22 MOLLUSCA FROM THE GREAT OOLITE. 
Auaria PARVULA. Plate III, fig. 12¢, 120. 
A, Testi parva, turritd ; anfractibus quinque convexis, angustats, levibus, ultimo planato, 
striato; striis transversis, crebris, acutis, subcrenulatis ; caudd brevissimd ; alé—? 
Shell small, turreted, volutions (5) convex, narrow, smooth, the last volution flattened, 
striated, striz transverse, closely arranged, acute, and slightly crenulated ; the canal nearly 
obsolete ; wing unknown. 
Locality. The planking of Minchinhampton Common has furnished only one well- 
preserved specimen with which we are acquainted,—it does not exceed 6 lines in length; 
the whorls are very narrow and convex, the striz being visible only upon the body whorl.

Prerocera cirrus, D’Orb. 1850. Prod. Paléont., p. 302. 
A. Testa turritd, transversim striata, apice acuminato; anfractibus medio carinatis, ultimo 
inflato, bicarinato ; carind superiori eminentiori, gibbum transverse oblongu ori oppositum 
gerenti: ald brevissimd, in etate juniori monodactyla, deinde (@tale proyredient:) didactyld, 
digitis longis, divaricatis, tenuibus, trigonis. Cauda longissimd, recta, apice tacurvo, 
(Deslongchamps.) 
Shell turreted, apex pointed, transversely striated, whorls carinated m the middle, the 
last whorl inflated, having two carme; the first carina bemg the most prominent. A 
transverse prominence is placed opposite to the aperture; the canal is long and straight; 
except the extremity, which is curved. 
A single specimen, in which the last whorl is imperfect, is all we have to refer to; the 
form, however, is unequivocal; the spire is unusually short and ventricose, as compared 
with other examples of the genus, and in the stage of growth which our specimen exhibits, 
had not acquired the large digitations and caudal extremity proper to a later period. 
Locality. Minchinhampton Common ; it must be referred to some of the shelly beds 
beneath the planking; rare. Great Oolite, Ranville, Normandy.  (Des/.) 
Family—MvRIciv&. 
Fusus, Zam. 1801. 
Shell fusiform or subfusiform, ventricose in the middle, with an elevated spire, volutions
