looked. More diligent search in favourable localities would probably 

 prove it to be more abundant. 



Its batliymetrical range in the British seas, so far as is known, extends 

 from extreme low water down to 50 fathoms. 



This species has been taken in the stomachs of Cod, Haddock, and 

 Plaice.

l'hyo7ie fimis is apparently rare in the Moray Firth. 



Only two specimens have been taken, at two localities, viz. Stations 

 X. and XIV., in from 19 to 42 fathoms, and one in the Cromarty Firth 

 between Invergordon and Alness Point, in 11 to 5 fathoms. 



The bathymetrical range of this species in the British seas is from 15 

 to 100 fathoms. 



It has been taken in the stomach of Haddock.

 Thyone raphanus is very rare in the Moray Firth, only one specimen 

 having been obtained, at Station XVI. So far as I am aware it has never 

 before been taken in this area, although it is not uncommon off the 

 Shetland Islands, and common on the west coast and in the lochs of the 

 Clyde area. 



Its bathymetrical range in the British seas extends from 20 fathoms 

 in Loch Fyue to 570 fathoms in the Faroe Channel. 



The head of this species has been found in the stomach of Cod, 

 Haddock, and Plaice.

Only one specimen of this species has been obtained by me in the 

 Moray Firth, at Station I., in 7 to 8| fathoms. P.-iolic-^ pJiantapii,^ has 

 not hitherto been recorded from this area. 



Its bathymetrical range extends from 7 to 127 fathoms.
