Genus Phasianella (Lamarck, 1804). [P. 168.] 



Many synonyms might here be added. The following refer only to the 

 typical section, and are absolutely exact : — 



Phasianus Montf ort, Conch. Syst., vol. ii, pp. 254-55, 1810 (not Phasianus 

 Linne, 1758). 



Bolina Rafinesque, " Analyse Nature," p. 144, 1815. Orthopnoea Gistel, 

 Naturg. Thierr. Schul., p. 169, 1848. Both these are simply substitute 

 names for " Phasianella Lam." 



Eutropia Humphrey was quoted by Swainson (Treat. Mai., p. 21, 1840) 

 as being equal to Phasianella Lam., and was so used by Adams Bros. 



Eutropia H. and A. Adams, Gen. Rec. Moll, vol. i, p. 389, 1854. 



Genus Umbonium (Link, 1807). [P. 170.] 



Umbonium Link, Beschr. Samml. Rostock., 1807. Type : Trochus 

 vestiafius Linne. 



As synonyms may be noted Globulus Schumacher, 1817, and Rotella 

 Lamarck, 1822. A full synonymy will be given later. 



This genus is not clearly defined from Etkalia A. Adams, which Suter 

 has used, following Pilsbry, for the New Zealand shell l " Ethalia zelandica 

 H. & J." In the British Museum Ethalia is only given subgeneric rank, 

 which looks natural to me ; but whatever value is hereafter accorded Ethalia 

 I conclude that the Neozelanic shell will be classed in Umbonium. It is 

 so placed in the British Museum. Ethalia is much younger, in date, than 

 Umbonium, but even if used subgenerically the Neozelanic shell would fall 

 into Umbonium s. str. Ethalia must be altogether eliminated from Neo- 

 zelanic usage. 



Umbonium anguliferum (Philippi, 1853). [P. 170.] 



Globulus anguliferus Philippi, given by Suter in the synonymy of 

 "" Ethalia zelandica Hombron and Jacquinot, 1854," was really published 

 in 1853, and therefore lias clear priority over the name assigned to Hombron 

 and Jacquinot, but only published by Rousseau in 1854. 



The reference to the genus Ethalia is due to Pilsbry's initiative when 

 he monographed the group in the '" Manual of Conchology." I cannot 

 understand his argument, as he referred Crosse's U. thomasi to Umbonium, 

 and these two species are very nearly allied, and certainly congeneric. 

 I note he has since indicated that the traditional identification of Quoy 

 and Gaimard's guamensis, the type of Ethalia. may be incorrect. How- 

 ever, A. Adams (Proc. Zool. Sue. 1853. 188 (1854) ) proposed two new species 

 of Umbonium — U . zealandicum and U. chalconotum. These are synonyms of 

 the present species, and they are not congeneric with H. and A. Adams's 

 Ethalia guamensis, which is now before me, whether this be Quoy and 

 Gaimard's species or not. The first introduction of Ethalia is by H. and A. 

 Adams, Gen. Rec. Moll., vol. i, p. 409, May 1854. The type is " guameuse 

 Quoy k Gaim." 



Genus Murdochia (Ancey, 1901). [P. 177.] 



1 would like to see this name come into use for the Neozelanic shells 

 at present classed in Lagochilus. All Neozelanic workers, as well as extra- 

 liniital malacologists, deeply regret the withdrawal of Mr. R. Murdoch from 

 the. active study of the Neozelanic molluscan fauna.
