112 Mr. Jeffreys on BritisJi Mollusca, 



Stylifer Turtoni, iii. 226. Mr. Norman questions this being found 

 on Echinus Sphcera ; and he says that Mr. xAlder has informed him 

 that all the specimens he had met with were from E. neglectus. 



Euhma nitida (Lamarck), Phil. i. 157 and ii. 134. I believe 

 the British shells which have been usually referred to this species 

 are specifically distinct from E. polita. Besides the subulate and 

 more regularly tapering form of the spire and the oblong (instead of 

 oval) aperture, which distinguish this species from E. polita, the 

 latter has (especially in young individuals) a faint keel on the lower 

 half of the last whorl. I have specimens from Zetland and various 

 other parts of the Scotch coast, as well as from Guernsey. A shell 

 sent by Professor Loven to Mr. Alder, under the name of " Evlima 

 nitida,'" and by the latter forwarded to me for examination, appears 

 to agree specifically with our shells, although Loven has not noticed 

 the JE. polita as a Norwegian species. 



E. stenostoma. A young specimen was procured by Mr. Barlee 

 in the Zetland dredgings. 



Chemnitzia scalaris, iii. 251. In dredged sand from Belfast Bay. 

 I am still of opinion that the C. rufescens of Forbes is merely the 

 northern form or variety, and that it ought to be reunited to this 

 species. 



Odostomia conspicua, iii. 263. Zetland {Mr. Barlee). 



O. Eulimoides, iii. 273; var. O. pallida, b. gracilior, anfractibus 

 productioribus, Jeffr. in Ann. Nat. Hist. (2nd series) vol. ii. p. 336 , 

 Guernsey and Zetland. I have given a representation of this pretty 

 variety in PI. III. fig. 18 a, b. 



O. Lukisii, n. s. PI. III. fig. \9 a,b.

Although I am very unwilling to swell the list of British Odosto- 

 mice with any more species, I cannot refrain from giving this, which 

 I beheve to be quite distinct from any of its numerous congeners ; 

 and Mr. Alder agrees with me in this belief. It has somewhat the 

 aspect of O. albella (which is certainly, in our opinion, not a variety 

 of O. JRissoides) in its shorter spire, much more convex whorls 

 (especially the penultimate one), and the peculiar introversion and 

 contraction of the peristome at its upper angle. From O. Rissoides it 

 differs in wanting the turriculate form of that shell, which is occasioned 

 by the great depth of the suture, and in its being more cylindrical, 

 as well as in the greater prominence of the penultimate whorl and the 

 contraction of the peristome. I have dedicated this species (without 

 permission) to Dr. Lukis, as a trifling mark of the esteem in which 

 I hold him as a scientific man. It is not verv uncommon in the
