BELEMNITES abbreviate. 
TAB. DXC — figs. 2. 3. & 9. 
Spec. Char. Short, subcylindrical, with an ex- 
panded base ; extremity suddenly tapering 
and slightly recurved to a blunt excentric 
apex; sides flattened; cavity about half the 
length of the shell, its apex far from central. 
Syn. B. abbreviatus. Miller , Geol. Trans. 2d se- 
ries. p. 59. pi. VII. f. 9. & 10. De Blain- 
ville , Mem. sur les Belemn. p. 91. 
There appear to be no furrows upon any part of this 
shell ; its thickness in proportion to its length, the con- 
traction and curvature of its superior extremity, and the 
cavity inclining towards the front, are so many marks 
by which the species may be known. 
Occurs in the Inferior or Ironshot Oolite (probably 
only in the lower beds), and the upper beds of Lyas. 
Fig. 1. is from a Weymouth specimen : fig. 2. is from 
Banbury in Oxfordshire, by favour of the Rev. W. D. 
Conybeare ; it is part of an alveolus, and shows how 
closely the inflated tubes of the siphuncle between the 
septa approach the surface of the cavity, which in fact 
cuts off a segment from each. Fig. 9. represents a young 
individual of precisely the same form, from near Bath : 
it is in Mr. Goodhall’s cabinet. 
The figure referred to by Miller in Parkinson’s Org « 
Remains , does not decidedly represent this species.
