Ois. The following remarks were made by Mr, Etheridge : — With the exception 
of being more elongated than the shell described by Dr. E. Stoliezka, our shell appears 
to be the same, allowing for those Yariations which the species in this genus exhibit. It 
is not so ventricosc a shell as I. striafus, Mant., from the Lower Chalk of Sussex, Saxony, 
&c. (^Etheridge.') 
I fail to detect any direct resemblance between the figure of this biyalve and that 
of Stoliezka’s J. imiltiplicaiiis* It will possibly simplify matters if it be known under 
its varietal name, elevated to specific rank, until more definite characters can be assigned 
to it than those quoted above. 
The peculiarity of the concentric folds removes it from I. prollematicus (D’Orb.) ; 
and as regards I. multiplicahis, it differs wholly in shape.

Ohs. Several examples of an obliquely-oval oblong Inoceramus have been 
collected by Mr. S. Sharwood at Aramac Well, with coarse, distant, regular, and even 
corrugations, which I cannot with any degree of accuracy separate from this world- wide 
species, known as it is from Europe, India, and America (Texas). 
Tlie individuals are constant in size and shape, possessing a stronger resemblance 
to Prof. Zittel’s excellent figures than they do to Stoliezka’s of the Indian variety. We 
observe the straight hinges, oblique-oval form, prominent anterior, and almost terminal 
heaks, and the same angular, concentric, sometimes fluctuating corrugations, with inter- 
mediate finer stria;. The only difference which can be detected is the smaller and deeper 
anterior end, but, as I have not succeeded in entirely relieving a specimen from the matrix, 
the latter, and verified examples of I. Gripsii, cannot be compared in this direction. 
There also exists a resemblance to Inoceramus proximus, Meek,t more especially 
in the smaller anterior end ; and a further comparison may be made with Inoceramus 
prollematicus, var. aviculoides, Meek.J 
A small form of Inoceramus has been met with in a boring at Muttaburra. The 
outer shell has been removed, and the outline is not entire, but there are still traces of 
the usual corrugations. This may be the decorticated condition of Inoceramus Gripsii. 
It is certainly after that type.
