Habitat. — On two different occasions after a storm 

 a single specimen was found in small pools near 

 low - water, west side of Karnes Bay, Cumbrae. 

 Both were alive when taken, but in a very weak 

 state, having most likely been brought in from 

 deeper water by the storm. Also dredged at the 

 mouth of Loch Fyne, in 37 fathoms, bottom mud 

 and small gravel; and off north side of Little Cum- 

 brae, in 29 fathoms, mud and dead shells ; and on a 

 dead fish in a bait-pot — leaving no doubt that this 

 species is another of the scavengers of the deep. 



The bodies of those taken from the shallow and 

 deeper water were smooth, and closely studded 

 with small dendritic-like markings. The eyes are 

 subquadrate, with large facets placed in rows. The 

 middle tail-plate (telson) has three spines on each 

 side ; the inner tail-plate has three or four on each 

 side, with one terminal spine ; the outer plate has 

 four on the outside, with one terminal bent spine. 

 All the plates are fringed with plumose cilise, and 

 all the fingers are tipped with dark brown. 



It has been taken in Dublin Bay by Mr. Warren, 

 also off the Yorkshire coast, and at the Moray Firth 

 by Mr. Gregor.
