18 Mr. J. G. Jeffreys on some British Shells. 



the whorls more produced, occurred to Mr. Barlee and myself 

 while dredging off the coast of Skye. 



I suspect that the "young specimen ofBuccinum ovum" stated 

 by Mr. King in the ' Annals ' for May, to have been procured 

 by him from the Northumberland coast, is the Buccinum Hum- 

 phreysianum, which in its young state it somewhat resembles. 

 Having the opportunity of comparing a young specimen of each 

 of those shells, I venture to make this suggestion. The Halia 

 Flemingiana of Macgillivray (p. 189) is a young shell of the Buc- 

 cinum ovum. 



Mr, Barlee has informed me that he got Velutina fleocilis in 

 Loch Fyne and not at Skye, and Emarginula crassa at Oban 

 (where I believe Mr. Alder had previously found it), as well as in 

 the other localities mentioned in my last paper. 



A few valves of Terebratula seminulum (?) lately occurred to 

 Mr. Barlee and myself by dredging off Skye. 



Tellina pygmcea (Phil.), Loven, p. 42. In deep water from 

 several parts of the western coast of Scotland as well as from 

 Cornwall. 



Tellina pro ocima> Wern. Mem. viii. p. 105. pi. 1. f. 21 ; Macg. 

 p. 340. A single but fresh valve, having the epidermis on it, 

 was found by Mr. Barlee and myself in dredging off Skye from 

 about fifty fathoms water. 



Clausina*, n. g. 

 Testa pygmsea, orbicularis aut longitudinaliter rotundato-ovata, glo- 

 bosa, subsequilateralis, sequivalvis, utrinque clausa, plerumque te- 

 gumine ferruginoso vestita. Cardo in utraque valvula tuberculo 

 et lamella laterali munitus. Apices subcentrales. Lunula nulla. 

 Ligamentum externum. Musculares impressiones ut in Cyprina. 

 Profundum maris incolit. 



This genus differs from Kellia and Poronia in having only 

 one cardinal tooth in each valve, and the ligament being external 

 instead of internal. 



Sp. 1. Clausina ferruginosa. Kellia ferruginosa, Yorhes, Brit. 

 Assoc. Rep. 1843, p. 192. Artemis ferruginosa, Jeffr. in Ann. 

 of Nat. Hist. 



Sp. 2. CI. abyssicola. Kellia abyssicola, Forbes in loc. cit. A 

 few specimens (mostly single valves) were found by Mr. Barlee 

 and myself with the last, by dredging in fifty fathoms water off 

 Skye. 



It differs from the first-named species in the greater convexity 

 of the shell, the beaks being much more prominent, having a 

 slight sinus on the front margin, and its chalky white colour. 

 One specimen was partly covered with the ferruginous crust.
