124 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
triangular and subacute, as represented by de Man ;! the outer margin of the 
beveled edge is more or less spatuliform. The granular line defining the 
lateral margin may be present for two-thirds the length of the margin or may 
be evident only near the antero-lateral angle, without regard to sex. In all 
the specimens I have examined (27 from 9 localities), the granules of the 
carpus of the large claw, though small, are visible to the naked eye. The 
inner surface of the palm is more or less coarsely granulate ; the immobile 
finger more or less strongly curved. 
The color of the Maldive examples in alcohol is dark green or blue, with 
patches of yellow speckled with mulberry at the antero-lateral angles ; large 
cheliped yellow with large brick-red patch at base of pollex ; smaller cheliped 
and legs light mulberry.

and synonymy. 
Gan Island, Addu Atoll, at anchorage, 20 fathoms, January 6; one female, 
13.5 mm. wide, and 9.1 mm. long, in which the eyes project beyond the cara- 
pace for more than half (;5';) of their length.

Figs. 3-5. 
The length of the carapace is nearly two-thirds of its greatest width. The 
lateral margins are provided with a strong acute tooth at their anterior fourth, 
which projects outwardly beyond the antero-lateral angle. 
Front wider than orbit, margin sinuous, with a shallow median tooth and a 
notch at the outer angle in which the antenna is lodged ; an impressed line 
just above the margin. 
The supra-orbital margin is sinuous and slopes backward and outward ; its 
outer angle is blunt. 
The posterior width of the carapace is nearly three-fourths of the fronto- 
orbital width. 
The surface is punctate under the lens, and closely covered with finer 
wrinkles. The H-shaped depression in the centre is very shallow. 
The eyes almost attain the outer angle of the orbit, the cornea is light- 
colored in alcohol, and on the under side extends one-half the length of the 
stalk. 
The lower margin of the orbit has a shallow lobe near its middle. 
The antero-external angle of the merus of the outer maxillipeds is produced, 
the anterior margin is excavate.
