RARE CRUSTACEA 
ON THE YORKSHIRE COAST. 
Rev. Canon A. Mert—E NORMAN, M.A., D.C.L., F.R.S., Etc. 
Mr. RoEsuck sent me, in February, some Amphipoda which had 
been received by him from Mr. Thomas H. Nelson from Redcar, and 
requested me to examine them. Mr. Nelson stated that there were 
‘millions of them in the sea’ in the second week of February, and 
that they were affording food to thousands of Kittiwake Gulls. 
These Amphipodous Crustacea were Euthemisto compressa (Gées), 
which is one of the family Hyperiide. I am not aware that this 
species has before been noticed in the British seas. It is an Arctic 
form, which has been found off the coasts of Norway, Finmark, 
Jan Mayen, and Greenland. 
The specimens thus sent to me had been dried and pressed 
between paper, and in replying to Mr. Roebuck, I regretted that 
they had not been preserved in spirits of wine. The result was that 
Mr. Nelson, on the 4th of April, collected some specimens which 
had been cast up on the sands and sent them in spirits. Mixed with 
the Euthemisto compressa then sent were other Crustacea of much 
interest. There was a cast skin of Lepidactylis arenaria (Slabber) = 
Sulcator arenarius Bate & West. ; showing that that species lives in 
the sand between tide-marks at Redcar. But much more important 
were mutilated specimens, but enough for positive identification, 
of two oceanic species of Schizopoda, which had been washed 
in with the Sane The Schizopoda belong to the family 
Euphausiidz,* ar 
Daca iedidieciatite (Kroyer).

This delicate little ‘shrimp’ has been found in the seas ot 
Greenland, Norway, and Finmark ; and I determined specimens 
which were taken in the Faroé Channel by the ‘Triton’ in 1882.
