BULLETIN OE THE UNITED STATES FISH COMMISSION. 
Chelipeds shorter than carapace, unequal in both sexes, only the right or larger one being stouter 
than the first pair of legs; the upper surface bears some flat lobules and sharp granules; larger palm 
only a little longer than high. 
First pair of legs a little longer than carapace; merus sharply granular, anterior border with four 
or five small spines and ending in a large sharp-pointed tooth, posterior border denticulate; anterior 
edge of carpus with a lobe near either end, posterior edge terminating in a small spine; posterior 
border of last two joints serrulate. 
Second and third pairs of legs about If times as long as carapace; merus broadened in middle, 
with sharp granules or spinules arranged in rows, anterior border with three or more spines increasing 
distally, a terminal triangular subacute tooth, posterior edge with seven or more spinules, including 
one terminal; last two joints much widened, anterior border fringed with long 
hair, posterior border of propodus four to five, of dactylus two to three — serrate. 
Last pair filiform, much shorter than carapace, sharply granular or spinu- 
lous up to the dactylus, which is subequal to the propodus. 
First segment of abdomen in both sexes carinate, carina granulate and 
ending in a sharp upturned spine; adjoining segment of sternum armed with a 
similar spine, which lies just, outside the other. 
Dimensions . — Male type, length 12, width 14.1 mm. The species grows 
much larger, an immature female with soft shell, station 4066, measuring 22.6 mm. long and 26.5 wide. 
Color . — Legs with broad transverse bands of color. 
Distribution . — South coast of Molokai Island, 23 to 73 fathoms, stations 3846, 3847, and 3848; 
vicinity of Laysan Island, 16 to 163 fathoms, stations 3j)39 and 3962; vicinity of Kauai Island, 40 to 
233 fathoms, stations 3982 and 3987 (type locality); Aleunihana Channel, 49 to 176 fathoms, station 
4066; north coast of Maui Island, 99 to 106 fathoms, station 4077. Cat. No. of type, 29368. 
Named for Mr. Walter K. Fisher, of Stanford University, who accompanied the Fish Commission 
party to the Hawaiian Islands in 1901. 
This species is allied to P. serripes (Alcock & Anderson) and P. investigatoris Alcock; differs from 
the former in having the borders of the carapace more deeply incised and its surface more tubercu- 
late; in P. investigatoris the surface is marked by tubercles on the areolae, but is not granulate, and 
the teeth of front and posterior margin are more acute.

Palicus oahuensis, sp. nov. 
(PI. vn, fig. 4.) 
Carapace quite high in the middle, covered with distant tubercles and granules, between which 
the surface is microscopically granulate. 
Median lobes of front small, round, near together, on a lower level than outer pair, which are 
broad and very shallow, and separated feebly from the inconspicuous inner supraorbital lobe. Three 
small notches in upper margin of orbit; outer tooth long, triangular, acute. 
Antero-lateral margins forming a very obtuse angle to each other and armed with four teeth besides 
the orbital; first distant from orbit and lobiform; second and third much larger, subequal, dentiform; 
last very small, acute. Postero-lateral and posterior margins with a few spaced tubercles. 
Chelipeds about as long as carapace (in female) unequal, larger pair not much stouter than first 
leg; surface granular; larger palm about 1} times as long as wide, fingers nearly 
as long as palm and crossing each other at some distance from tip. 
First pair of legs a little longer than carapace, merus and carpus granulate, 
margins of former bluntly denticulate, a prominent blunt tooth at end of 
anterior margin; two lobes on same margin of carpus; edges of last two joints Fig . 2 —paUcus oahuen 
ent ^ re - sis, type female, larger 
Second and third pairs of legs about If times length of carapace, merus chela, x 4£. 
ovate, granular, margins irregularly dentate, teeth smaller and more numerous 
on posterior than on anterior border; the latter bearing a large terminal tooth, which is larger and 
acute on second pair, lobiform on third pair; remaining joints similar to those of first pair. 
Last pair filiform, granulate, not f as long as carapace. 
First four segments of female abdomen carinate, first three segments granulate, their carinse, 
though not prominent, visible from above.
