Philoscia couchit is an inhabitant of the sea-side; it is smaller 
than the last species, its colour to the naked eye 
is a uniform lead-grey, and its antennz are very 
large (compared with its size) and hairy. 
This species was discovered by Professor 
Kinahan when in the company of Messrs. Bate 
and Westwood near Polperro in Cornwall in 
the year 1858, and dried specimens presented 
by him are in the British Museum (Natural 
History).
