from the Oxford Oolite. The ventral portion is to the dorsal as 40 to 60 ; the axis, as 
is usual in old specimens of hastate Belemnites, is not longer than in youth, and its 
proportion to the diameter is reduced to 240 : 100. 
These fossils appear, on the whole, most allied to Belemnites Tiastatus, Blainville, - 
and to the depressed variety of it which occurs in the Oxford Clay of England. But 
they are entirely distinct by the lateral grooves being so sharply cut over the alveolar 
and postalveolaf region, and by the absence of a ventral groove. 
There is, indeed, one specimen (the posterior part of a large guard) marked 
“ Upper Maranoa Eiver,” which, with portions of the lateral grooves, shows along the 
ventral face a partially impressed but interrupted groove, not unlike some appeai'ances 
of Belemnites sulcatus of the Oxford Clay of England. The lateral grooves show 
ramifications, and appear not to bend backward. It may be a different but allied species.

The Belemnites described * by Sir James Hector as B. australis, Phill., do not 
appear to belong to this species at all.

Sp. Char. Gruard hastate, with a rather long, very slightly undulating outline, 
ventral face flattened but without a trace of a ventral groove ; two lateral grooves 
sharply cut, and approximating to the ventral face in the alveolar region, thence bending 
towards the dorsal aspect with a scarcely perceptible curve and continued in a fine stria 
on the ventral margin. Length of preserved portion one hundred and forty-five milli- 
metres, width of the alveolar end twenty millimetres, greatest width at the end of the 
lateral groove, and about the centre of the fossil twmnty-two millimetres, ventro-dorsal 
width greatest at the broken end, and , gradually tapering thence to the point. {Ten. 
Woods.) 
Ohs. B. oxys differs from B. australis in its greater length, tapering outline, 
and different curvature of the lateral groove. Notwithstanding that it otherwise 
generally resembles the latter, the outline of the two species is so markedly different 
as to necessitate their separation, at any rate pending the discovery of intermediate forms.

Obs. Up to a comparatively recent date the only evidence of this Belemnite as 
an Australian species was the folloiving quotation from Mr. Moore’s Memoir. He 
states that two imperfect specimens were obtained from a Wollumbilla block and 
submitted to the late Prof. John Phillips, who stated that “ they belong to young 
Belemnites and show the phragmacone in situ, and the straight nearly central axis of 
the guard with a small canal. The cross-section of the phragmacone is distinctly 
elliptical and oblong ; the siphuncle is clearly enclosed ; longitudinal dorsal strise very 
distinct. I have made a sketch of these points, which on the whole make me adhere to 
the opinion of the Oolitic, and perhaps Liassic, affinity of this shell. It appears to be 
most nearly allied to B. paxillosus, but to be distinct by its elliptical phragmacone ; 
this ellipticity diminishes with age.”
