Description of some New Species of Fossil Shells. 103 
Genus Votuta.—Linneus. 
; V.-dubia. Pl. 1, fig. 23. 
Y. testa fusiformi, crassa, longitudinaliter sulcata, striis trans- 
versis minimis; spira valdé elevata, mammillata; anfractibus sep- 
tenis, planulatis; suturis minimis; columella quadriplicata ;_pli- 
cis inferioribus zequalibus superioribus; apertura angusta. 
Shell.fusiform, thick, with very small transverse lines, longi- 
tudinally sulcate ; spire very elevated, mammillate ; whorls seven, 
flat; sutures very small; columella with four folds, the lower 
ones equal to the upper ones; mouth narrow. ~ 
Length ‘7. Breadth -35 of an inch. 
Remarks.—T he sulcations become more strongly marked upon 
the last whorl. ‘It is with some doubt, that I place this singular 
shell among the Volute, to which genus, however, it seems to 
belong, from its mammillated apex ; its general form, however, is 
that of a Mitra, while the folds on the columella are between the 
two, being all equal.* The mouth is only half as long as the shell, 
instead of extending nearly from the apex to the base, as in most 
Volute, Mr. Conrad has described two species of Mitra from 
Claiborne, the M. pactilis and M. bolaris, which, as they have 
Mammillated spires, seem to me rather to belong to the Volute. 
FAMILY CONVOLUTA. 
Genus Conus.—Linneus. 
C. parvus. Pl. 1, fig. 24. 
C. testa conica, levi, polita, crassa; anfractibus , planula- 
tis, superné et transverse striatis, longitudinaliter et oblique plica- 
tis infra angulatum ; suturis parvis ; basi striata ; apertura angus- 
tissima, 
Shell conical, smooth, polished, thick ; whorls , flat, trans- 
versely striate above, longitudinally and obliquely folded below 
the angle ; Sutures small; base striated ; mouth very narrow. 
Length Breadth 12 of an inch. sys 
Remarks.—Phis little shell has nothing remarkable about it, 
©xcept its folds near the shoulder, which, together with its small 
Size, distinguish it from the C. sauridens of Conrad.

The distinction between Mitra and Voluta is thus drawn by Lamarck, Ani- 
iat sans Vert. Vol. vi, part 1, p. 328. “C'est avec les Mitres que'les Volutes ont 
5 Plus de rapports; mais elles en sont éminemment distinguées : 1, par les plis de 
ere! columelle dont les inferieurs sont les plus gros ét les plus obliques; 2, par l'ex- 
mité de leur spire qui est obtuse ou en mammélon.”
