Synonymy of and remarks upon two Australian species of 



Melania. 

 By J. Brazier, C.M.Z.S., &c. 



1. Melania Tatei, Brazier. 

 Melania tetrica, Conrad (non Gould ) Proc. Acad. Nat. Sciences, 

 Phil., p. 11, 1850. American Journal Conch, ii., p. 80, pi. 

 1, fig. 9, 1866. Melania Balonnensis, Brot (non Conrad) in 

 Martini and Chemnitz, Conch. Cab. p. 287, pi. 28, fig. 14 

 and 14 b., 1874.

 Bay, Port Curtis and the upper Brisbane River, Queensland 

 (Brazier). Rivers of South-east Australia fConradJ. 



This species is only found in the rivers and small creeks of 

 New South Wales and Queensland. Mr. Conrad is evidently 

 wrong when he quotes the rivsrs of South-east Australia or his 

 specific names of M. tetrica and Balonnensis have got transferred. 



Dr. A. Brott in his " Materiaux pour servir a 1' etude de la 

 famille cles Melaniens. Additions et Corrections au Catalogue 

 Systematique des Especes qui composent la Famille des Melaniens 

 64 pages 3 coloured plates Geneva, 1868," considers M. tetrica and 

 Balonnensis of Conrad to be only local varieties of one species ; 

 but they are quite distinct. The Melania tetrica, Gould, 1847, is 

 a synonym of Melania bellicosa, Hinds, 1844. 



A new name being required for our Australian species I take 

 great pleasure of naming it after Professor Ralph Tate of South 

 Australia.
