latter the granules are much finer and less prominent, the aperture 

 is somewhat more elongate, and the colour is pink and not red. On 

 the whole I should consider the two distinct. P. regia was described 

 from Amboina. In the same volume of the J. of C, p. 397, the 

 authors of the Lifu List also catalogue ''^ Drillia rougeyroni Souv. = 

 D. barklieusis H. Adams." This record and that of D. regia presum- 

 ably refer to the same species, but in that case the authors must have 

 been misled by the worn state of their -specimens into identifying 

 them with harkliensis — a well known and readily distinguishable 

 Mauritian species. 



Pieurotoma abbreviata Reeve. 



The Lifu form has been recently described by Sowerby as var. 

 lifuensis (Proc. Malac. Soc, 1907, p. 300). 



Rissoina catholica M. & S. (/. of Conch., viii., p. 306). 



R. zonula M. & S. (ibid. p. 308). 



Except for the rufous banding of ^. zofiula, I fail to see any differ- 

 ence between these two, after a careful examination of descriptions 

 and figures, and of examples in the British Museum received from 

 the Manchester Museum, and consider that they should be united. 

 Colour is never a constant characteristic in Rissoina, in species where 

 it occurs — e.g., in R. rugulosa Hutton, R. variegata Angas, and R. 

 fasciata A. Ad. The banded form may stand as var. zonula. 



Mr. Melvill fully agrees in the propriety of uniting these two species. 



Rissoina (Zebina) curta Adams (/ of C, viii., p. 119). 



The author's name should be 'Sowerby,' as given later on p. 412. 

 The prior name for this species is R. trideiitata Michaud. Mr. Mel- 

 vill is surely- right in considering JEuIima-deiitiens Dkr. the same species. 



Rissoia pyrrhacme M. & S. (I.e., p. 309). 



'i'his species has been made the type of Obtortio, a new sub-genus 

 of Odostomia (v. Hedley in Mem. Aust. Mus., 1899, vol. iii., p. 412 ; 

 and T3all cSr Bartsch's Mon. of West Amer. Pyramidellid Mollusks, 

 1909, p. 16). 



Syrnola jaculum M. & S. (/ of C, viii., p. 304). 



This is almost certainly identical with Odostomia aciailina Souverbie 

 mjoui-n. de Conch., 1865, p. 150, from New Caledonia. A specimen 

 of the latter, received from Mr. Sowerby, agrees in every respect ; 

 and I find that M. Bavay has also surmised the identity of these two 

 species. 



Syrnola violacea M. & S. (/. of C, viii., p. 304). 



Identical with Odostomia Ini/inioides Souverbie, which has priority.
