1. Cletodes limicola, nov. sp. PL XXI.. figs. 10-17. 



Animal, when seen from above, elongated, distinctly indented 

 at each ring of the body. First segment of cephalothorax short, 

 about equal in length to the two following ; second and third ab- 

 dominal segments produced into spinous processes at the lower 

 lateral angles. Upper antennae in the female much shorter than 

 the first cephalothoracic segment ; first three joints short, and 

 nearly equal, fourth about half as long as the third, fifth as long 

 as the third, but much more slender ; in the male forming at the 

 third joint a large vesiculiform swelling, last joint elongated and 

 uncinate. Swimming feet elongated, slender ; the outer branch 

 ciliated on the margins, bearing at the apex of each joint, on the 

 external margin, a long slender spine, terminal spines long and 

 slender; the middle joint has also a long apical seta at the inner 

 margin : inner branch two-jointed, the first joint very small, the 

 second long, almost filiform, and dividing at the extremity into 

 one short and two very long lash-like branches. Fifth foot in 

 the female foliaceous, the outer branch rather the longer, bearing 

 one long seta at the apex and three shorter ones on the outer 

 margin, inner branch with two long apical sette ; in the male the 

 two branches are of nearly equal length, very narrow, simple, 

 one branch bearing one, the other two long setas at the apex. 

 The caudal segments short, but longer in the male than in the 

 female, setse one on each segment, scarcely longer than the seg- 

 ment itself. Length, g^-rd of an inch. 



Hob. — Off Seaham Harbour in a depth of twenty to thirty 

 fathoms, on a soft muddy bottom. Two specimens only taken. 

 On account of the peculiar structure of the swimming feet, which 

 were identical in both examples, I think I am justified in refer- 

 ring these to the male and female of the same species. The 

 genus approaches Lilljeborgia of Claus, but the characters given 

 by that author, " Pedum sequentium (2, 3, 4), rami interni rudi- 

 mentarii, rami externi triarticulati, uncinati," do not apply here.
