 200 or 300 fry. The shells appear to correspond with the first 

 whorl of the style. 



Chemnitzia simillima, Ann. Nat. Hist. 3rd series, vol. ii. p. 128 ; 

 Sow. III. Ind. pi. 16. f. 3 (nom. C. pimlla). St. Catherine's Bay, 

 Jersey (Rev. A. M. Norman). The C. gracilis of Philippi does not 

 appear to have been hitherto found in Great Britain, although a 

 small and slender variety of C. elegantissima may have been mis- 

 taken for it. This variety has been figured by Sowerby (pi. 16. f. 2) 

 under the erroneous name of C. simillimus, referring to Montagu 

 and the C. gracilis of Philippi. The true C. gracilis is an exquisite 

 shell, and when taken alive it glitters in the sun like a bright needle. 

 In size and diameter it is less than Eulimella acicula.

O. glabrata, iii. 283. With the last ; but very rare. It has some-

O. diaphana, Jeff^r. in Ann. Nat. Hist. 2nd ser. vol. ii. p. 341 ; Sow. 

 III. Ind. pi. 17. f. 23. In dredged sand from Zetland; rare. Mr. 

 Sowerby justly remarks that this species is *' manifestly distinct " 

 from O. obliqua. 



Eulimella clavula, iii. 314. Guernsey; very rare. 



Natica Helicoides, iii. 339. I found a young specimen in dredged 

 sand from Belfast Bay. 



N. pusilla, iii. 341. Mr. Barlee has taken this species alive in the 

 Shetlands. 



Trichotropis borealis, iii. 361. In dredged sand from the Turbot 

 Bank, Belfast Bay ; and I have lately found it alive in the same part 

 of the Irish Sea. 



Cerithiopsis pulchella, Jeffr. in Ann. Nat. Hist. Mr. "Waller 

 has taken this unmistakeably distinct species on the north-eastern 

 coast of Ireland. It has been recorded in the Report of the Belfast 

 Dredging Committee (furnished to the British Association in 1857) 

 under the name of Cerithium metula. 



Nassa pygmaea, iii. 394. Belfast Bay {Mr. Waller). 



Buccinum Dalei, iii. 408. The operculum proves that this species 

 is a true Fusus ; and the shell wants the columellar fold of Buccinum. 



B. fusiforme, iii. 412. Mr. M*Andrew procured two specimens 

 (one of them being nearly adult, and the other younger) by dredging 

 off the coast of Finmark ; and the operculum, as well as the absence 

 of a columellar fold, clearly show that this species must also be re-
