Obs. — A left valve, 30 x 40 mm. was forwarded to Mr. T. Iredale, 

 London, for comparison with types, and he Avrites : " Agrees 

 exactly with the types in the British Museum of Dosinia grata, Des- 

 hayes . . . from Tasmania, collected by R. Gunn. . . Tate and May 

 (p. 429), place D.(/rata, Deshayes, as a synonym of D.circinaria, 

 Deshayes, Avhich it is not, types compared." 



Much confusion has arisen respecting this species, and to Aus- 

 tralian conchologists its identification has been perplexing, owing 

 in the first place to Tate giving a wrongful figure, l and at the same 

 time quoting D.diana, Adams and Angas. as a synonym. In 1897 — 

 reference above given — he corrected this, stating : " The type of 

 D.diana, Adams and Angas, and the shell I figured as D. grata are 

 certainly the same, but they are different from D. grata. ^^ Tate and 

 May2 cited the species as a synonym of D.circinaria, Deshayes, from
