66 MOLLUSCA FROM THE GREAT OOLITE. 
T. Testé turbinato-conicd, acutd, lineatd; basi granulatd cingulatd; anfractibus (6) 
subteretibus bicarinatis, carinis granulis erectis coronatis; interstitis canaliculatis. 
Shell turbinated or conical; apex acute, the base with a granular band encircling it ; 
the whorls (6) are turreted, and have two encircling carine, the carme are elevated and 
frmged with closely-arranged granules, the interstitial spaces are canaliculated. 
Locality. ‘This elegant species occurs rarely in the planking of Minchinhampton 
Common ; it is usually crushed or otherwise imperfect ; it occurs hkewise in the Inferior 
Oolite of Gloucestershire more frequently, and is usually better preserved. 
We have ventured to assign this shell to the species described by Goldfuss, although 
its state of preservation does not show the longitudinal markings characteristic of that 
species.

T. Testé parvd, conicd; spird obtusa; anfractibus (4) planatis, ultimo superne sub- 
concavo, inferne convexo, striis crebris, subundatis, transversis cincto; apertura ovata; 
umbilico nullo. 
Shell small, conical; spire obtuse; whorls 4, their sides flattened, the last whorl 
slightly concave in the upper and convex in its lower part; the whorls are encircled with 
strize, closely arranged and slightly undulated ; aperture ovate; no umbilicus. 
In this minute species, the junctions of the whorls are strongly marked ; the striz are 
slightly punctated, giving to the spaces between them a rough or scabrous aspect ; the 
strize, however, are but faintly impressed, and are scarcely visible upon some specimens ; 
the substance of the shell is thick, its axial slightly exceeding its transverse diameter, or 
being equal to about 2 lines. 
Locality. Minchinhampton Common and Bussage. At both places it is somewhat 
rare, but occurs in more than one shelly bed. Ancliff, Wiltshire.

T. Testé conoided, spird elatd, acutd; anfractibus (5) planatis et costatis ; costis trans- 
versis (4) densé nodulosis; aperturd ovatd, subdepressd, umbilico nullo. 
Shell conoidal, spire elevated, acute; whorls (5) flattened and costated ; the coste 
(4 in number) are transversal, and densely nodulated ; the aperture is ovate and somewhat 
depressed ; and there is no umbilicus. 
The length of the aperture is scarcely equal to half the entire length of the shell, and
