3" The terminal segment of the abdomen of the cf is indeed rounded (de Man), not truncate 

 (df. Haan, 1)1. 29). 



4" The fin,^ers of the cheliped are in both sexes somewhat shorter than the palm (de Man), 

 but not half the length of the latter (de Haax, pi. 29). They are spooned at the tip. 



5" In the length of the walking legs there is much variation between the specimens: in one 

 large 9 (breadth of carapace about 1 7 nmi.) the walking legs of the first and second pair 

 are only twice the breadth of the carapace, and the legs are rather robust; in another 9 

 (breadth of carapace 13.5 mm.) they are 2Y3 times this breadth and more slender, which 

 agrees with de Haan's figure (pi. 29). In a small cT (breadth of carapace 9 mm.) the 

 penultimate pair (first and second pair wanting) is 3 times the breadth and 4^^ times the 

 length of the carapace (including rostrum) ; the last legs are only slightly shorter. Judging 

 from this we should conclude, that in the d" the legs are relatively longer and more slender 

 than in the Q, but de Man found leg^s with this "male" character in a young 9, and, as 

 this author presumes, it is perhaps better to regard this relative length of the legs as 

 dependent of age. 



6" As DE Haan (pi. 29) and Alcock stated, the meropodites of the legs end at the upper border 

 in a small prominence. In de Man's specimen this prominence is very large, about half as 

 long as the next carpopodite. This character may suggest, that de Man's specimen is 

 indeed a subspecies, but we cannot regard it as such, as long as only one single specimen 

 is available. 



The chief habitat of the species seems to be Japan, but it has also been found at the 



Andamans, in the Gulf of Martaban, at Singapore and Ternate.

'I his genus was regarded b) Milne-Edwards as a transition between Pinnotercs and 

 Elamena and, though we know that the Hymenosomidae have nothing to do with the Pinno- 

 teridae, the general appearance of E/aiimiopsis with its short legs doubtless resembles that of 

 Pinnoteres. Only one species is known.
