Echinocardium Jlaveseens is a rare species in the Moray Firth, so far 

 as my observations have extended. I have taken six specimens, at four 

 of the special stations farthest from the coast line, in 30| to 42 fathoms. 

 It appears to be absent altogether in the Cromarty Firth. 



The bathymetrical range of this species extends from 53 to 140 

 fathoms ; its natural habitat, however, is confined to depths between 40 

 and 100 fathoms, and on a bottom deposit of shell-sand and ooze. 



Echinocardium Jlaveseens has been found in the stomachs of Haddock 

 and Cat-fish.

Brissopsis lyrifera is not an uncommon form in the Moray Firth, but 

 it is confined to the farthest off-shore waters in the greatest depths, on a 

 bottom deposit of homogeneous mud. I have taken this species iu 

 moderate numbers at five of the special stations, near Smith Bank, in ^4 

 to 42 fathoms. It was not found in the Cromarty Firth. 



The bathymetrical range of this species, in the British seas, extends 

 from IOC?) to 200 fathoms. In the Southern Atlantic, however, it is 

 found in great depths. It was obtained by the Challenger Expedition off 

 the American coast, in a depth of 1555 fathoms. 



Brissopsis lyrifera has been found in the stomachs of Cat-fish, Cod, 

 and Conger.
