This small ? (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.
