 abled to enter in consequence of the perfect state of preservation 

 of the animal in the Society's collection, and which he signified 

 his intention of speedily submitting to the public, were of con- 

 siderable importance and interest.

November 4» — A paper was read entitled, '' An Account of 

 some Geological Specimens collected by Captain P. P. King, in 

 his Survey of the Coasts of Australia; and by Robert Brown, 

 Esq., on the Shores of the Gulf of Carpentaria, during the Voyage 

 of Captain Flinders; by W. H. Fitton, M.D. V.P.G.S., &c. The 

 only part of this paper which requires notice in the Zoological 

 Journal, is an account of a recent breccia containing shells, of 

 which the following is an abstract : 



The shore on the western coast of Australia is in several places 

 covered with extensive dunes of sand, with which are associated 

 in many instances beds and masses of a very recent arenaceous 

 breccia, abounding in shells concreted by carbonate of lime. This 

 formation, which is particularly remarkable in the islands and on 

 the shores adjacent to Shark's Bay, about latitude 25°, is analogous 

 to that which occurs very extensively in Sicily, at Nice, and 

 several other places on the shores of the Mediterranean, and of 

 the West Indian Islands, and on many parts of the coasts within 

 the Tropics. In New Holland it generally consists of sand, ce- 

 mented by stalagmitic or tufaceous carbonate of lime, containing 

 angular fragments of a compound of the same nature, but pre- 

 viously consolidated and broken, along with numerous shells and 

 fragments of shells, very nearly resembling those of the. adjacent 

 seas. Its date appears to be more recent than that of the beds
