REPORT ON THE COPEPODA. 51 



with club-shaped, sensory filaments (fig. 2). The inner branches of the first four pairs 

 of feet are very short and three-jointed (fig. 6), the terminal spines of the outer branches 

 are of moderate breadth, sword-shaped, and very minutely serrated on the inner edge 

 (fig. 7). The fifth pair of feet in the male (figs. 8,9) have on both sides a stout, two-jointed 

 stalk, the terminal branches being three-jointed in the left foot, and two-jointed in the 

 right ; the second joint of the peduncle on the left side has the inner margin produced 

 into a large five-toothed quadrate lamina, that of the right side is also slightly produced, 

 and bears three small hairs ; the outer branch of the left foot is twice as long as the 

 inner, and is unarmed except with one or two minute apical setse ; on the right side the 

 two joints of the outer branch form a powerfully prehensile but blunt, clumsily shaped 

 claw; the inner branch short, with an ovate terminal joint which bears four setse at its 

 apex. The first and fourth segments of the female abdomen (fig. 1) are much longer 

 and broader than the two intermediate segments, caudal stylets long, at least four times 

 as long as broad, each bearing a single marginal seta of moderate length, and four 

 terminal setse, one of which is about as long as the body of the animal. Abdomen of 

 the male (fig. 10) five-jointed. 



Habitat. — Off Port Jackson, Australia; off Kandavu, Fiji; lat. 30° 44' S., long. 44° 17' 

 W. ; North Atlantic in several stations from lat. 7° 33' N.,long. 15° 16' W., to lat. 

 26° 21' N., long. 33° 37' W. (Stations 350-353); in lat. 47° 25' S., long. 130° 32' E. 

 (Station 159); and lat. 40° 3' S., long. 132° 58' W. (Station 288). 



Very few specimens of Leuckartia were detected, and those mostly in imperfect 

 preservation. On this account I have been unable to figure or describe the species as 

 fully or minutely as I should have wished. I do not, however, find any noteworthy 

 difference between the Challenger specimens and those described by Dr. Claus, except the 

 size. Claus says "If — 2 mm. long." The measurement of my figured specimen is over 

 6 mm., and I am not aware that it was larger than the very few others which came under 

 my notice. 



2. Leuckartia (?) scopularis, n. sp. (PI. XIV. figs. 1-5). 



This species I know only from two or three imperfect specimens which were found 

 amongst surface animals taken between Japan and Honolulu. The peculiar brush-like 

 cushion of hairs attached to the inner side of the bases of the fifth pair of feet of the male, 

 afford what appears to be a sufficient specific character (figs. 3, 4), and though the foot 

 of the left side was imperfect in the only male specimen, that of the right side certainly does 

 not agree with Leuckartia Jlavicornis. The anterior antennae are twenty-five-jointed, and 

 that of the left side is simply geniculated (fig. 2) ; the caudal stylets (fig. 5) long and 

 unequal, the tail setse shorter than the abdomen, and nearly equal, except that one on each 

 side is about half as long again as the rest. The animal itself was not measured, nor
