Funafuti, Ellice Ids.; reef; Dee. 24, 1899 ; 1 ? juv. 



This small 9 (5.2 x 8.7 mm.) is not typical, the hands are narrower than 

 all other, but larger, specimens examined, the immovable finger is more 

 elongate, and the palm is not cristate beneath. In other respects the crab 

 might easily be a dodone ; the outline and proportion of the carapace are 

 normal, the central portion is very smooth, there are short ridges on the 

 side-teeth T and S (of Dana) and on the hepatic region and just inside 

 of T.
