GASTEROPODA. 4) 
Museum, for information respecting it, and also for a careful drawing which exhibits its 
paleontological features ; the specimen was obtained in the Bradford Clay of the Tetbury 
Road Railway Station, near Cirencester, by Professor Coleman, of the Royal Agricultural 
College. 
Geological Positions and Localities. It has occurred at several localities in the Corn- 
brash, as at Wollaston, Chippenham, Trowbridge, and in Bedfordshire, but it is every- 
where rare; to these positions must be added the single specimen above alluded to from 
the Bradford Clay, and another, in the British Museum, from the slate of Stonesfield. 
GASTEROPODA. 
BracnytREMA varicosa, Lyc. Tab. XLIV, fig. 27. 
Testa parva ovata, gibbosa, spira anfractibus 5 subplanis, costis transversalibus et longi- 
tudinalibus inequalibus cruciatis ; granulatis, granulis magnis, depressis, ultimo anfractu 
varicibus irregularibus duobus ; apertura sinuosa, columella arcuata, canali breviusculo. 
Shell small, ovate, gibbose ; spire elevated, obtuse, consisting of five, flattened volutions, 
with well-marked sutural depressions; encircling coste five, of which the first and last 
are large, forming elevated bands, the three intermediate coste being smaller, irregular, 
and unequal; they are decussated by very irregular, granulated, straight costa, which 
occasionally form large varices, of which the last volution has two; these impart a distorted 
aspect to the lower part of the shell; the aperture is rather narrow and sinuated, the 
columella much curved, the canal short, the notch narrow and deep; the outer lip is 
thickened, but imperfect. 
A short, ovate shell, with strongly marked and very irregular ornamentation; the 
varices are prominent only upon the two latter volutions; the straight coste are very 
irregular, sometimes crowded, but occasionally very distantly arranged; the basal canal is 
unusually short, and curved forwards ; the lips are without denticulations. 
Geological Position and Locality. The Great Oolite of Minchinhampton Common ; very 
rare, two specimens. 
Bracuytrema BuccinoieEa, Lye. Tab. XLIV, fig. 17. 
Testa turriculata, ovali ventricosa, anfractibus 5—4 convevis, suturis valde impressis, 
longitudinaliter costatis, costis 14—16 rectis, transversim finissime lineatis, anfractu ultimo 
magno, rotundo, bast attenuato, canali brevi, obliquo ; apertura superne et inferne constricto. 
Shell turreted, ovately ventricose, volutions 5—4, convex, the sutures deeply impressed, 
longitudinally costated ; the costee, from 14 to 16 in a volution, are perpendicular, and not 
very strongly defined; they are decussated by fine, encircling lines; the last volution is
