30 BRITISH COPEPODA. 



swimming-feet are nearly equal in length, but the 

 branches of the first pair (fig. 8) are only 1-jointed, 

 and their marginal setae are comparatively short; 

 branches of the three following pairs slender, the 

 outer branch (fig. 9) having two apical spines, one 

 long and one short ; setae of the inner margins long 

 and slender. Fifth pair in the female foliaceous, 2- 

 jointed, bearing a few marginal setae (fig. 10), the 

 joints nearly equal in length; in the male (fig. 11) 

 1-jointed, elongated, curved, bearing two long setae at 

 the apex, and one on the outer margin. Colour deep 

 yellowish brown. Length -g^rd of an inch ('77 mm.). 

 Dredged in twenty-five fathoms four miles off 

 Marsden (Durham) amongst rough sand ; in thirty-five 

 fathoms off Robin Hood's Bay (Yorkshire), amongst 

 Filagrana implexa, and off Red Cliff (Yorkshire) : 

 Oban (Rev. A. M. Norman). The Rev. A. M. 

 Norman also records the occurrence of " A. falcata" 

 which I believe to be properly referable to this species, 

 " amongst Laminarice in Bressay Sound " (Shetland). 

 Dr. Claus's specimens were found at Heligoland and 

 Naples, and Boeck's at Christiania.
