BRACHYURA AND MACRURA OF HAWAIIAN ISLANDS. 
857 
Two triangular notches in the upper margin of the orbit and a larger one below the outer angle; 
inner suborbital tooth broad and blunt, less prominent than upper angle. 
Of the five normal antero-lateral teeth, the orbital is small and inconspicuous, the second is repre- 
sented only by a granule which projects sharply 
beyond the other marginal granules; third and 
fourth teeth of good size, with a sharp point turned 
forward; fifth tooth very small, indicated rather by 
the notch and groove in front of it. 
Chelipeds very unequal in both sexes, arm short, 
granulous outside, upper border spinulous; wrist and 
outer surface of smaller palm, upper half of larger 
palm coarsely granulous; inner tooth of wrist tri- 
angular, sharp; behind and below it a much smaller 
tooth; the infero-distal half of the larger palm, 
though smooth to the naked eye, covered with very 
minute reticulating granules. Fingers of larger chela 
gaping moderately, a large tooth at base of dactyl. 
Legs long and slender, moderately hairy; me- 
ropodites armed above with short spinules or sharp 
granules which are also found on the ridges of the 
two following joints. 
Dimensions. — Male (station 4066), length 5.4, width 8 mm 
width 8.5 mm. 
Distribution. — Vicinity of Laysan Island, 57 to 163 fathoms, stations 3935, 3936, 3939; Aleunihana 
channel, 176 to 49 fathoms, station 4066 (type locality). Cat. No. of type, 29529. 
This species approaches nearest M. truncalifrons Rathbun of the West Indies, but the latter is 
more coarsely granulated, less distinctly areolated posteriorly and the front less evidently six-lobed.

Honolulu; Waikiki Beach; south coast of Molokai, 23 to 73 fathoms, stations 3847 to 3849; Auau

Penguin Bank, 28 to 14 fathoms, station 4034; northeast coast of Hawaii, 24 to 83 fathoms, station 4061 ; 
vicinity of Kauai, 68 to 179 fathoms, station 4128; vicinity of Modu Manu, 24 to 40 fathoms, station 4163. 
Hawaiian Islands (Dana). 
The line is not sharply drawn between this species and the preceding. Judging from specimens 
which have been preserved an equal length of time in alcohol, C. Isevissima has an orange-reddish 
color, while C. niger is brownish. Adult C. niger has the carapace finely granulate under the lens. 
Adult C. Isevissima has the central part of the dorsum smooth; young specimens of both are much 
smoother. Neither is the arching of the fingers, mentioned by Dana and Alcock, to be relied on. 
Phymodius ungulatus (Milne Edwards).

Honolulu; reef in front of Honolulu.

While this species, so far as I have examined specimens, appears to be distinct from P. obscurus, 
yet the chelipeds are not just as described by Alcock, being smoother than in P. obscurus. See
