MR. ROBERT GURNEY ON THE CRUSTACEA 
I am indebted to Dr. T. Scott for the identification of this 
species which he believes has not hitherto been taken on the 
East Coast though sometimes occurring in the South of 
England. I have found it at the Yacht Quay and Acle 
Bridge in the Bure and at Seven-Mile House in the Waveney. 
In the last two places it was in water rather brackish than 
salt. 
Stenhelia hispida, Brady. 
In the Waveney at Somerleyton Bridge, September 24th, 
1906. 
Delavaua palustris, Brady. 
In brackish pools on the marshes at Burgh Castle, and in 
Ploughman’s Ham by Lake Lothing. 
Canthocamptus palustris, Brady. 
I have already recorded this species from Oulton Broad, 
where it seems not uncommon. It has since been found at 
Acle Bridge, at Somerleyton Bridge (Waveney) and at Thurne 
Mouth (Bure). It is one of those brackish species which seem 
to prefer water almost salt, but it may be found in almost 
fresh water. 
Mesochra lilljeborgii, Bceck. 
Oulton Broad and Ploughman’s Ham, September, 1906, in 
water of very high salinity, and not accompanied by fresh- 
water species. 
Laophonte mohammed, Blanch, and Rich. 
In 1903 a single specimen of this rare species was found in 
the Muckfleet. Since then I have found it there twice, on 
one occasion in abundance. It has also occurred in the river 
at Acle in fresh water and in Heigham Sounds, so that it is 
a species capable of associating with fresh-water species. 
Nannopus palustris, Brady. 
On piles at Acle Bridge (June, 1906), in fresh water. 
Tisbe furcata (Baird). 
(For Tisbe in place of Idya, see Norman and Scott ‘ Crusta- 
cea of Devon and Cornwall,’ 1906.) 
Found only in Ploughman’s Ham, September, 1906. 
Cyclopina littoralis (Brady). 
,, gracilis, Claus.
