Animal bluish-gray, head black ; the mantle edge bluish-gray, 

 densely black-speckled ; the hind part of the foot pale gray. The 

 lobe of the mantle very small, by which latter character, and the 

 smaller number of whorls, it is distinguished from Vitrina pellu- 

 cida, Mull. (Moller MSS.)

Fabricius found first a species of Vitrina " in Archangelica ;* 

 alibi non villi." One of the two specimens in the collection of 

 Fabricius was sent, with the permission of King Christian, to 

 Ferussac, who declared it differed from any species known to 

 him ; but I do not know if it is mentioned in his works. The 

 botanist T. Vahl rediscovered it " inter muscos " 1829. Moller 

 states that he has found it in the same localities as the two fol- 

 lowing species, and besides on sunny mountain declivities, where 

 the water dives down, where a rather luxuriant vegetation of 

 Angelica, Alchemilla and moss is found. Angelica archangelica 

 is, however, no necessary condition for its Habitation, as Fabri- 

 cius seems to think, as 1 often have found this shell on places 

 where this plant is not growing. It looks for its winter quarters 

 when the night frosts commence to be steady, under large stones, 

 and freezes probably sometimes to death, as under such stones 

 are often found many dead and bleached shells. Others burrow 

 themselves in the earth. 



Near the hot springs of Godhavn (Obik). 



It is specially found on the sunny side of the mountain slopes, 

 where the wind prevents the snow from accumulating. 



This shell is very like Vitrina beryllina, C. Pfr. (= V. pellu- 

 eida, L. Pfr., not Miiller, which looks to be V. annularis, Fer., 

 t. 9, f. 7)* It is, however, more convex, and the spire is more 

 elevated.
