line of all but the last whorl occupied by small, semi-separate nodes ; carina of the last 
whorl without any apparent upward flexure, but below it is a second and finer sub- 
parallel keel, which diverges somewhat downwards ; general surface covered with 
revolving strife. 
Obs. The outer lip, with its digitation or digitations, is unknown, and the inner 
lip not preserved. Through the non-preservation of those portions and the canal, it is 
difficult to accurately determine the genus to which this shell should be referred. It 
may be either Aporrhais, Ancliura, or Drrpanochilvs ; but from the divergence of the 
revolving carinae on the last wffiori, and thereby probably indicating two digitations of 
the outer lip, one of the two former is the most likely. In their present condition our 
specimens are not unlike Dicroloma, Gabb. ; but the species may for the present be 
referred to Anchura provisionally. 
It is possible that the “ AJnria or Anchura" figured * by Mr. Iludleston from 
South Australia is a different species from A. ? WilMnsoni. The latter is named in 
honour of the late Mr. C. S. Wilkinson, Government Geologist of New South Wales.

Ohs. Small portions of the shaft of a pen (PI. 35, fig. 2l),w’ith the lateral 
expansion of the wings, indicate the presence of a Cephalopod allied to the Calamarios. 
The remains are all fragmentary. {Moore.)

^elemnites australis, Phillips in Moore, Quart. Journ. Geol. Soc., 1870, xxvi., p. 258, t. 16, f. 1 and 2. 
Sp. Char. Guard hastate, depressed in the postalveolar region by lateral expan- 
sion ; ventral face somewhat flattened, but without trace of a ventral groove ; two lateral 
grooves sharply cut,, and approximating to the ventral face in the alveolar region, thence 
bending toward the dorsal aspect, and continued in a fine stria on the middle of the side. 
Length four and a-half inches to the point where the guard grows, thin over the phrag- 
macone ; diameters at the alveolar apex 0 725 and O'GOO, further back in the more 
flattened part 0'770 and O'GOO. Axis of the guard 3'300. Proportion of axis to ventro- 
dorsal diameter as 550 to 100, of ventral to dorsal radius as 40 to GO. Phragmacoue 
unknown, its angle 20°. {Phillips.) 
Ohs. A much older specimen is a split half, the fissure being dorso-ventral. It 
shows the lateral groove, marked with a double stria, and the nearly straight-sided 
excentric alveolus. The axis of the guard is curved, and channelled, as in some specimens
