PHILOSCIA MUSCORUM. 451 
Tuts species is smooth and shining, generally of a 
fulvous colour, with dark black patches and white spots. 
The head is transversely elliptical and arched in front, 
being destitute of any lateral or median lobe. The 
internal antennz are small and inconspicuous; the outer 
antennee are cylindrical and setose. The tail is much 
narrower than the terminal segments of the body, with 
the last ring broadly triangular, its apex being acute, 
and its terminal appendages having the outer division 
elongate-trigonate, spinous along its lateral margins; the 
inner lobe nearly as long as the latter. 
The species runs with great rapidity, and seeks the 
sunshine. Jt is widely distributed, and very common. 
It prefers dry rather than-damp situations, under leaves, 
stones, and moss; also near the sea-shore. It is found 
abundantly throughout the southern part of England. 
Professor Bell found it under stones at Cheriton, and 
observes in his manuscript notes—‘“ I found it of every 
shade of colour, from rich black to reddish brown and 
light green. It is more active than any other species, 
and the crust is more tender, and easily injured.” Add- 
ing—“I believe colour to be absolutely valueless as a 
specific character in the whole of the Oniscide.” 
Dublin, Wicklow, Meath, Wexford, Cork, Waterford, 
and Tyrone, have been recorded as Irish localities.
