PURPURINA (EUCYCLOIDEA). o7 
angulatus, Miinst. (‘ Goldf. Petref.,’ t. 194, f. 5), a fossil of the Murchisone-zone iden- 
tified by Oppel with P. patroclus, D’Orb. (‘ Ter. Jur.’ 2, pl. 329, figs. 9—11). As 
a temporary name I propose that our shell be called “* Purpurina fusiformis.” It 
belongs to the Woodwardian Museum, and is marked * Yeovil.” Hence I presume 
it is a fossil of the Lower Division of the Inferior Oolite.

Description —* Shell small, fusiform; spire of four volutions, keeled and 
striated; an elevated carina encircles the middle of each whorl, its edge undu- 
lated or crenulated; encircling strive cover the whole surface of the shell, and there 
is an indistinct circle of nodules upon the upper portion of each whorl near the 
junction.” —Lycerr. 
The specimen now figured answers to the above description, except that 
possibly the spire may have had five whorls. It evidently belongs to the same 
section of Purpurina as P. bianor, but obviously differs in the smaller spiral angle, 
and in possessing a more defined base (not well shown in Fig. 7 a, b) ; in fact, the 
body-whorl may be regarded as distinctly bicarinate. The character, though not 
the details of the ornamentation, are similar. With ‘“ P. fusiformis” it has closer 
affinities, but the Cotteswold shell is much feebler. 
This specimen is from the Lycett Collection in the Jermyn Street Museum, 
and is the only one known to me. The author quotes the species from the 
Inferior Oolite of Minchinhampton (op. cit., p. 73). 
Some other small fossils from the Inferior Oolite have lately turned up which 
may belong here, but at present it seems safer to reserve these to be dealt with 
subsequently, either by way of postscript or otherwise. 
Genus—Bracuytrema, Morris and Lycett, 1851, Great Ool. Moll., p. 24. 
« Shell small, twisted, turbinated, solid. Whorls nodular, costated or cancellated ; 
the last whorl large and ventricose ; columella smooth, rounded ; twisted near to 
the base, and reflecting outwards, forming a short oblique canal; aperture moderately 
subovate, less frequently thickened, and externally subvaricose.’’—Fiscurr, ‘ Man. 
Conch.,’ p. 685.
