128 Mr. Jeffreys oh British Mollusca. 



Aclis ascaris, iii. 219. Guernsey (Dr. Lukis & /. G. J.), Ply- 

 mouth. 



A. supranitida, iii. 220. With the last. Guernsey specimens 

 vaiy as to the number and disposition of the transverse striae, which 

 are sometimes wanting altogether, and at others are only present on 

 the upper whorls, although their total or partial absence has evidently 

 not been caused by friction. 



A.(?) unica, iii. 222. Guernsey (Dr.Luhs & Mr. Barlee). 



Stylifer Turtoni, iii. 226. I found a specimen, with the (dead) 

 animal in it, among some trawl-refuse from Plymouth, which con- 

 tained some of the Echinus sphcera ; and I am informed that several 

 specimens have been taken in the same locality. 



Eulima stenostoma, n. s. PI. V. fig. 7 a, h. E. subulata, var. ? 

 iii. 236. 

 Testa acuminata, hyalina, alba, fragilissima, glabra ; anfractibus 9, 



teretibus, gradatim increscentibus, ultimo reliquos sequante, supe- 



rioribus duobus obtusis, fascia pellucida ultimum prope medium, 



superiores juxta suturam, cingente ; sutura vix distincta ; apcrtura 



pyriformi, contracta, subtus effusa, superne acutangulaia ; peri- 



stomate in columellam subreflexo ; columella arcuata ; long. \,

Mr. M 'Andrew having obligingly presented me with one of his 

 Zetland specimens, I am enabled to offer the above description. He 

 has also taken specimens on the coast of Norway, which confirm the 

 idea of this proving to be a distinct species, as was surmised by the 

 authors of the 'British Mollusca.' It has somewhat the appearance 

 of a large Achalina acicula. 



Chemnitzia simillima. Turbo simillimus, Mont. Test. Brit. Suppl. 

 p. i;36, and Laskey, Mem. Wern. Soc. 406. t. viii. f. 15. Ch. 

 pusilla, Phil. ii. 224. t. xxviii. f. 21. Odostomia lactea ft, Jeffr. 

 Ann. N. II. vol. ii. n. s. p. 348. C/i. eleyantissirna, var., B. M. iii. 

 243. Torbay and Guernsey. Specimens from the last-named loca- 

 lity are sometimes toothed, as in Odostomia pro])er. It is very 

 distinct conchologically from any of the varieties of C eleyantissima, 

 and also malacologically, as Mr. Clark has observed. Montagu's 

 description of Turbo simillimus, that it resembles eleyantissimus, but 

 is less slender, and has fewer and more distant ribs, that are not 

 slanting or oblique, but straight and more arched, as well as larger 

 than the interstices, seems exactly to distinguish the two species. 



C. rufa, iii. 247 and iv. 276. Plymouth. 



C. indistincta, iii. 2J.5. In dredged sand from Guernsey. 



C. clathrata, iii. 258. ■ Mr. M'Andrew obtained a single specimen 

 at Orotava. It has a closer affinity to Odostomia interstincta than 

 to O. indistincta, but is evidently distinct from any of the varieties 

 of either of those species. 



Odostomia conoidea, iii. 260. Plymouth. 



O. consjiicua, iii. 263. I found a couple of fresh specimens in 

 dredged sand from Guernsey ; and Mr. Barlee procured another 

 from the same source. It is by far the largest of our Odostomice.
