Perry, in June, 1810, independently provided : Triplex ; type, T. 

 foliatus : in December, 1810, Aranea ; type, A. gracilis-: and in 1811 

 Hexaplex ; type, H. foliacea : the last-named being noted in June, 1810, 

 as a nomen nudum only. 



Of the above names, Bronte* and Aranea cannot be legitimately used, as 

 both aie preoccupied. 



Swainson, as above recorded, seems to have been the next, recognizing 

 five subgenera, ignoring previous workers, and therefore introducing five 

 new names, thus : Murex Auct., Haustellaria, Centronotus, Phyllonotus, and 

 Pteronotus. The fifth, Pteronotus, seems to have not been previously in- 

 dicated, and is a valid group. In 1840 Swainson added as distinct genera 

 Muricidea and Vitulina. These are proposed in the Treat. Mai., p. 64, 

 where the types are named as of the latter, the Murex vitulinus of authors 

 and of Muricidea p. 65 Murex magellanicus. On p. 296 Muricidea has 

 seven species noted, whilst on p. 297 Vitularia is written. I note this as 

 the latter spelling is commonly used for a distinct group, whilst Muricidea 

 was used for a subgenus of Murex by H. and A. Adams, though the type- 

 designation of Swainson himself makes it an absolute svnonym of Trophon 

 Montfort, 1810. 



The four outstanding genera would seem to bear the following names :— 



Murex Linne, Syst. Nat., ed. x, p. 746, 1758. Type : Murex tribulus 



Linne. 

 Chicoreus Montfort, Conch. Syst., vol. ii, pp. 610-11, 1810. Tvpe: Murex 



ramosus Linne. 

 Pteronotus Swainson, Zool. Ulustr., 2nd sex., vol. iii, 1832-33, pi. 122. 



Type : Murex pinnatus Swainson. 

 Hexaplex Perry, Conchology, pi. viii. 1811. Tvpe : H. foliacea, fig. 4 



= cichoreus Gmel. 



As early synonyms of Murex Linne, may be noted Aranea Perry, 1810, 

 preoccupied ; Brontes Montfort, 1810, preoccupied ; Haustellaria Swainson, 

 1833 ; and Haustellum H. and A. Adams (ex Klein) ; and probably many 

 more. 



I do not see any more than subgeneric difference in the group typified 

 by Murex haustellum Linne, though this was separated generically by Mont- 

 fort in 1810, and has been given equal rank ever since with the divisions 

 I call genera as above. 



Jousseaume, in the Rev. Mag. Zool., 3rd ser.. vol. vii. 1879, p. 314 et seq., 

 divided the Purpuridae (= Muricidae) into very many genera. I give 

 the names here, as they have not been recorded in Waterhouse's " Index 

 Zoologicus " until given in No. ii, where they are given as appearing in 

 " Les Naturalistes." 1883. Jousseaume's names read as follows : — 



P. 32 : Purpura Tournefort. Type : brandaris L. 



Haustellum Klein. Type : haustellum L. 

 P. 323 : Tubicauda nov. Type : brevispina L. 

 P. 324 : Acupurpura nov. (ex Bayle MS.). Type : tenuispina Lam. 



Siratus nov. Type : sir at Adamson. 

 P. 325 : Paziella nov. Type : pazi Crosse. 



Poirieria nov. Type : zelandicus Q. & G. 



Biplex Perry. Type : perca Perry. 

 P. 326 : Naquetia nov. Type : triqueter Born. 



Inermicosta nov. Type : fasciata Sow. 



Muricanthus Swains. Type : radix Gmel.
