a future paper; it is sufficient here to state that 
we recognize the Indo-Pacific species as A .

description: 5 Specimen described with an- 
terior body displaced from under carapace. 
Rostrum triangular, short, not reaching to 
middle of first antennular article, lateral margins 
slightly concave with curve continuous with 
orbito-rostral front; in lateral view, tip some- 
what depressed (that of female shown in draw- 
ing is crushed downward). Orbito-rostral 
grooves shallow and broad, interorbital crest 
slight and rounded, merging with the carapace 
near posterior margin of eyes. Orbital hood 
slightly inflated, hemispherical, frontal margin 
only slightly arcuate. 
Second antennular article slightly longer than 
broad, longer than the third article, shorter than 
visible portion of first article (some of the 
length visible of first article may be from dis- 
placement of body). Stylocerites short, acute, 
slightly exceeding end of first article. Basicerite 
with strong lateral tooth, slightly shorter than 
stylocerite. Lateral margin of schaphocerite al- 
most straight; lateral spines slightly exceeding 
length of antennular peduncle. Carpocerite ex- 
ceeding length of antennular peduncle by length 
of last article. 
Third maxilliped with first and last article 
equal in length, about twice length of middle 
article; tip of third article abruptly truncate and 
bearing numerous heavy setae, some of which 
equal article in length. 
Large cheliped with merus twice as long as 
broad, bearing two weak spines and a seta on 
inferior internal margin; superior margin 
rounded distally, inferior internal margin term- 
inated by small tooth. Chela almost three times 
as long as broad, with outer palmar face bearing 
triangular depressed area arising from transverse 
groove and continuing proximally to linea im- 
pressa; lower shoulders pronounced, but not 
continuing more than one-fifth width of face. 
Inner face of palm without marked depressions. 
Dactylus heavy, one third length of entire chela, 
tip rounded. 
Small cheliped with merus similar to that of 
large chela in armature, but with face 2.5 times 
as long as broad. Palm without sculpturing, 1.7 
5 This description and these figures were to be of 
specimens to be designated as neotype and neoallotype; 
however, the specimens were lost in the Hawaii Marine 
Laboratory fire.
