ADDITIONS AND EMENDATIONS. 1083 



Drupa Bollonsi, Suter. 1906. 



Iredale (P. Mai. S., ix, 75) gives it as his opinion that the shell 

 described by me as new is the same as that figured in Mem. A.M., ii, 

 1889, pi. 4, f. 1-4, 7-12, 21, 22 (the figures are reversed), and named, 

 but not described, by Brazier as Purpura (Polytropa) Smithi, from Lord 

 Howe Island. I accept his view, and Brazier's name has priority. 

 Iredale does not consider it a Drupa. For the present I see no reason 

 why it should not be retained in that genus. 



Gadinia nivea, Hutton, 1878. 



Comparing typical New Zealand specimens with types of G. 

 conica, Angas, and its synonyms, Iredale has come to the conclusion 

 that our species is conspecific with G. conica, Angas. Hutton already 

 stated in his M.N.Z.M., 202, that G. nivea may be the same as G. 

 conica, Angas, for specimens received from Mr. Brazier show that it 

 is not always so conical as represented by Mr. Angas. 



Iredale (I.e., 78) gives the following synonymy : Gadinia conica, 

 Angas, P.Z.S., 1867, 115, 220, pi. 13, f. 27. G. pentegoniostoma, 

 Sowerby : Angas, P.Z.S., 1867, 220. G. conica, Angas : Dall, Arner. 

 Journ. Conch., 1871, vi. 11. G. Angasii, Dall, I.e. Siphonaria albida. 

 Angas, P.Z.S., 1878, 314, 869. pi. 18. f. 14, 15. Gadinia nivea, 

 Hutton, J. de Conch., xxvi, 1878, 36 ; M.N.Z.M., 37, 202 : T.N.Z.I., 

 xv, 1882 (1883), 144, f. S-V. 



Hob. Australia ; New Zealand ; Kermadec Islands. 



Philobrya costata, Bernard, 1896. 



Iredale (I.e., 79) declares that Philobrya Filholi, Bernard, is the 

 young of P. costata. The measurements given by Bernard for P. 

 Filholi are evidently wrong, and they should read as follows : Diam. 

 autero -posterior, 1-9 mm. ; dorso-ventral, 2-0 mm. I consider the 

 two species to be quite distinct. 



Soletellina biradiata, Wood, 1815. Plate 62, fig. 13. 



Solen biradiata, Wood, General Conch., 1815, 135, pi. 33, f. 1 ; Index Test., 

 1825, 15, No. 26, pi. 3, f. 26. Soletellina biradiata, Wood : Reeve, 

 Conch. Icon., x, 1857, pi. 2, f. 7 ; Tate, T.R.S. S.Aust., ix, 87. Hiatulu 

 biradiata, Wood : Tryon, Am. Journ. Conch., iv, Suppl., 78. Psam- 

 mobia ftavicans, Lamarck, A.s.V., v, 1818, 514 ; Delessert, Recueil, v, 

 1841, f. 5 ; Menke, Moll. Nov. Holl., 184?, 41 ; Hanley, Cat. Rec. Shells, 

 1843, 57, pi. 11, f. 54; Philippi, Abbild. und Beschreib., i, 1845, 194, 

 pi. 2, f. 4, 6. Hiatula ftavicans, Lamk. : Bertin, Nouv. Arch. Mus., iii. 

 1880, 88. Solen lividus, Wood, Index Test., Suppl., 1828, 3, pi. 1, f. 3. 

 Soletellina nymphalis, Reeve, Conch. Icon., x, 1857, pi. 1, f. 2. S. epi- 

 dermia, Reeve, i.e., pi. 1, f. 3. 8. Hedleyi, Sowerby, P. Mai. S., vii, 1907, 

 302, pi. 25, f. 12.
