Habitat. — Not uncommon in a few fathoms of 

 water on a sandy or sandy - gravelly bottom. 

 Dredged off the Tan Buoy, Cumbrae, in 7 fathoms, 

 bottom Melobesia; and between the Allans, in 2 to 

 3 fathoms, sand and gravel ; off Seamill, below 

 Portincross, Ayrshire, 6 fathoms, bottom sand and 

 stones. Also taken by the surface-net after sunset; 

 those so obtained during summer are generally small. 



On 16th December, 1886, they were taken very 

 abundantly in Millport Bay by the surface-net after 

 sunset, and were equally abundant a night or two 

 after. It was remarkable that, with a single excep- 

 tion, no other amphipod occurred in the gathering. 



It has been taken in the Moray Firth by Rev. G. 

 Gordon, and at Plymouth by Mr. S. Bate.
