subject, and further he has crammed his paper with observations 

 and notes of such value, that it must constitute the principal source of 

 reference to future workers. The paper is well illustrated and it is 

 highly creditable to the Association that they have devoted so much 

 space to this, and so assisted the reader and rendered the work of 

 greater service. A list of the Pleistocene (non-marine) Mollusca is 

 a})pended, with the correct nomenclature, but such great confusion 

 still exists in the question of priority, that no doubt two of the 

 genera will be changed in the addenda to the completed volume. 



A full report of the Excursion of the Association to the Italian 

 Volcanoes, by Dr. Johnston Lavis follows, and should be of material 

 service to those who could not avail themselves of Dr. Lavis' per- 

 sonal guidance, on that interesting occasion. 



Professor Boulger contributes a paper on Copulus, containing 

 the description of a new species, illustrated by a coloured plate. 

 Other papers of great interest by Dr. Wheelton Hind, Major-Gen. 

 McMahon, T. P. Moody, H. W. Monckton, G. F. Monckton (Gold 

 Deposits of Nova Scotia), H. M, Klaassen, and W. J. Lewis Abbott, 

 complete this bulky number, but space does not permit us to notice 

 all these contributions in detail. 



V. — Eegords of the Geological Survey of New South Wales. 

 Yol. II. Part 1, pp. 1-36, with 3 tables, 2 plates and a map. 

 (Sydney, Department of Mines, 1890.) 



I. Mr. T. W. Bdgewokth David publishes a proposed " Petro- 

 logical Classification for the Eocks of New South Wales," giving the 

 terms, lettering and signs to be employed by the Survey. 



II. Under the name T. Lonsdalei. Mr. E. Etheridge, jun., 

 describes a new species of Tryplasma, Lonsdale (^PJiolidophyllum, 

 Lindstrom), from the Upper Silurian of N.S. Wales. The "pores " 

 described by Lonsdale, the existence of which was doubted by 

 Lindstrom, are explained as impressions of the thorn-like septa in the 

 matrix filling the inter-tabular spaces. In the same paper Mr. 

 Etheridge assigns doubtfully to DlphyphyJlnm a new species, D. 

 Porteri, from the Devonian limestones near Tamworth, N.S.W. The 

 specimens show interesting structural features, and suggest the 

 existence of an inner wall. 



III. Mr. W. Anderson has some notes of considerable practical 

 value " on the Tertiary Deep Lead at Tumbarumba," an auriferous 

 river-bed covered by lava-flows. The paper is accompanied by a map. 



IV. In a paper of anthropological rather than of geological interest 

 Mr. E. Etheridge, jun., describes and figures " The Aboriginal 

 Eock-Carvings at the Head of Bantry Bay, Middle Harbour, Port 

 Jackson," which he thinks " formed a portion of a Bora-ground, the 

 spot set apart for the performance of the initiatory mysteries attending 

 the entrance of youths into manhood's estate." 



V. is a note on Bromornis Australis, Owen, by the same writer. 

 Possibly the low price of this publication — Is. 6d. — is held to 



excuse the misprints that disfigure it : the Government printer should 

 have his attention drawn to these, especially in Article IL
