Philoscia couchii 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 antennae 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).
