ADDITIONS TO THE CATALOGUE OF THE 

 MARINE SHELLS OF TASMANIA. 



By W. L. May. 



(Read August 8th, 1910.) 



In the Proceedings of this Society for 1908 I pub- 

 lished a hst of additional species, and since that date a 

 considerable number of ncAv forms have come under my 

 notice, which it is the object of this paper to place on 

 record. 



The greater number of the following species were 

 obtained during the Easter camp-out of the Tasmanian 

 Field Naturalists' Club at Freycinet Peninsula, in March, 

 1910. 



The s.s. Koonookarra, Captain R. Holyman, had been 

 chartered by the Club, and was available for dredging, 

 much of the success of the operations being due to the 

 ability and active interest of the genial skipper. I had. 

 provided suitable dredges and 200 fathoms of wire rope, 

 and on the two days (March 26 and 27), assisted by several 

 interested friends, I dredged in Geography Strait and due 

 east from there in 15, 40, 60, and 80 fathoms, the greatest 

 depth being some ten miles off the coast. The nature of 

 the bottom was very similar to that ofif Cape Pillar, ex- 

 plored by Mr. C. Hedley and myself in 1907, but not quite 

 so hard, and there is probably considerably less current. 

 Broken up polyzoa was very abundant. As was to be 

 expected, many of the same species occurred which were 

 taken off Cape Pillar in 100 fathoms; but, partly owing 

 to shallower water being explored, and to tlie station 

 being some sixty miles further north, many new species 

 were taken, and also several most southern records of 

 known Tasmanian shells, previously only known from 

 Bass Strait.
