616 STUDIES ON AUSTRALIAN MOLLUSCA, 



ally a form of T. granifera^ under the name of T. fasciata. Thus 

 Brazier was misled into identifying (these Proceedings (2) ix., 

 1894, p. 694) T. scitulus as from Sydney and as identical with 

 T.Jasciata. Tate tfe May have remarked that the two species 

 cannot be the same (these Proceedings, 1901, p. 457). 



To digress an instant, I would hazard the conjecture that 

 Triphoris scihdus, A. Ad., (Proc. Zool. Soc. 1851, p. 278) from 

 Port Lincoln, S.A., is probably identical with T. pfeifferi, Crosse 

 and Fischer (Journ. de Conch. 1865, p. 47, pi. i., ff. 14, 15). It is 

 significant that T. 2?feifferi but not T. scitulus appeared in the 

 first South Australian list published by Angas, though he included 

 the latter in his supplement (Proc. Zool. Soc. 1878, p. ©67). 



By its ornament T. fasciata recalls T. pfeifferi, Crosse and 

 Fischer, a longer, narrower shell in which the inequality of the 

 gemmule rows is further exaggerated. Indeed Tasmanian col- 

 lectors have sent me T. fasciata labelled T. pfeifferi; and accord- 

 ing to Woods' own shell in the Tasmanian Museum (kindly lent 

 to me for the purpose of this article by Mr. A. Morton) T. pfeifferi 

 itself was distinguished by Tenison- Woods as "7". tasmanica var. 



It is only through the great kindness of the Rev. H. D. 

 Atkinson, who has lent to me part of the original series studied 

 by Tenison Woods, that I am now enabled to recognise and 

 rehabilitate the species. This authentic material shows that the 

 original diagnosis was obscure and confusing. I therefore add 

 here the figure and description I had prepared from material col- 

 lected in Sydney Harbour by the late Mrs. Starkey and by H. L. 

 Kesteven, an account I composed under the impression that I was 

 dealing with a new species. 



Shell small, narrow, translucent, glossy. Colour white, base 

 and supersutural thread orange-brown. Whorls ten, plus a pro- 

 toconch of five and one-half whorls. Sculpture : base smooth, a 

 plain supersutural thread, followed by two rows of gemmules, the
