SOME NKW OR NOTKWORTHY SHKLLS IIKDLKY. 159 



Gabriel fortunately obtjiinetl the real Akera tasvuiiiica, illustrated 

 the shell and corrected my error. Their identification was 

 confirmed by Mr. W. L. INlay,'^"' who, with I'lof. 11. Tate had 

 redescribed it. From these gentlemen's observations it is clear 

 that I was misled by a wrong identification. This I now with- 

 draw and bring forward the Ili/datina as a new species distinct 

 from Beddome's Akera. 



Hah. — The original of the present figure and description (type) 

 I obtained (15 5/02) from a bottle sunk in a rock pool at Middle 

 Head, Sydney. Miss Lodder's shell which I drew and returned 

 probably came from North Tasmania, perhaps Ulverstone. 



Philine angasi, Crosse and Fischer. 

 (Plate xliv., figs. 42, 43). 



A large Philine, common on the Australian and New Zealand 

 coasts was described by Crosse and Fischer as Bnlhea angasi, 

 and they afterwards remarked that it was abundant at Suez.^® 



This Suez form w.as subsequently named P. vaillanti by Issel. ^ ^ 



The Australian form has usually, but not unanimously, been 

 maintained as distinct. Kobelt indicates"^ as supporters, Angas, 

 Brazier, Sowerby, Hutton, Watson and Pilsbry. The first to 

 question the current nomenclature was Tenison Woods®® who 

 referred the Tasmanian mollusc to P. aperta, Linn.; in this he 

 was followed by Tate and May. '^'* To the European P. aperta, 

 Cook has united both P. angasi, P. vaillanti, Issel, and P. 

 erythrcea, H. Adams. ^^ Treating of the New Zealand form 

 Suter'^^ reduces P. angasi to a synonym of P. aperta. On the 

 contrary when discussing the Victorian mollusca, Pritchard and 

 Gatliff"' distinguish P. angasi from P. ajjerta.
