There are three figures — one of the natural size, the second a 

 lateral enlarged view, being that given in F. & H., the third 

 taken from below ; but a point of especial interest is that at 

 one corner of the cardboard are still to be seen traces of a 

 yellow stain, underueath which is written " stain of the 

 mucus." " The mucus (this character is especially to be 

 noted) is orange-coloured" {F. tfc //.). 



North Mavine, Shetland, on stones in a watercourse of a 

 mountain rill {Jeffreys), 



Subgenus Amaxia, Moq.-Tandon. 



184. Limax carinatus, Kisso, = L, margrnatus, Drap, & Jeffreys 

 (non Miiller). 



185. Limax ga^ateSj DrapsLTmrnd, 



This is generally considered a rare species ; but I have 

 found it more frequently than the last, and described it many 

 years ago {'Zoologist,' 1853, p. 4018). I have had speci- 

 mens from St. Martin's, Guernsey ; Torquay ; Tenby ; several 

 places in the county of Durham, inchiding my own garden 

 here ; Cumbrae, N.B. ; Killarney, Ireland. 



Genus 2. Vitrina, Draparnaud. 



186. Vitrina pellucida (Miiller). 



Genus 3. CONULUS, Fitzinger. 



187. Conulus fulvus (Miiller). 



A species apparently of more extensive distribution than 

 any other land-shell — the whole of Europe, North Africa, 

 the Azores, Western Asia, Siberia, Central Asia, whence it 

 is recorded by von Martens. I cannot find the slightest 

 difference when shells of the American Helix chersina^ Say, 

 are placed beside European fulvus^ and that shell ranges from 

 Alaska to Florida, Hudson's Bay Territory to California and 

 Texas. Most authors make H. chersina a synonym of G. 

 fulvus ) but Dall (Proc. U. S. Nat. Mus. 1885, p. 271) 

 writes : — " This species will probably be found identical with 

 Z. fulvus ; but as the name of fulvus is not uncontested and 

 there seems to be some discrepancy in observations of the 

 soft parts, I prefer to retain Say's name." 



Genus 4. Hyalinia, F^russac. 



188. Ilijolinia crystalUna (Miiller).
