BEVISED REPOET ON L.M.B.C. COPEPODA. 89 



In a former paper " Second Eeport on the Copepoda 

 of Liverpool Bay," Proc. Biol. Soc, L'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 is provided with swimming setae and is two 

 jointed," and he so figures it. This accidental error led 

 M. Canu in " Les Copepodes libres 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. bonnier i. On 

 examining my specimens of I. clavipes I found they agreed 

 with Canu's I. bonnier i, and on the matter being referred 

 to Dr. Brady he at once saw that Canu's drawing is correct 

 for I. clavipes. I. bonnieri must therefore be withdrawn. 

 Centropages hamatns, Lilljeborg. (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 I am aware the allied species G. typicus has never 

 been found in the L.M.B.C. district. 



Parapontella brevicornis, Lubbock. (PL XVI, fig. 4.) 

 Length 1.30 mm. Occasionally taken in surface townet 

 also rarely in tidal pools. The two lateral abdominal 

 spines (c) easily distinguish this species. 



Family II. — PoNTELLiDiE. 



Labidocera wollastoni, Lubbock. 



Length 2.50 mm. During the autumn months we 

 have taken this somewhat rare species plentifully in sur- 

 face townets off Puffin Island and in the open sea. Males
