Specimens from Marble Creek, (no. 42 on locality map.) 
The fossiliferous rocks from Marble Creek are numbered 78-99. 
Lithological Characters .—Nos. 78 to 95 are pale grey to dark blue 
limestones, chiefly composed of the remains of crinoids, but occasionally 
containing fossils of a very interesting nature. This limestone appears to 
be generally compact, and, as it takes an excellent polish, would form a 
valuable marble for ornamental purposes. 
Nos. 96 to 99 are more or less of the nature of ferruginous shell-grits 
and conglomerates, with included fragments of pebbles^ of shale and 
ovoid pellets of igneous origin. 
Mr. Kitson reports that the fossiliferous conglomerate beds at Marble 
Creek overlie the crinoidal limestones.

This limestone is almost entirely composed of the 
stems and ossicles of crinoids. In thin slices a 
spine of (?) Palee echinus, ostracoda, polyzoa (fenes- 
tellids) and a fragment of a fistuliporid, were ob¬ 
served. The organic fragments are compactly 
cemented by finely crystalline calcite, containing 
some opaque, granular impurities, probably of the 
nature of iron and copper pyrites. 
Crinoid remains.
