18 BRITISH COPEPODA. 
short and armed with numerous setz of moderate 
length. Lower foot-jaw (fig. 7) 3-jomted; first joint 
short and stout, second rather longer and having a 
pectinate series of small cilia near the middle; last 
joit very short and armed with three strong, curved, 
and plumose sete at the apex. The outer margins of 
all the joints of the first four pairs of feet (fig. 8) are 
fringed with spines, and their longer setz have pec- 
tinate margins. Fifth pair of feet small (fig. 9), the 
basal joint triangular and bearing two lone sete on 
the inner and one on the outer angle; second joint 
smaller, subquadrangular, bearing four sete, two of 
which are of equal length with those of the basal 
joint ; the other two much shorter. 
I have seen only very few examples of this species, 
not more than a dozen; these were taken off Porcressa 
Bay (Scilly Islands) in a depth of twenty fathoms, and 
off Hartlepool in twenty-five fathoms on a sandy 
bottom. M. Boeck’s specimens were found in com- 
pany with the previous species, Zosime typica. 
There may, perhaps, be some doubt whether the 
species here described is rightly referred to M. 
Boeck’s Bradya typica. In some points the two 
appear to differ, the only important divergence being, 
however, as to the number of joints on the inner 
branch of the posterior antenne. But this is a pomt 
upon which a mistake may very readily be made; 
indeed it is one by no means always easy of determi- 
nation, even when attention is specially directed to it. 
I regret that an insufficient supply of specimens has 
prevented my satisfying myself as to this particular,
