 1907. Acmaea alticostata, Verco. T.R.S. S.A., vol. xxx., 

 p. 209. 

 Hab. — Coast generally. 



Obs. — We cannot agree with Mr. Hedley and Dr. Yerco in 

 regarding A. alticostata as a distinct species, because Mr. G. B. 

 Sowerby informed one of us that he considered that it was con- 

 specific with A. costata, Sowerby, and Mr. E. A. Smith, of the 

 British Museum (where the type of ^1. alticostata is), said the 

 same thing. 



Acmaea latij^trigata, Angas. 



1903. Acmaea gealei, Pritchard and Gatliff (non Angas). 



P.R.S. Vic, vol. XV., n.s., p. 197. 

 1907. Acmaea marmorata, Verco. T.RIS. S.A., vol. 

 XXX., p. 210. 

 Hab. — Coast generally. 



Obs. — The former identification was made from a specimen 

 Bamed incorrectly A. f/ealei, received from South Australia. An 

 examination of the type of the latter in the British Museum 

 proved it to be a distinct form. It is much worn, and most 

 probably is conspecific with A. flaminca, Quoy and Gaimard.
