8p. Char. Shell transversely oblong or semicircular, wider than long, both 
valves ornamented with many ribs ; hinge-line straight, not so long as the width of the 
shell ; area narrow and parallel ; ventral margin convex. Cardinal angles rounded and 
flattened at their extremities. Ventral valve slightly convex. Dorsal valve nearly flat, 
or following the curve of the ventral. Beak small, apparently slightly incurved, but 
not covering the hinge-line. The place of the hinge-spines faintly traceable. The 
surface of the shell covered by what must have been short and stout spines numerously 
distributed. {Etheridge.) 
Ohs. Mr. Etheridge considered that his species differed from the typical f* 
Carboniferous Chonetes hardrensis ( = C. laguessiana), De Koninck, by possessing ' f 
flatter cardinal angles, and many more spines. On the other hand, Prof. De Koninck 
united G. cracoioensis with his G. laguessiana, and guided by his universally accepted 
high opinion, I followed a similar course in the “ Catalogue of Australian Fossils.” j. 
But an examination of numerous specimens from the Star Eiver Beds causes me to i 
doubt the advisability of this course, especially when Mr. Etheridge’s figure, which | 
excellently represents his species, is compared with that given by Prof. De Koninck of J 
the shell from Kew South Wales. The figure of G. cracoioensis represents a form with 
flat roundly rectangular sides, whereas the so-called G. laguessiana figured by De 
Koninck has acute cardinal angles, and the lateral margins rapidly and sharply merging 
into the ventral margins. I quite fail to see how two such differently shaped shells can 
be relegated to one species, and it will be better, in the meantime, to accept the name J 
applied by Mr. Etheridge to this shell. >

Ohs. A transversely semicircular, deep, and very convex, or, in fact, almost 
deltoid species, occurs in the Corner Creek Beds. It possesses the general form of 
Chonetes polita, McCoy,t but, unlike the latter, is strongly costate. The alar angle® I 
are pointed, and it is altogether an elegant little shell. 
* In this, as in the caaeof Protinctos brachythcerus, I doubt the correctness of the locality quoted, a® 
the Darr River is wholly in the Rolling Downs Beds. (B.L.J.)
