REVISED REPORT ON L.M.B.C. COPEPODA. 183 
In a former paper “Second Report on the Copepoda 
of Liverpool Bay,’ Proc. Biol. Soc., Li’pool, Vol. II, I 
pointed out the existence of a pair of curved spines trifid 
at apex, one on each side of the tubercular genital pro- 
longations on the first abdominal somite of the female. 
Brady’s drawing and description of the fifth foot of the 
male are not quite correct. He says the inner branch ‘ of 
the right side 1s provided with swimming sete and is two 
jointed,” and he so figures it. This accidental error led 
M. Canu in “ Les Copepodes bres Marins du Boulon- 
nais,’ (Bulletin Scientifique de la France, Paris, 1888) to 
suppose that a male specimen he examined differing in 
the fifth feet from Brady’s drawing could not be I. 
clavipes and he accordingly named it I. bonniert. On 
examining my specimens of J. clavipes I found they agreed 
with Canu’s J. bonniert, and on the matter being referred 
to Dr. Brady he at once saw that Canu’s drawing is correct 
for I. clavipes. I. bonniert must therefore be withdrawn. 
Centropages hamatus, Liljeborg. (Pl. XVI, fig. 3.) 
Length 1.30 mm. Common in the open and seldom 
absent from the townets. It is rather surprising that so 
far as 1am aware the allied species C. typicws has never 
been found in the L.M.B.C. district. 
Parapontella brevicornis, Lubbock. (Pl. XVI, fig. 4.) 
Length 1.30mm. Occasionally taken in surface townet 
also rarely in tidal pools. The two lateral abdominal 
spines (c) easily distinguish this species. 
Family II.—PonTELLIDZ. 
Labidocera wollastont, Lubbock. 
Length 2.50 mm. During the autumn months we 
have taken this somewhat rare species plentifully in sur- 
face townets off Puffin Isiand and in the open sea. Males
