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 riiore 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 {yoo) ^^ 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.
