Mr. J. G. Jeffreys on British Mollusca. 47 



wfts one of the captors of this prize, in company with Dr. Dickie 

 anil Mr. Ilyndnian, and that all the specimens (ahout a dozen in 

 nnmber, of' different sizes) were taken, in one hanl of the dredge, 

 from the Tnrbot-bank, a little north of the mouth of Belfast Bay, at 

 a depth of about L'O fathoms. All the specimens appear to have 

 l)cen much water-worn, and deprived by friction of nearly every trace 

 of those basal grooves and apical ribs which are observable in fresh 

 specimens. The spire is rather shorter, and the whorls consequently 

 are more swollen than in Norwegian specimens which are to be seen 

 in the British Museum ; Mr. M'Andrew having also kindly sent me 

 some from the North Sea. The typical form appears to be allied to 

 the liuccinum minus of Philippi. 



Fnsus antiqnus, iii. 423. Barmouth. This appears to be the 

 southernmost known limit for this species, as well as the northern- 

 most for Venus chione. 



Mangelia sejitangularis, iii. 4r)8. Barmouth. 



M. scabra (M. linearis, var.), iii. 4/0. Shetland sand. (See 

 Ann. vol. xvii. p. 18/.) 



M. attenuata, iii. 488. Barmouth. 



Gasteropoda Opisthobrancliiata. 



Cylichna strigella, iii. 518. Arran Isle, Galway (Barlee). 



Amphispliyra globosa, Lov. Ind. Moll. Scand. Occid. p. 11. 



A single specimen only was discovered by Mr. Barlee in dredging 

 off Skye last year. It agrees fairly with Loven's description ; but 

 he has not noticed the delicate, liexuous, longitudinal grooves which 

 are diseernibls under a high magnifying power. The colour of the 

 shell, when covered with the epidermis, is rufous brown. Owing to 

 its expanded aperture, it has somewhat the appearance of a Velutina. 

 As it has not yet been figured, I thought a drawing (PI. II. fig. G) by 

 that excellent and accurate artist, Mr. J. de C. Sowerby, would be 

 acceptable.
