Shale.—Jordan River, 2J miles above Jericho. Nos. 341 0, 341A 
Coll, by Mr. 0 . A. L. Whitelaw. 
Two impressions of a brachiopod, which may be tentatively referred to 
Siphonotreta. The shell, although incomplete, shows concentric growth 
lines, and traces of the tubular spines crossing the lamellae. The chitinous 
appearance of the original shell is well preserved. (One specimen re¬ 
tained for description.) 
Shale.—Little Jordan Creek, 50 chains above Jordan Junction. No. 
Coll, by Mr. 0 . A. L. Whitelaw. 
Lituites sp. A small form, probably new, allied to Z. lituus, Mont- 
fort. (Retained for description.) 
The specimens from both the above localities are of Ordovician age. 
Pyritous Mudstone, Coy’s Diggings, S. of Rushworth. Nos. 605-611. 
Coll, by Mr. S. B. Hunter. 
Dendroid markings resembling the so-called fucoid Bythotrephis . 
Probably of organic origin, and may be ascribed to a borer, as the 
branched markings are disposed at various, but low, angles to the bedding 
plane of the rock. They are compressed-elliptical in cross section. Simi¬ 
lar remains are found in both Ordovician and Silurian rocks.

Fossiliferous Limestone. Stony Creek, Limestone Creek, Benambra 
—Nos. 272-278. Coll, by Mr. E. J. Dunn, F.G.S. 
272. —This limestone specimen is of a pink tint, relieved with green 
veins. The rock is of organic origin, but is now almost entirely re¬ 
crystallized. The seams and veins of a greenish colour are due to 
chloritic and sandy impurities disseminated in reticulating stripes through¬ 
out the rock (see PI. XXIX., Fig. 1). The original limestone reef appears 
to have been broken up by local earth movements, and the intercalated 
layers of (?)volcanic gritty ash have surrounded and coated the 
brecciated fragments of limestone. A large amount of shearing has 
taken place during the dynamical movements of this limestone massif. 
The only organic remains decipherable in the limestone are—A fragment 
of a large stromatoporoid, crinoid ossicles, and valves of ostracoda, with, 
possibly, fragments of trilobite tests. 
273. —A gritty limestone, sheared and recrystallized. Organic re¬ 
mains chiefly crinoidal. 
274. —Limestone with corals ( Cyathophyllum ( ?)sweeti , Eth. fil. ; see 
Appendix and PI. XXIX., Fig. 2), polyzoa and crinoid ossicles. 
275. —Limestone with crinoid remains, shell fragments and corals, 
Cyathophyllum (?) sweeti , Eth. fil. (See Appendix and PI. XXIX., Fig. 
3). In this rock a fragment of a decomposed igneous (?) basic rock 
occurs.
