Hanauma Bay, Black Point, Waikiki, Nana- 
kuli, Mokuleia, Kaaawa, and Kawela Bay; on 
Maui, Makena, Kalama Park, Lahaina, and 
12 miles south of Lahaina. The ” Albatross” 
collected five specimens from "Honolulu 
Reef” (U.S.N.M. 63552, 63553). There is only 
one dredged specimen, taken between 40 and 
350 feet deep off the southwest coast of Oahu. 
Edmondson (1925) has reported the species 
(as C. insignis) from Laysan and Lisianski Is- 
lands and Pearl and Hermes Reef. 
As C. insignis the species has been reported 
throughout the tropical Indo-Pacific region 
from the Red Sea to Samoa; Edmondson 
(1925) has reported it from Johnston Island 
in the central Pacific.

TYPE SPECIMEN: A female 15.6 mm. long, 
collected at Kalama Park, southeast Maalaea 
Bay, Maui; it was collected from old coral at 
a depth of about 8 feet. Five paratypes, one 
from shallow water at Makena, Maui, one 
from shallow water at Waikiki, Oahu, and 
three from about 18 feet of water off Waikiki 
Reef, Oahu (U.S.N.M. 93513). 
DESCRIPTION: Rostrum acute, twice as long 
as broad at anterior margin of base, tip reach- 
ing to end of first antennular article. Rostral 
Carina well- developed crest continuing to mid- 
dle of orbital hoods, then broadening into 
dorsally flattened triangular area. Orbital 
hoods inflated, rounded anteriorly, well de- 
marked from surrounding carapace, except on 
posterior margins merging with carapace; or- 
bital hoods very clear. Area between orbital 
hoods and rostrum flattened; anterior margin 
arcuate. Anterior portion of carapace de- 
pressed, seen in profile, with small medial 
protuberance or lobe. 
Second and third articles of antennular pe- 
duncle equal in length but both slightly 
shorter than visible portion of first article; sec- 
ond article about 1.3 times as long as broad. 
Stylocerite well developed, tip reaching be- 
yond end of first antennular article. 
Lateral spine of basicerite well developed 
but not reaching end of first antennular arti- 
cle. Scaphocerite with lateral spine dominant 
and squamous portion reduced; lateral mar- 
gin strongly concave. Carpocerite as long as 
antennular peduncle; both exceeded by sca- 
phocerite. 
Large chela subcylindrical, 1.3 times as 
broad as high, 2.7 times as long as broad 
[note: Figs. 44<; and 44^ show neither maxi- 
mal nor minimal diameters] ; margins rounded; 
tapering toward fingers. Palm marked by deep 
transverse groove proximal to articulation of 
finger, which spreads and soon disappears on 
superior face, but on inferior face continues 
into shallow, poorly defined depressed area 
extending distally to articulation of dactylus 
and proximally an equal distance. Adhesive 
plaque on independent lobe, demarked by 
palmar depression on inferior side and by 
deep, short depression on superior side that 
accommodates ridge of dactylus upon flexure. 
Dactylus about 0.3 length of entire chela; 
high, narrow, arcuate, with pronounced ridge 
along free margin; tip rounded. Fixed finger 
blunt at tip. Chela with occasional setae and 
usual tufts on fingers. Merus triangular, sharp- 
ly angled; superior margin terminating as 
acute dentate projection, with 5 small inden- 
tations proximally from which very small 
bristles arise; inferior external margin with 7 
similar indentations; inferior internal margin 
with 9 indentations and strong subacute tooth 
subterminally. Ischium with 3 indentations 
for bristles. 
Small chela cylindrical, 5 times as long as 
broad, fingers about 0.7 as long as palm. Fin- 
gers narrow. Chela with usual setae. Carpus of 
usual form. Merus about 0.7 as long as chela, 
triangular, with indentations similar to merus 
of large chela but fewer; inferior internal mar- 
gin unarmed. 
Carpal articles of second legs with ratio 
10 : 11 : 4 : 5 : 7. 
Ischium of third legs with movable spine 
on inferior margin (difficult to see) . Merus 5 
times as long as broad, with strong, acute
