 angle at its inner extremity, and the flagellum consists of 

 five slender articuli. These organs are destitute of the 

 spines which distinguish the other species. The terminal 

 segment of the tail is triangular, truncate at the ex- 

 tremity, very nearly straight and deeply furrowed above, 

 but not emarginate. The caudal appendages are trigono- 

 subulate. 



Taken not uncommonly under stones and moss on hills 

 at Portlaw, in the county of Waterford, by Dr. Kinahan,

 snow. It runs with great agility, and does not bury 

 itself deep in the earth like Ph. riparia.
