rangCj it was collected at Makena, Kalama 
Park, Lahaina, and four localities ranging 
from 12 miles south of Lahaina to 10 miles 
north of Lahaina. The only record of the spe- 
cies from deeper water was a collection from 
180 feet off Kaena Point, Oahu, where it was 
living in sponges. Edmondson (1925) has re- 
ported it from French Frigate Shoal, Pearl and 
Hermes Reef, Laysan, Lisianski and Ocean Is- 
lands. The "Albatross” took only one group 
of specimens, those from Laysan Island, evi- 
dently from shallow water. 
The species has been reported from Johns- 
ton and Wake Islands (Edmondson, 1925) 
and from Tahiti in the central Pacific, and 
from the Indian Ocean. It was not reported 
by de Man from the Siboga Expedition ma- 
terial, although the range of the species ex- 
tends to either side of the area investigated by 
that expedition.

description: Rostrum not reaching be- 
yond middle of visible portion of first anten- 
nular article, broad yet acute, with dorsal Ca- 
rina continuous from tip to behind orbital 
hoods. Orbital hoods with no trace of teeth, 
depressed anteriorly as flattened shelf expand- 
ing as broad area between base of rostrum and 
anterior portion of orbital hoods; frontal mar- 
gin of this area varying from arcuate to S- 
shaped. Margin of carapace above base of an- 
tenna higher than at base of the orbital hoods, 
forming slight but distinct depression. 
Antennular peduncle short, with second 
article somewhat longer than visible portion 
of first, about twice as long as third (note that 
the elongation of the second article shown in 
Figure 34^ is atypical) . Stylocerite short and 
variable with lateral spine not reaching end of 
first antennular article. Basicerite with acute 
lateral spine of varying size, usually quite 
small. Scaphocerite relatively narrow, with 
strong lateral spine 1.3 times as long as squa- 
mous portion; lateral margins concave. Lat- 
eral spine of scaphocerite usually longer than 
antennular peduncle, usually greatly exceeded 
by carpocerite. 
Large chela subcylindrical, tapering, with- 
out grooves or lobes; distal portion slightly 
bent, thus lower surface concave in profile. 
Fingers about 0.3 length of entire chela. Dac- 
tylus laterally disposed, with strongly arcuate 
margin. Distal portion of inner face of chela 
sometimes sparsely covered with setae. Carpus 
of usual form. Merus short, triangular, with 
superior margin ending distally as rounded to 
subacute projection, inferior internal margin 
with acute tooth distally. 
Small chela short, approximately 3 times as 
long as broad. Fingers 0.6 as long as palm, 
broad, flattened, lined with dense setae in 
male, narrower and conical in female. Palm 
somewhat triangular in section. Merus similar 
to that of large chela. 
Carpus of second legs variable, but usually 
with ratio 10 : 30 : 9 : 9 : H. 
Ischium of third legs with small blunt spine 
(not shown in Fig. 34/?). Merus about 3.5 
times as long as broad, with strong acute 
tooth on distal portion of inferior border. 
Carpus with 1-5 movable spines on inferior 
border, continued distally as acute tooth; su- 
perior margin with numerous long setae. Pro- 
podus with varying number, usually about 12, 
movable spines along inferior margin, most of 
them in pairs, with many long setae on su- 
perior margin. Dactylus short, 0.2 as long as 
propodus, with small secondary unguis ro- 
tated so as to be almost invisible, except when 
legs are turned slightly. Fifth legs with 
"brush” well developed.
