Habitat. — Sandy shore east of Burntisland. This species seems to be 

 rather uncommon within the Forth area. There does not appear to be 

 any previous record of it from the Forth. I obtained it by digging up 

 the sand down to 4 or 5 inches, and then passing the sand through a fine 

 wire sieve. It ' has been taken near Falmouth by Dr Leach ; at Moray 

 ' Firth by the Rev. G. Gordon ; on the coast of Cumberland by Mr 

 'Albany Hancock; and in Ox wick Bay by Mr Moggridge and Dr J. 

 * Gwyn Jeffreys.'* Mr David Robertson of Cumbrae records it as 

 ' moderately common all round our sandy shores near low water, and 

 4 taken most successfully by the sieve. 'f 



It will be observed from the references given that this pretty Amphipod 

 has received a considerable amount of attention from authors. Rev. Mr 

 Stebbing remarks (loc. cit.) \ 'The excellent name Sulcator might well 

 ' have been allowed to stand, but since that has been displaced on grounds 

 ' of priority, first by Pterygocera and then by Lepidactylis, it seems only 

 ' just to go back a step farther to Muller's Haustorius? I have adopted 

 this very reasonable proposal. 



Melphidippa (f) spinosa (Goes). 



1865. Gammarus spinosus, Goes, 'Crust. Amphip. Spitsb.' 



1870. Melphidippa spinosa, Boeck, 'Crust. Amphib. bor. et Arct.' 



Habitat. — Firth of Forth, west of May Island, taken with tow-net fixed 

 to the head of the beam trawl. This appears to be a rare species in the 

 Firth of Forth. It somewhat resembles Dexamine or Atylus. The one 

 or two specimens I have observed in the Forth were, when captured, of a 

 bright red colour, but from some cause none of them were perfect.
