stouter than rest of leg, and fingers one-fourth the length of the hand. 

 Second pair filiform, carpus ten-jointed, joints subequal. 



In a specimen from the Paumotus, agreeing with this species in 

 the teeth of the beak, and in its slender anterior feet, the general 

 colour consists of areolets of a slate shade, bordered by a bright green, 

 with a few small concentric circles of alternate slate and green. Only 

 an imperfect figure was made when the specimen was collected, and 

 in it the beak is not as much reflexed as in the gibbosus; yet as we 

 have not the specimen to refer to, we cannot say that the species is 

 different.

Length of body, one and one-fourth to one and a half inches. Of 

 the spines of the beak two belong to the beak proper and two are on 

 the cephalo thorax. Below the eyes on anterior margin two spines, 

 the lower quite small. Base of inner antennas with a longish spine
