PURTHKR ADDITIONS TO THE TASMANIAN 



MOLLUSCA. 



By VV. L. May. 



(Read June 10th, 1912.) 



PI. II. 



In this paper I have added eighteen species to our 

 list, which have been described by various authors from 

 Australian or New Zealand sources. The occurrence of 

 three more New Zealand species is interesting ; but especi- 

 ally so is that of a large form of Pecten, taken living in 

 100 fathoms off Cape Pillar, and which was described from 

 fossil material by the late Professor Tate. 



I also describe eight species, which appear to be new 

 to science, and are the results of various dredging excur- 

 sions. They do not present any great novelty to our 

 previously known fauna. I have drawn the illustrations 

 under the camei'a lucida from the type specimens, which 

 will be presented to the Tasmanian Museum. 



PYRENE AXIAERATA, Verco. 



T.R. Soc, S. Aust., Vol. XXXIV., 1910, p. 129. 



100 fathoms, off Cape Pillar, 3 ; 80 fath., off Schouten 

 Id., 1 ; 50 fath., off Maria Id., 1 All dead. Our ex- 

 amples are white, with several apical whorls, rose colour, 

 which is a good specific distinction. 



MATHILDA DECORATA, Hedlev.

One specimen from 50 fathoms, off Maria Island, 

 which, although larger than the type, seems otherwise 

 indistinguishable.
