REVISED REPORT ON L.M.B.C. COPEPODA. 197 
Length 0.80 mm. A few specimens all females were 
recently dredged with mud in Port Erin Bay. 
Delavalia palustris, Brady. (Pl. XX, fig. 2.) 
Length 0.80 mm. Several of this mud loving species 
have been found in mud taken about Puffin Island, Port 
Erin, Garth Ferry, and Hale. Among them is one male 
which so far as I am aware has not been hitherto known. 
Delavalia refieca, Brady and Robertson. (Pl. XX, fig. 3.) 
Length 0.70 mm. One specimen a female was dredged 
in 20 fathoms in Redwharfe Bay, Anglesea, and one male 
was found in mud from Garth Ferry taken at low water. 
Mesochra lilyeborgu, Boeck. (Pl. XX. fig. 4.) 
Taken by townet off Puffin Island, also found in mud 
taken in a brackish tributary of the Mersey at Hale. 
Paramesochra dubia, Scott. (Pl. XX VII, fig. 8. a.) 
Length 0.65 mm. Quantities of this species recently 
. described and figured by Mr. Thomas Scott, F.L.S. 
| (Tenth Annual Report of the Fishery Board for Scotland) 
| J found in mud dredged at 7 fathoms in Port Erin Bay, 
males and females being equally plentiful. Since then I 
find it in mud collected by Mr. Corbin from the Duddon 
cockle beds at the mouth of the River Duddon near 
Barrow. 
Tetragoniceps bradyi, Scott. (Pl. XXVII, fig. 8. b.—f,) 
Length 1mm. Found only at same times and habitat 
as the last named species, (Paramesochra dubia) Scott 
found no males; they were however plentiful in the Port 
Erin gathering. The conspicuous 5th feet (c) at once 
render the female of this species recognisable. 
Diosaccus tenwicornis, Claus. (Pl. XX, fig. 5.) 
Length 1.30 mm. Found in rock pools at Hilbre and 
Puffin Islands, and dredged in Port Erin Bay. It is 
distinguishable by its long anterior antenne (q).
