latter as a new species. For critical remarks on Cingulina 

 brazieri, the reader is referred to an appendix to this paper, 

 kindly contributed by Mr. E. A. Smith {postea, p. 211). 



Strombus urceus, Linn. 



Stromhus urceus, Linn., Syst. Nat. x. 1758, p. 745. 



It has been pointed out by Hanley* that this Linnean name 

 has been always misapplied. He stated that Linne's type (well 

 represented by Thes. Conch, i. pi. vii., f. 45) is identical with 

 Stromhus Jloridus, Lamarck. But the species commonly known 

 as S. urceus, Linn., is rightl}^ S. ustulatus, Schumacher. 



This information is not new; but as ever}^ writer on Austra- 

 lian Mollusca, from Angas in 1867 to Pritchard and Gatliff in 

 1 900, has gone astray in the matter, it seems well to here restate 

 the facts. 



ACMiEA OCTORADIATA, Hutton, 



Patella octoradiata, Hutt., Cat. Marine Moll. N.Z. 1873, p. 44. 



AcincBa saccharlna, Linn., var. perplexa, Pilsbry, Man. Conch, 

 xiii. 1891, p. 50, pi. xxxvi., figs. 69, 70, 71. 



Pilsbry cites Hutton's name with doubt as belonging to his 

 variety. Following this suggestion, I sent a series of this shell from 

 Maroubra Bay to Prof. Hutton, who kindly replied (2 : iv. : '04), 

 " The Acmcea is truly my Patella octoradiata. I withdrew it 

 from my second edition because I doubted the correctness of the 

 locality. But since then it has been again found in New 

 Zealand." 



I agree with Taylorf and with Pritchard & Gatliff :|: in regard- 

 ing the form under notice as a valid species. In reviving 

 Hutton's prior name, another species is added to those common 

 to Australia and New Zealand. 



Since writing this note, I have received from Captain Hutton 

 his ' Index Faunae Novse Zealandiae,' in which (p. 85) the above 

 synonymy is for the first time recognised.
