indicated by the double line in the drawing of the second Gnathopod at 
p. 508 of the second vol. of 'Brit. Sess.-eyed Crust.,' can only be satisfac- 
torily observed with a moderately high power of the microscope, as a J or 
-1 inch objective. This species has been taken at Banff by Thomas 
Edward.

Habitat. — Sandy shore east of Burntisland. This species seems to be 
rather uncommon within the Forth area. There does not appmr 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 Oxwick Bay by Mr Moggridge and Dr J. 
' Gwyn Jeffreys.'* Mr David Robertson of Cumbrae records it as 
4 moderately common all round our sandy shores near low water, and 
' 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 Lepidadylis, it seems only 
' just to go back a step farther to Muller's Haustorius.' I have adopted 
this very reasonable proposal. 
Melphidippa (?) 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.
