BRACHYURA AND MACRURA OF HAWAIIAN ISLANDS. 
899 
Antennular scale a little larger than antennal scale, one-fifth as long as carapace, acute, upper 
margin spinose for its distal three-fifths, a single spine at outer distal angle. Antennal scale acute, 
tipped with a spinule, and reaching to end of antennular peduncle. 
External maxilliped barely reaching end of antennular peduncle, and furnished with an epipod. 
First thoracic leg a little longer than body; arm and palm with a distal spine above, wrist with a 
distal spine below. Upper and lower margin of arm and upper margin of palm spinulous. Propodus 
longer than merus, carpus longer than manus, digits one-third again as long as palm. 
Second and fifth pairs of legs diminish in length and stoutness, the second pair more than one- 
third the length of the first pair; last pair imperfectly chelate in male. 
Dimensions. — Male, length of carapace 35, entire length of abdomen 46.5, length of first pair of 
legs 85.2. 
A single specimen only was taken at station 4151, vicinity of Modu Manu, 800 to 313 fathoms. 
(Cat. No. 30322. ) 
In shape the species resembles P. phosphorus ( Alcock), but is at once distinguished by the uniform 
roughness of the carapace, the absence of true spines from the dorsal surface of cara- 
pace and abdomen and by the finer and more numerous spinules of the margin. 
Named for Mr. J. 0. Snyder, who accompanied the Fish Commission party in 
1902.

In Hawaiian specimens the number of lateral spinesis8tol0-3(or4) -15 (14orl6). 
On the gastric region there are from 3 to 5 larger median spines behind the front, 
of which 1, 2^ or more may be double. 
Most of the specimens are small; the largest, a male, station 4111, measures 111.6 mm. long, length 
of carapace 50.8. 
Color. — “Light opaque madder pink.” 
Distribution. — Vicinity of Kauai Island, 385 to 550 fathoms, stations 3989, 4019, 4028, and 4138; 
north coast of Molokai Island, 552 to 809 fathoms, station 3887; between Honololu and Kauai Island, 
508 to 557 fathoms, station 4007; Kaiwi channel, 460 to 470 fathoms, station 4111. 
Polycheles asper, sp. nov. 
(PI. xxiv, fig. 11.) 
Carapace nearly as long as exposed part of abdomen; strongly convex from side to side and also fore 
and aft; oval; surface covered with spinules and short hairs. Frontal margin concave, armed with 
two spines at the middle, one at inner angle of orbit; outer margin of orbital notch bordered with 
spines which are continued along the frontal margin halfway to lateral margin. Orbital notch narrow 
U-shaped; a large outward-pointing spine at extremity of eye. Lateral margins armed with spinules 
which diminish posteriorly and become almost obliterated. They number 15-8 or 10-28 or 29. Median 
carina double, armed with spinules larger than those of the general surface, and larger in front of than 
behind the cervical suture. Similar ridges of spinules follow the cervical suture along its posterior 
branch to the lateral margin and part way along the anterior branch; the longitudinal ridge of the 
branchial region is similar in position to that of P. granulatus. Longitudinal ridges of side wall finely 
granulate or denticulate, continuous. 
Abdomen tuberculate; first to fifth terga bluntly carinate, as is also the anterior end of the sixth 
and seventh; the seventh carina only has a short backward-pointing spine. 
Antennular scale subacute, not reaching beyond penult segment of peduncle, inner margin spined, 
a row of spinules at distal outer angle. Antennal scale suboval, reaching to distal third of last segment 
of peduncle. 
The outer maxilliped readies to middle of antennal scale, and is provided with an epipod. 
First pair of thoracic legs missing; second pair two-thirds as long as carapace.
