16 Mr. R. Etheridge on some Specie.i of 



Strzelecki's work on New South Wales *, as Terebratula 

 compta. The Rev. Julian E. Woods has frequently alluded 

 to the occurrence of this little shell in the Tertiary deposits of 

 Southern Australia, in various papers communicated to the 

 Geological Society of London t and the Royal Society of 

 Victoria:}:, and again in his work on the geology of South 

 Australia, where it is also figured §. Mr. C. S. Wilkinson 

 informs us that T. compta occurs in the upper part of the 

 Spring-Creek section, about fourteen miles south of Geelong {|, 

 in beds which were regarded by Mr. R. Daintree as probably 

 the equivalent of the Mount-Gambier series^. In 1862 Mr. 

 Davidson described **, under the name of Waldheimia Gari- 

 haldiana, a species supposed to be from the Tertiary beds of 

 Malta, but which he now believes to be from South Australia. 

 Prof. M'Coy has named two new species of Brachiopoda from 

 Victorian Tertiary beds, viz. Terebratula corioensi's and Wald- 

 heimia macropora (but, so far as I am aware, he has not j&t 

 described or figured them), and has recorded the occurrence of 

 Rhynckonella lucida, Gouldff.

SjJ. char. Shell small, oval, flattened, tapering towards the 

 beak, rounded towards the front ; lateral margins in one plane, 

 not sinuous. Ventral valve slightly convex, with the beak 

 but little produced, truncated by a slightly oblique foramen 

 more or less below the apex of the beak, excavated out of its 

 substance, and completed by the two small deltidial plates and 

 the umbo of the dorsal valve. Imperforate or dorsal valve 

 almost flat, with the slightest indication of a mesial sinus in 

 the front ; hinge-line a little arched. Surface of both valves 

 ornamented with a large number of fine radiating ribs, occa- 

 sionally bifurcating, and a few concentric lines of growth ;
