var. glabra Verk.^ — New to Britain. Off the Shetlands, 155^ 

 (Scottish Fishery Board) ! This was first recorded from Finmark by 

 Mr. T. A. l^erkriizen. My specimens are small and thin, the epider- 

 jpis very delicate, silky, and highly polished, resembling gold-beater's 

 skin, and the spiral stria: slight or totally absent. I have three 

 specimens trawled from deep water in the Shetlands, and their 

 appearance suggests a habitat in deep and still water, on fine sand or 

 mud. Canon Norman dredged a small form of it at Drontheim, 

 which is figured in the "Annals" for Nov., 1893, and Mr. James Simp- 

 son has many specimens procured from the north side of the Shetland- 

 Faroe Channel, 6o-7of. ! The original Finmark specimens, of which 

 Sars' figure is a good representation, have an unusually short base and 

 canal, somewhat similar to F. airtiis ]e^L, from North America and the 

 Crag, but those characters are not uniform in this variety. 



I do not know of any good typical figure of this common shell. 

 Shetland specimens of 7^ gracilis (as in the last species and the next) 

 are more slender than usual, and Gwyn Jeffreys figures this slender 

 form as his type; Sowerby figures an immature shell, the base being 

 angulated in consequence of the last whorl not being fully developed; 

 while Forbes and Hanley describe as their type " the beautiful slender 

 form that is most connnonly preserved in cabinets," but their figures 

 illustrate the vars. belliana and convoluta. Mr. Tomlin's collection 

 contains a reversed example. Specimens of this and the next species 

 are occasionally dredged which are denuded of the epidermis and 

 apparently dead and water-worn, yet still containing the animal and 

 operculum. As I have explained with regard to examples oi Trochits 

 in a similar condition, these have been swallowed by fish and voided 

 again, the action of the gastric fluid having meanwhile destroyed the 

 epidermis, 



F. propinquus Aid. — Not Dublin Bay nor Cork, which 

 localities belong to the next species (Jeffreys); Birkdale (Heathcote); 

 Llandulas (Archer); St. Andrew's (M'Litosh); off Peterhead 60 f. 

 (Triton) ! ^Vest Orkneys 45 f.; and North Rona. In the Report of 

 the 'Valorous' Expedition, Gwyn Jeffreys has mistakenly recorded this 

 species from the Bay of Biscay 109-1380 f., by the 'Porcupine' Ex- 

 pedition of 1870, instead of from the West of Ireland, Stations 24 

 and 30, by the expedition of 1869 ; and Canon Norman has also 

 mistakenly recorded it from N. of Hebrides, 189-530 f, 'Porcupine' 

 1869, instead of ' Lightning' Expedition, 1868.
