Crangon hawaiiensis Edmondson, Bernice P. 
Bishop Mus., Bui. 27: 14, figs. 2a-i, 1925. 
DESCRIPTION : Rostrum triangular with nar- 
row acute tip, about 1.5 times as long as broad 
at base, tip probably reaching to near end of 
first antennular article. Orbital hoods prob- 
ably subacute, pointed, and somewhat shorter 
than rostrum. Orbitorostral grooves shallow. 
First antennular article heavy, probably 
with visible portion slightly longer than sec- 
ond article. Second article about 1.3 times as 
broad as long, somewhat shorter than third 
article. Stylocerite reaching to or slightly be- 
yond end of first antennular article. Lateral 
spine of basicerite longer than stylocerite. 
Lateral margin of scaphocerite slightly con- 
cave; lateral spine 0.2 longer than squamous 
portion; tip reaching beyond end of anten- 
nular peduncle. Carpocerite heavy, reaching 
about to end of scaphocerite. 
Mouthparts similar to C. paragracilis and 
C nanus (see pp. 96 and 90). 
Large chela almost 2.5 times as long as 
broad, strongly compressed but not twisted, 
fingers occupying distal 0.3. Palmar surfaces 
smooth, rounded; slight concavity in inferior 
margin below and proximal to articulation of 
dactylus; faint groove on outer face of palm, 
extending short distance proximad from 
upper margin of dactylar articulation. Merus 
1.8 times as long as maximum breadth; in- 
ferior external margin rounded and not def- 
inite; superior margin terminating in acute 
tooth. Scattered setae on inner face of chela 
and on inferior internal margin of merus. 
Small chela lost. 
Carpal articles of second legs with ratio 
10 : 5 : 5 : 5 : 7; second article 1.1 times as 
broad as long. 
Ischium of third legs 0.5 length of merus, 
unarmed; merus 3.3 times as long as broad, 
with small acute tooth or smaller obtuse pro- 
jection; propodus 0.3 as long as merus, almost 
twice as wide distally as proximally, with 
neither inferior nor superior margins project- 
ing but terminating at approximately right 
angles without spines or teeth; propodus 0.9 
length of merus, curved, with 6 small spines; 
dactylus biunguiculate, curved and heavy, less 
than 0.4 length of merus, 2.2 times as long as 
broad at base, with distal unguis longer but 
less broad at base than inferior unguis. 
Sole specimen known female 12 mm. long. 
DISCUSSION: The type specimen was re-ex- 
amined and redrawn for this study. Unfor-
