Lamarck's Arrangement of the Testacea, in 1824. Wood, in 

 his Index Test. Supplement, 1828, figures it as JBuccinum semi- 

 granosum from specimens in the British Museum. Kiener, in 

 his Coquilles Vivantes, figures it as Cassis semigranosa, Lam. 

 Deshayes, Catlow and Eeeve, Jay, H. and A. Adams, Hanley, 

 Chenu, Theobald, Angas, Paetel, Tenison-Woods, all quote 

 Lamarck ; and after 62 years we are told that Wood is the 

 authority for the species by Mr. Tryon, in his Manual of 

 Conchology, vol. 8, p. 275, 1885, and quotes Reeve, Conch. 

 Icon., for it. Eeeve does not quote Wood, but Lamarck, 

 Anim. sans Vert. (Deshayes' edit.), vol. X., p. 37. Kiister, in 

 •Conchilien-Cabinet, Martini and Chemnitz, 2nd edition, 1857, 

 quotes Wood, and ignores Lamarck. Of all the authorities I 

 have quoted from 1822 until 1885, Kiister and Tryon are the 

 only two who have given Wood as the authority — probably an 

 •oversight ; but it causes endless confusion to young students 

 who have not a large library to consult. I am very often asked 

 who is the authority for the species, Lamarck or Wood. My 

 list drawn up in this paper will show all students the authority 

 for the species.

 Sab. — Van Diemen's Land ( Sowerby) ; Torke's Peninsula, 

 Adelaide Creek, South Australia (G. F. Angas); on the beach 

 at St. Kilda, Melbourne (G. F. Angas) ; occasionally taken 

 alive in shallow water in St. Vincent G-ulf, and beach speci- 

 mens have been gathered at several stations in Spencer Gulf 

 {Tate). 



Sowerby described in his Mineral Conchology, in IS 16, a 

 'Cerithium dubium. Bayle, in the French Journal, 1880, re- 

 names it as Cerithium eludens, not knowing that Crosse and 

 Fischer had described it as Cerithium monachus in the same 

 Journal for 1864. Crosse and Fischer's name must stand 

 good.
