ON A COLLECTION OF LAND AND FRESH WATER 

 SHELLS, FROM QUEENSLAND 



By C. Hedley, F.L.S., and C. T. Musson, F.L.S. 



Through the kindness and liberality of Dr. J. C. Cox, F.L.S., 

 one of the writers, Mr. Musson, was enabled to spend a few 

 months during the year 1887 searching for mollusca in South 

 Queensland. The visit chanced to be when a prolonged drought, 

 followed by disastrous floods, had greatly reduced the invertebrate 

 population. Many species are thus only represented in Mr. 

 Musson's collection by dead shells. Others in the lapse of time 

 have been lost or mislaid, among them a slug discovered twice at 

 Miriam Vale, first under a log near the head station and then on 

 a ridge near Colosseum Creek, and again under Mt. Mee, North 

 Pine River. It is described in the collector's note-book as, " one 

 inch long, dark in colour, with sole of foot light except the rim 

 which was dark, sharply keeled, hard and leathery." We are 

 disposed to conjecture that this animal was Atopos australis, 

 Heyneman. 



The route pursued was as follows : — From Gladstone, reached 

 August 8th, as a centre various points in the Port Curtis district 

 were investigated, and Miriam Vale, Warro, Rodds Bay, Boyne, 

 Facing and Curtis Islands were visited in succession. Rockhamp- 

 ton was then made the base of operations, and part of September 

 and October was spent in collecting over the Berseker Range 

 (one of whose highest summits is Mt. Archer), Gracemere, Mt. 

 Morgan, and Olsen's Caves ; shells from a subfossil deposit in the 

 latter will be quoted as (c) in the following list. A trip west was 

 also made to Jericho, Alpha, and Bogantungan via Coomooboolaroo. 

 Leaving Rockhampton on October 12th, an overland journey to 

 Brisbane was commenced by way of West wood, Calliungal on the
