ACTEONINA PARVULA, D’Orb. 1850. Prod. Paléont., p. 353. 
A. Testé parva, ovato-conicd ; anfractibus (4) subconvexis superioribus, lateribus sub- 
planis ; apertura integra elongatd, basi angustatd, columella contorta. 
Shell small, ovately conical; whorls (4) rather convex upon their upper portions, but 
flattened upon their sides ; aperture entire, elongated; base narrow; columella twisted. 
This little shell varies much in the length of the spire, specimens with narrow whorls 
having a greater degree of convexity at their upper part than the others, but in all of them 
the spire is shorter than the last volution. The largest specimens have an axis of 4 lines, 
and a transverse diameter of nearly 3 lines. 
Locality. Minchinhampton. It is found not unfrequently in all the quarries of the 
district, and is common to the shelly beds. 
AcT£ONINA? BuLIMorpDES. Plate VIII, fig. 15. 
A. Testé ovato-elongaté, levi; spird elatd obtusa; anfractibus (3—4) subconvezis, 
anfractu ultimo subcylindrico ; aperturd ovata ; labro sinistro incrassato. 
Shell ovately elongated, smooth, with an obtuse elevated spire; whorls (3—4) some- 
what convex, the last whorl subcylindrical; aperture ovate; inner lip thickened but not 
broad. 
The general figure is pupzform; the aperture in length does not exceed half that of 
the entire shell. 
This species has been provisionally arranged under <Acfeonina, although-the great 
thickness of the shell and expanded columellar lip do not well agree with that genus, and 
rather approximate it with Budimus. In general form it is very near to the Chemnitzia 
Cornelia, D’Orb., ‘Terr. Jurass,’ t. 245, figs. 2, 3, from the Coral Rag of France ; and 
both species may hereafter be found to belong to a genus distinct from Chemnitzia and 
Acteonina. 
Locality. Minchinhampton. ‘The specimen figured is the only example which has 
come to our knowledge. The exact bed from which it was obtained is rather doubtful; 
but, judging from the matrix to which it is attached, we should infer that its position was 
probably the upper portion of the Great Oolite.
