oUvaceri, Dunker, the varieties of which are very numerous in 

 Port Jackson and on the coast in the Hving state. A number of 

 the Tasmanian species have been described from beach worn and 

 faded specimens. 



8. RissoiA (Amphithalamus), Petterdi, Brazier. 



1884. Rissoa pukheUa, Petterd, Journ. Conch. Yol. iv. No. 5, p. 

 138, Species 14 (non Rusoa 'pulclidla, Risso, nee pidchella, 

 Phihppi, nee pu.lchella, Danilo and Sandri). 



1887. Rissoia pulr.hdla, Tryon, Man. Conch. Vol. ix. p. 368. 



Hah. — North Coast of Tasmania and Isles in Bass's Straits (W. 

 F. Petterd); Cook's landing place, south side of Botany Bay, 

 under stones and in shell sand among the rocks (J. Brazier, 

 1864). 



A very pretty little species; when in good condition of a fine 

 bright brown, when sea worn of a dirty pale colour. 



The specific name pulchella is preoccupied by Philippi in 1836, 

 by Risso in 1826 for Rissoia atiriscaJpium, Linne, and by Danilo 

 and Sandri for Rissoia dccorata, Philippi, 1846; I take great 

 pleasure in renaming it after my friend, correspondent, and fellow 

 voyager, Mr. William Frederick Petterd of Tasmania.
