94 STUDIES ON AUSTRALIAN MOLLUSCA, 



with specimens kindly forwarded by the author. It had not 

 been previously noticed beyond the borders of South Australia. 



Amauropsis moerchi, Adams & Angas. 



(Plate iii., tig. 4.) 

 Adams & Angas, Proc. Zool. Soc. 1863, p. 423. 

 Only two examples of this rare species were taken by Angas; 

 he found them "adhering to the under surface of a large stone, 

 at Watson's Bay, just inside Port Jackson Heads, during an 

 unprecedently low tide" (P.Z.S. 1867, p. 198). Another was 

 collected by Brazier under a stone at Point Piper (Proc. Roy. Soc. 

 N.S.W. xxiii. 1889, p. 259). The fourth known specimen 

 occurred to me at Twemlow's Reef, Middle Harbour, under a 

 stone on muddy ground in the mangrove (Avicennia) zone, in 

 company with such mud-loving .species as Phenacolepas cinna- 

 momea, Gould, Pleeotrema bicolor, Pfr., and Columbella regulus, 

 Souverbie. 



Mr. Brazier is acquainted with the species by sight, having 

 derived his information direct from Angas. He has kindly con- 

 firmed my determination, indeed from literature alone no identi- 

 fication could be made. To assist future observers I now tender 

 a drawing of my specimen, which is 5 mm. in diameter. Angas 

 describes his as 5 lines in length. The youth of my example is 

 perhaps the reason why it fails to agree with the diagnosis by 

 being perforate. 



LODDERIA MINIMA, T. Woods. 



(Plate iii., figs. 1, 2 & 3.) 



T. Woods, Trans. Roy. Soc. Vic. xiv. 1877 [1878], p. 58; 

 Tate, Trans. Roy. Soc. S.A. xxiii. 1899, p. 222. 



This tiny shell has not been previously known from this coast. 

 I have been fortunate enough to detect several specimens in sand 

 in a rock pool at the base of the cliff on the east side of Middle 

 Head, Sydney Harbour. These were identified by comparison
