Kubo reported that in his female specimen, 
somewhat larger than this, the chelae were no- 
ticeably asymmetrical; in this specimen the 
chelae were almost the same size. 
DISTRIBUTION: Kubo’s specimens came from 
Kusaie in the Caroline Islands while our speci- 
men came from Eniwetok and was found under 
a boulder in the sand on the lagoon side of an 
islet.

TYPE SPECIMEN: An ovigerous female, cara- 
pace length of 3.9 mm., total length of 11 mm., 
collected from coralline ridge, ocean (windward) 
reef, Parry Island, Eniwetok, 3 March 1957, by 
A. H. Banner (station BE-23). Sole specimen 
known. 
DESCRIPTION : Body form usual. Rostrum 
short, reaching about to end of first antennular 
article; acute in dorsal view, triangular with 
straight sides; in lateral view with dorsal margin 
curved upward towards tip, ventral margin with 
double curve and bearing small tuft of setae; 
rostrum and carapace without carina. Supra- 
corneal teeth distinct, acute, reaching almost to 
end of cornea; extracorneal teeth larger, exceed- 
ing length of cornea; infracorneal projection 
absent. Corneas covered posteriorly by collar 
between supra- and extracorneal teeth. Ptery- 
gostomial corner projecting but rounded. 
Antennular peduncle short and heavy, with 
second article almost twice as long as broad. 
Superior distal margins of first and second ar- 
ticles each armed with four strong teeth. Stylo- 
cerite narrow, with tip reaching to near end of 
second article. Upper flagellum with only trace 
of bifurcation. Antennal peduncle also heavy. 
Basicerite thick, lateral region projecting as a 
broad tooth, bearing broadly acute tip. Carpo- 
cerite very heavy, only 1.5 times as long as broad, 
and 1.3 times broader than thick; tip reaching 
beyond end of antennular peduncle. Scapho- 
cerite with tip of lateral spine reaching slightly 
beyond end of antennular peduncle, squamous 
portion broad and rounded, almost as long as 
lateral spine. Antennal flagellum reaching pos- 
teriorly to end of second abdominal segment. 
Mouth parts protruding as those in A. para- 
gracilis Coutiere and A. huikau Banner with in- 
flated labrum and with psalistome of mandibles 
expanded and almost hemispherical; teeth on 
psalistome small and numerous. 
Chelipeds symmetrical except for 10 per cent 
difference in size. Ischium heavy, 0.7 length of 
merus, bearing five to six movable spines on 
inferior, three on superior margin. Merus com- 
pressed, triangular in section, with inferior sur- 
face flat and less broad than sides; outer face 
1.5 times as long as broad at maximum breadth. 
Carpus 0.8 as long as merus, proximally very 
thin and narrow, distally greatly expanded to be 
0.5 as broad as long; triangular in section; distal 
margins slightly projecting to cover base of 
chela. Chela short, 1.8 times length of merus, 
flattened, with thickness 0.5 of maximum 
breadth; inner face flattened, outer face convex; 
suboval area of outer face running from base to 
articulation of flattened dactylus; area distally 
delimited on inferior side by rounded shoul- 
der; triangular area of lower distal margin of 
palm and proximal portion of finger armed by 
strongly projecting papillae, those best devel- 
oped longer than broad at base and turned dis- 
tally; setae arising between bases of papillae; 
inner face without papillae. Dactylus 0.4 as long 
as palm, curved, crossing tips with fixed finger, 
armed with two low rounded teeth fitting ex- 
actly with cutting edge of fixed finger. 
Second legs markedly shorter than third legs, 
with length from meral-carpal articulation equal 
to combined lengths of ischium and merus. First 
and fifth carpal articles subequal; second, third, 
fourth articles subequal, each about 0.4 length 
of first or fifth article; first carpal article prox- 
imally narrow, about half width of fifth article. 
Third legs robust. Ischium unarmed, 0.5 
length of merus. Merus unarmed, 0.4 as broad 
as long. Carpus armed distally on superior mar- 
gin with rounded tooth, on inferior margin with 
subterminal movable spine; almost 0.6 as long 
as merus, slightly more than half as broad as 
merus. Propodus at most slightly longer than 
merus, slightly curved, with five inferior and 
one distal spines; spines leaving middle portion 
of propodus unarmed. Dactylus curved, acute, 
simple, bearing tuft of setae. Fourth legs similar 
but with spines of propodus more continuous 
in arrangement. Fifth legs with only three in- 
ferior spines on propodus; "brush” feebly de-
