Habitat. — Dredged in 12 fathoms, Inverkip Bay, 

 bottom shells, mud, and gravel; half a dozen were 

 taken in this haul. At Balloch Bay, Cumbrae, males 

 and females occurred in Zostera-beds near high- 

 water. Mr. John Smith, Kilwinning, has sent me 

 both male and female from the mouth of the 

 Garnock, among muddy grass, a little below high- 

 water mark, where the water is brackish. In this 

 situation, during floods, they must be subjected to 

 nearly pure fresh - water. Montagu found two 

 females adhering to the body of a Father-lasher 

 (Cottus scorpius). 



This species has been taken at Polperro, Plymouth 

 Sound, Devonshire, Falmouth, Bangor (Ireland), and 

 Isle of Man.
