a variety of Tiirundo. C. Kieneri, Hidalgo, therefore becomes a 

 synonym of C. hirundo, Linn. 



I may add that I consider the C. coffea, Sow.,^ a distinct species 

 and not a variety of C. hirundo, as stated by various monographers. 

 This opinion is based on the difference of shape, colour-marking, 

 and particularly on the teeth being finer and extending over the 

 posterior extremity. 



Cypr^a Prestoni, n.n. for C. interrupta, Gray.^ 



The name of this species has to be changed, Bolten^ having 

 previously used the same term. The C. interrupta, Bolten, is a 

 nomen nudum, there being no description or figure given or even 

 cited. Although Eolten's name is useless, Gray's designation, having 

 been used before, cannot stand, and therefore I have much pleasure 

 in naming this shell C. Prestoni after my friend Mr. H. B. Preston. 



Cyph^a HiDALGor, n.n. for C. leucostoma, Gaskoin.* 



The specific name leucostoma had been used by Gmelin ^ to designate 

 a species which Roberts says equals C. lynx, Linn. Dillwyn 

 considered it a synonym of C. Vanelli, Linn., which is C. lynx, 

 Linn., juv., and according to Hidalgo it is the C. picta. Gray (?). As 

 this species has no synonyms, I propose to rename it C. Hidalgoi, 

 after the author of the recent excellent monograph of this genus. 



CypR^A LoEBBECKEANA, Wciukauff.^ 



This shell has generally been considered a variety of C. carneola, 

 Linn., without the purple-coloured teeth which are characteristic of 

 that species. In the Thesaurus (fig. 322) Sowerby illustrates a shell 

 which is supposed to be the same, a C. Loehheckeana. It is true that 

 the teeth of the specimen illustrated are white, but it is also distinctly 

 three-banded and of a cylindrical shape, and is clearly only a variety 

 of C. carneola. C. Loebheclceana, on the other hand, is pyriform, of 

 a uniform pale yellow colour, without any bands, with a white base, 

 and a ridge on the outer edge of the columella. The teeth on the 

 columella lips are long and fine, and are interrupted below the ridge, 

 leaving a gap. In my opinion this shell is not a variety of C. carneola, 

 but a good species. Hidalgo makes the shell under consideration 

 a variety of C. vitellus. Through the kindness of Mr. E. A. Smith 

 I have been able to examine some pale yellow varieties of C. vitellus 

 in the British Museum, but failed to see the slightest resemblance to 

 C. Loelbeckeana. 



Weinkauff, in his note on this species, says he has inspected 800 

 specimens of C. carneola, but could not link up Loebheclceana with them. 



Until we have further proof and more specimens of this shell are
