10 Mr. G. S. Brady on the Non-parasitic Marine Copepoda 



thrice as long as broad ; setae short, ciliated, jointed in the 

 middle. Length -,V of an inch. Colour dark brown. 



lldh. Amongst I'uci near low-water mark between Ilyhope 

 and Sunderland. Two or three specimens. 



Tliis apjjroaehes very closely the genera Onata^ Philippi, 

 and Antaria, Dana, but does not seem strictly refcral)le to 

 either of them. Probal)ly, indeed, the two are synonymous. 

 One of my specimens differed in some minor points from the 

 others, whence I supposed it to be of different sex, and have 

 so described it here. The species, however, requires further 

 examination. 



Fam. Harpactidae. 



Genus LoNUirEDiA, Claus. 



Lomjipedia coronata^ Claus. 



This beautiful species occurred abundantly on a sandy 

 bottom off Seaton Carew, in a depth of four fathoms, also off 

 Sealiam Harbour (twenty to thirty fatlioms), and among weeds 

 near the nell-Rock Lighthouse. Mr. Norman finds it in 

 Shetland; and I have myself taken it on the west coast of 

 Ireland. 



Genus EcTiNOSOMA, Boeck. 

 Ectinosoma melaniceps, Boeck. PI. V. figs. 1-12. 



Off Seaton Carew and Seaham Harbour, in com[)any with 

 the foregoing species, but less abundantly. 



The characters of this remarkable species are so distinct 

 that I camiot doubt its identity with that described by Boeck, 

 tiiough 1 have not noticed any thing in my sj)ecimeTis which 

 warrants the term nielaniccps. Moreover the fifth foot con- 

 sists of two branches, and not of one only as stated by that 

 author, unless, indeed, the Norwegian animal be a different 

 but closely allied member of the same genus. 



Genus Taciiidius, Lilljcborg. 

 Taclddiiis hrevicornis (Muller).
