NOTES ON THE NOMENCLATURE OF SOME 

 LIFU SHELLS. 



By J. R. LE B. TOMLIN, M.A. 



(Read before the Society, March gth, 1910). 



Mangilia (Cythara) euselma M. & S. (/. of C, viii., p. 284). 



Mangilia eudeli Sow. (type in Brit. Mus.) described iny. of Maine, 

 viii., p. 102, is identical. The brown banding varies very much in 

 extent and character, sometimes becoming rather blotchy, sometimes 

 reduced to a few dots. 1'he name euselma has four years' priority. 



Mangilia (Glyphostoma) latirella M. & S. (I.e., p. 287). 



Examples of gaidei Herv., and its var. brachyspira Herv. in the 

 Brit. Mus., received ex and., make it clear that latirella and^a/a'^/ var. 

 braciiyspira are identical, and the latter name has priority. I may add 

 tliat Mr. Melvill very kindly had the type specimen of latirella down 

 at the Brit. Mus. for comparison. 



Clathurella episema M. & S. (I.e., p. 294). 



This name yields in priority to eiizonata Herv., which was described 

 in ihejourn. de Conc/i., vol. 44, no. 2. This number of the Jourii. de 

 Conch, bears date April 1896, but did not appear till October 1897 

 (cf. Melvill in /. of Conch., viii., p. 419), which gives the name 

 euzonata a priority of one month ! 



The identity of the two species is established by an author's example 

 of euzonata in the Brit. Mus. Mr. Melvill has very kindly verified the 

 dates for me. Mr. Edgar Smith entirely confirms the three identifi- 

 cations given above. 



Mangilia (Glyphostoma) notopyrrha M. & S. (I.e., p. 288). 



This very pretty and distinct little species has been recently distri- 

 buted under the name of albostrigatum Baird. An examination of 

 Baird's type, however, which is in the Brit. Mus., and was described 

 in 1873, shows that his species is the same as apiculatuin Montrou- 

 zier (1864) — a common New Caledonian species. Mr. Smith also 

 concurs in tliis identification. 



Pleurotoma (Drillia) regia Beck (/. of Conch., viii., p. 94). 



The rather common Lifu species catalogued under this name was 

 described and figured by Souverbie as P. roiigeyrotti {Journ. de Conch., 

 1874, p. 187). It is unquestional)ly close to regia Beck, but in the
