3° The terminal segment of the abdomen of the c? is indeed rounded (de Man), not truncate 

 (DE Haan, pi. 29). 



4° The fingers of the cheliped are in both sexes somewhat shorter than the palm (de Man), 

 hut not half the length of the latter (de Haan, 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 

 laro-e 9 (breadth of carapace about 1 7 mm.) 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 carapace 13.5 mm.) they are 2 l J. 2 times this breadth and more slender, which 



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

 penultimate pair (first and second pair wanting) is 3 times the breadth and 4 1 /;, 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 9i but de Man found legs with this "male" character in a young 9- an ^, as 

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

 dependent of age. 



6 n 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.

This genus was regarded by 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 Elamenopsis with its short legs doubtless resembles that of 

 Pinnoteres. Only one species is knovvn.
