(D’Orb.) 
An elongated, smooth, somewhat fusiform Belemnite, somewhat compressed anteriorly 
and depressed posteriorly, terminating in a rather sharp point; marked throughout the 
whole length by a deep single uninterrupted furrow, slightly enlarged towards the point of 
the rostrum. Alveolar cavity occupying about a fourth of the length. There is some 
slight confusion respecting this species, which is undoubtedly the shell alluded to by 
Parkinson in the work above cited, and described by Miller as coming from the Stonesfield 
slate, near Woodstock. The specimens figured (PI. I, figs. 6—8), are from that locality. It 
appears also to be identical with the B. Flewriausus, D’Orb., which is found in the Great 
Oolite in the environs of Lucon (Vendée). We are further confirmed in this opinion by the 
fact that Professor Buckman has identified and figured, in the work above referred to, a 
Belemnite under the name of B. Flewriausus, as occurring in the Stonesfield slate of Glou- 
cestershire, which is identical with our shell from the same deposit in Oxfordshire, the 
latter being the original locality from which the species was first obtained. The con- 
fusion appears to have arisen from the English specimens having been confounded with the 
B. hastatus, Blainville (Hidolithes, Montfort), from the Oxford clay, at least it is so quoted 
by M. D’Orbigny ( Pal. Franc. Terr. Jur.’ p. 121), and also by Bronn (‘ Index Paleon- 
tolog.,’ p. 156), an opinion that Mr. Miller may possibly have induced, inasmuch as he also 
considered De Montfort’s species to be synonymous with the B. fusiformis.

B. Testa elongata, anticé compressa, postice depressd, subtus longitudinaliter sulcata, 
sulco posticé interrupto, aperturd compressa. (D’Orb.) 
An elongated, smooth, very slightly fusiform shell anteriorly compressed, posteriorly 
depressed, marked throughout the whole length by a furrow which is wider, and slightly 
divided towards the point.
