Pilumnoplax cooki, sp. nov. 
(PL vii, fig. 3.) 
Carapace more convex than usual in the genus, especially fore and aft, about f as long as broad, 
naked, sparingly and irregularly punctate, regions faintly indicated. 
Front horizontal, advanced, slightly concave or emarginate; transversely sulcate above the margin, 
sulcus widest at the middle and tapering to each end; slightly more than a third the greatest breadth 
of the carapace. 
Antero-lateral borders not more than one-half length of postero-lateral, cut into three projec- 
tions, the first a shallow lobe confluent with the outer orbital tooth, the second a blunt obtuse-angled 
tooth; edges of teeth sharp. The third prominence is a sharp ascending conical spine directed upward 
and forward, and situated considerably above. -the level of the teeth. 
Eye of good size, nearly filling the orbit; cornea brown in alcohol. Upper margin minutely 
notched near the middle, lower margin slightly emarginate below outer angle; inner angle a narrow 
tooth whose tip is just visible in dorsal view. 
The last joint of the peduncle of the antenna attains the edge of the front; flagellum twice as long 
as the orbit is wide. 
Chelipeds in male slightly unequal, heavy, a little more than twice as long as carapace; surface 
sparingly punctate; arm microscopically granulous, especially toward the margin; a small superior 
subterminal tooth; wrist less evidently granulous, inner lobe truncate, its distal corner in form of a 
blunt tooth; hands almost smooth, fingers gaping, the pollex curved downward in its basal half; dark 
color only on distal two-thirds, the color darkest in the middle, and a brown horn-color at each end. 
Legs very slender, long, second pair longest, 2J times as long as the carapace; smooth, unarmed, 
nearly bare. 
Length of type male 12.7, width 15 mm. 
The character of the antero-lateral dentation, as well as the convexity of the carapace, distin- 
guishes this species from all others. 
Named for Captain Cook, who discovered the Hawaiian Islands. 
Distribution . — South coast of Oahu, 293 to 330 fathoms, stations 3818, 3917; Pailolo Channel, 256 to 
290 fathoms, stations 3865, 3866 (type locality), 3883, 3884; northeast approach to Pailolo Channel, 
272 to 304 fathoms, stations 4089, 4096; vicinity of Kauai Island, 283 to 309 fathoms, station 4130. 
Cat. No. of type, 29364. « 
Family PALICID^. 
Palicus fisher i, sp. nov 
(PI. vii) fig. 5.) 
Carapace with regions well marked, covered with minute granules, from each of which a short 
curved hair arises and with tubercles symmetrically arranged on the summits of the areolse and 
coarsely granulate, the chief tubercles disposed as follows: A transverse curved line of about fourteen 
running from the penult lateral tooth across the cardiac region; three mesogastric; four protogastric, 
in one line; two epigastric; a cluster of three anterior branchial; smaller tubercles in a line of five or six, 
and one median in advance of the line on the intestinal region, and three on the posterior part of each 
branchial region. 
Front cut into four narrow lobes, tips upturned, middle pair much lower, longer, more acute, and 
more depressed than outer pair and separated from each other by a deep U sinus. 
Lateral borders moderately diverging posteriorly, cut into five long acute teeth, including orbital, 
diminishing backward, the last much the smallest. Posterior margin cut into nine to eleven small 
lobes not contiguous. 
Inner supraorbital lobe separated by broad deep sinus from front, its inner angle very prominent 
and elevated; three deep sinuses in upper margin of orbit; a small V sinus below outer tooth; inner 
suborbital tooth narrow, acuminate. Eyestalks sharply granular and nodular.
