

 about 30 ^ ; whorls with regular sigmoid ribs, which become 

 somewhat obsolete downwards towards base of body whorl, 

 and upwards towards suture, but are raised into distinctly 

 angled tubercles, which form a spiral row near to the crown 

 of each whorl ; space between suture and row of tubercles 

 slightly concave, and iu distinctly marked with fine spiral 

 lirse ; tubercles slope abruptly upwards, and, with the ribs, 

 become obsolete near to the lip of aperture ; lip simple 

 emarginate above ; columella slightly curved, with 4 

 prominent oblique plaits; length 77mil., breadth 25mil., 

 leugth of aperture 42mil., proportional length of body whorl 

 y'VV, 8 of penultimate whorl y^V' P^'^P- ^i'- ^^ penult whorl 

 ^^^ ; shell finely striate longitudinally with lines of growth. 

 This shell has the general character of the last, but is readily 

 distinguished by its remarkably long slender appearance, 

 its larger number of whorls, and sub-central apex. Eare, 

 Table Cape. 



VOLUTA LIRATA, U.S. 



Shell ovately fusiform, shining, of 7 whorls, including the 

 smooth small pullus of 1| turns ; whorls scarcely convex, and 

 ornamented with fine slightly curved lirae, regular and 

 distinct above, but becoming indistinct and irregular on body 

 whorl ; the interspaces are marked with very fine longi- 

 tudinal lines of growth ; spire, with a slightly convex 

 outline, and forming an angle of about 50^ ; aperture 

 somewhat elliptical, longer than spire ; lip simple, emarginate 

 above ; columella curved, wdth 4 equi-distant distinct oblique 

 plaits ; length of shell 48mil., breadth 21mil., length of 

 aperture 30mil., proportional length of body whorl ^^^^^ of 

 penult, whorl ^^n^. This shell approaches closely to V. 

 McCoyi, but is lirate, larger and more ventricose. 



YOLTJTA AgNEWI, U.S. 



Shell very small, narrowly fusiform, of 6 regularly 

 increasing whorls, including smooth pullus of 1| turns, with 

 pointed sub-central nucleus ; spire very acute, with a some- 

 what blunt apex ; apical angle 30 *^ to 35 ^ ; whorls 

 ornamented with 9 or 10 ribs, which become raised near the 

 centre with a row of blunt tubercles ; ribs on body whorl 

 become obsolete towards the base ; surface of shell finely 

 cancellated, the transverse spiral lines being most con-
