1896. Ischnochiton (Ischnoradsia) australis, Sykes. P. 



Malac. Soc. Lond., vol. ii., No. 2, pp. 89, 90. 



Hab. — Oommon along the coast generally. 



Obs. — Mr. Sykes confirms Mr. Pilsbry's inclusion of C. 

 metallicus. Reeve, in the synonymy of the above on an exami- 

 nation of the types. Mr. Pilsbry also includes C. evanidus,. 

 Sowerby, as a synonym, but with regard to this we are not in a 

 position to speak.
