240 VELUTINID^. 



Orkneys (Goodsir and Forbes), Tresta Voe, Shetland 

 ( J. G. J.) ; no less rare than local. Scandinavia (Miiller 

 and others); Iceland (Steenstrup) ; Greenland (Morch) ; 

 Kamptschatka (Steller, fide Middendorff ) , and perhaps 

 the Kurile Islands (Pallas) . 



Lives in company with V. lavigata. Both seem fond 

 of floating, and of getting out of the water if confined 

 in a vessel. The middle plate of the tongue in the pre- 

 sent species is much deeper and proportionally narrower 

 than in V. lavigata ; and it has fewer notches, the 

 central one of which does not extend half way down, 

 instead of to the base as in the other species ; and the 

 first side-plate has no claw, nor are the second and third 

 pleurae so long or so much incurved. 



It is perhaps the Helix coriacea of Pallas, and un- 

 doubtedly the Bulla flexilis of Montagu. Miiller's de- 

 scription is not less full and precise than that of his B. 

 velutina, the identity of which, as the type of this genus, 

 has never been questioned. Gray raised the present 

 shell to generic rank as Velutella.
