 It was reported from the Swan River, Western Australia. 



BlTTIUM TURRITELLIFORMIS [-e] AngaS. 



Angas, Proc. Zool. Soc. 1877, p.174, Pl.xxvi. f.14. 



I suggested to Mr. E. A. Smith that my Seila attenuata, 

 described in the first Part of these Studies, might be a synonym 

 of the above species of Angas, if his figure and description could 

 be construed with some latitude. Mr. Smith replied (i.vi.08) — 

 "Angas never gave us any specimens, so perhaps he lost the type, 

 being such a small object, or he may have returned it to Brazier. 

 I think, however, that your shells are this species. Angas 

 described the whorls as convex, so I regard the figure as 

 inaccurate." 



Since the type of Angas' species is lost, and his figure and 

 description are bad, there would be some justification for aban- 

 doning his species. I would, however, prefer to assume that he 

 dealt with a young attenuata and to withdraw my name in favour 

 of his. 



S. attenuata has been recognised in Victoria by Pritchard k 

 Gatliff.*
