 srreenish-white.

Habitat : Woods, hedges, fields, gardens, and every- 

 where in the country, under stones and logs of wood 

 (especially when sunk deep in the ground or decayed), 

 as well as among moss and dead leaves, and at the 

 roots of grass in meadows (frequently after being irri- 

 gated), from Unst to Guernsey. Var. 1. Tawstock, near 

 Barnstaple (J. G. J.). Var. 2. Bath (Clark); Church 

 Stretton, Salop ; Clifton- Hampden, near Oxford ; Baw- 

 leigh, near Barnstaple ; Minlough Castle, Co. Galway ; 

 Dunboy, Co. Cork (J. G. J.). Var. 3. Dunboy (J. G. J.). 

 This and the last variety appear to be the variety ^ of 

 Nilsson. It has much the aspect of a distinct species, if 

 placed by the side of the typical form ; but they are con- 

 nected by intermediate gradations. Var. 4. Guernsey 

 (Lukis). Var. 5. Cardifi* (J. G. J.). This species is very 

 common in our upper tertiary deposits. It has almost a 

 world-wide range (or is what has been erroneously termed 

 "cosmopolitan^^), being found in Kamtschatka and on 

 the steppes of Siberia, in the South of Italy, Algeria, 

 Madeira and the Azores, North America, Cashmere and 

 Thibet, and probably in every other part of Europe, Asia, 

 Africa, and America.
