134 BRITISH PAKASITIC C0PEP0DA. 



against the lower spoon-like process forms a rounded 

 apical expansion. Both rami in the first pair of 

 thoracic legs distinctly two-jointed and moderately 

 stout, the inner ramus, which is larger than the outer, 

 sparingly fringed with minute setae and provided with 

 two apical spines of unequal length ; the outer and 

 shorter ramus with a fringe of minute setae on the 

 outer margin of the first joint, the end joint bearing 

 several spines round its outer margin and apex, the 

 inner spine of moderate length but the others small. 

 The second pair with a general resemblance to those 

 of both Eudactylina acuta and En. similis ; the inner 

 ramus, which is distinctly three-jointed, considerably 

 smaller than the outer one, and the first joint having 

 a longitudinal row of small spines extending obliquely 

 upwards from near the distal end of the outer margin, 

 while the end joint bears two small apical spines of 

 unequal length ; the outer ramus stout, tolerably 

 elongated and indistinctly three-jointed, end joint 

 small, about as broad as long, and bearing a spiniform 

 seta on its margin and two minute prickles on the 

 rounded apex ; two short spines, each with a thickened 

 base, springing from near the distal end of the outer 

 margin of the first joint, this joint being elongated 

 and slightly arcuate ; a pseudo-articulation may be 

 noticed between the two short spines and extending 

 partly across the joint. The third and fourth pairs 

 nearly alike and resembling those of Eudactylina 

 similis except that the inner rami have a number of 

 scattered spinules on their outer aspect ; the outer 

 rami each rounded at the extremity and carrying a 

 single elongated terminal seta ; the} T are also provided 

 with a few small spines on the outer margin of the 

 second and third joints, while a fringe of minute prickles 

 extends along the margin of the first joint. The fifth 

 pair, which are broadly foliaceous, ornamented with 

 several transverse rows of minute spines and also 

 furnished with three apical setae. Caudal rami short, 

 about as long as the last abdominal segment, and bear-
