ON SOME NEW TASMANIAN MARINE SHELLS. 



[Second Series.]

In the Proceedings of the Royal Society for last year 

 (1875), I published descriptions of 82 new marine shells 

 occurring in the Tasnianian seas. I have now to bring 

 under the notice of the Society an equal number which 

 have been derived from the following sources : — 1st. From 

 ]\Ir. Ronald Gunu, F.L.S., the eminent botanist, so long 

 connected with your Society, whose extensive collections, 

 extending over many years, were placed at my disposal for 

 description and type specimens of all presented to the 

 Museum. 2nd. From the collections made by Mr. W. F. 

 Petterd, during some years past, which were purchased by 

 a few gentlemen and presented to the Society, to which 

 also several new and rare species were added by the col- 

 lector. Mr. Petterd has proved himself to be an indus- 

 trious and most painstaking collector, who has not only 

 had singular advantages for observation in his extensive 

 travels, but has also been able to visit nearly all the Aus- 

 tralian museums in the course of his wanderings, and very 

 much enhance the value of his collections by comparison 

 with the types therein preserved. 3rd. From the Rev. 

 H. D. Atkinson, who has continued most successfully his 

 dredging operations and thus largely increased the know- 

 ledge of our fauna, as the following pages will show, 

 amongst which are several genera new to the Southern 

 hemisphere, including the important discovery of a Scis- 

 surella, differing but little from the European S. crispata. 

 4. From Mr. W. Lcgrand, who continues his zeal and 

 industry on behalf of conchological science, which already 

 owes much to him 5. From Mr, Augustus Simson, the 

 entomologist, whose duties unfortunately take him so far 

 from the coast that he cannot always render that valuable 

 assistance which his great industry and powers of observa- 

 tion would enable him to do. 6. From Mr. R. M. Johnston, 

 the geologist, of Launceston, who has presented two or 

 three interesting conchological novelties to the Museum, in 

 addition to his very large collection of fossils. 



The shells hereafter described comprise rare and peculiar 

 forms, but not departing in any remarkable degree from 

 the molluscan character of the Australian seas as far as at
