PACIFIC SCIENCE, Vol. VII, October, 1953 
The type specimen was collected by Bige- 
low at Bimini Harbor, Bahamas. Edmondson 
(1921) reported that a female specimen was 
taken on Waikiki Reef, Oahu, Unfortunately, 
I have not been able to locate this specimen 
in the Bishop Museum for comparison with 
the specimen taken at Kawaihae. Edmondson 
states that the specimen which he collected 
agreed with Bigelow’s previous description 
for the species. The Kawaihae specimen agrees 
with Bigelow’s description in color, shape of 
the eyes, general body proportions, shape of 
the lateral margin of the fifth thoracic somite, 
shape of the telson, and the presence of two 
lobes between the inner and outer spines of 
the uropods. However, there are certain char- 
acteristics in which the specimens differ con- 
siderably. Bigelow’s type possesses definite 
longitudinal carinae on the carapace, the ros- 
trum is truncate, the anterolateral angles of 
the carapace are rounded and armed with a 
short spine, and the outer margin of the uro- 
pods is armed with six movable spines. The 
Kawaihae specimen, on the other hand, does 
not have any carinae on the carapace, the 
rostrum is distinctly triangular, the antero- 
lateral angles of the carapace are rounded and 
unarmed, and the outer margin of the uropods 
is armed with only five movable spines. I 
believe that these differences are due to the rel- 
atively immature condition of the Kawaihae 
specimen, and that it is probably the last 
postlarval stage of this species. It is possible 
that the subsequent molt would reconcile the 
differences between this and the Bimini spec- 
imen. 
Bigelow makes little note of the submedian 
spines on the posterior margin of the telson. 
His figure (1894: pi. 22) is indistinct, but 
there appears to be a line indicating that they 
possess movable tips. In the Kawaihae spec- 
imen the tips of these spines are unquestion- 
ably movable. 
No male specimens have been reported. 
The largest of Bigelow’s specimens was 41 
mm., Edmondson’s was 47 mm., and the Ka- 
waihae specimen is considerably smaller, be- 
ing only 20 mm. in length. 
DISTRIBUTION: The type specimen was col- 
lected in calcareous sand at Bimini Harbor, 
Bahamas. In the Hawaiian Islands one spec- 
imen was taken from dead coral on Waikiki 
Reef, Oahu, and another at Kawaihae, Hawaii, 
at a night light. These are the only records 
known for this species.

DESCRIPTION: Carapace, excluding rostrum, jl 
about as long as greatest breadth; slightly 
narrower anteriorly than posteriorly; distinct j; 
gastric grooves and cervical groove; median, ij 
intermeiate, lateral, and marginal longitu- |! 
dinal carinae present, median discontinuous 
and bifurcated anterior to cervical groove, || 
lateral posteriorly reflexed toward gastric jl 
groove; anterolateral and posterolateral angles i 
unarmed and rounded. Rostrum broader than j 
long, truncate, small median carina, lateral j!: 
margins upturned and rounded anteriorly. I 
Ophthalmic somite exposed, anterior margin 
concave between base of eyestalks. Eyes large; 
cornea set transversely on stalks, only slightly 
broader than greatest breadth of stalk, about 
0.25 total length of carapace, including ros- 
trum. Antennular peduncle about same length 
as carapace, excluding rostrum. Ischio-meral 
articulation of raptorial claw terminal; ventral 
surface of merus longitudinally grooved 
throughout its length for reception of pro- 
podus; carpus with median and lateral carinae; 
propodus finely pectinate along outer surface, 
three movable spines near proximal end; dac- 
tylus not inflated at base, outer margin slight- 
ly concave, armed with six teeth. Anterior 
margin of propodus of third, fourth, and 
fifth thoracic appendages straight (Fig. 9c-e), 
posterior margins rounded; propodus of first 
thoracic appendage nearly circular (Fig. ^d). 
Mandibular palp composed of two segments. 
Fifth through eighth thoracic somites ex- 
posed, with longitudinal carinae; lateral mar-
