NYMPHONIDAE 69 



Remarks. This species is much less setose than is typical of the short-necked, com- 

 pactly built forms, there being no long setae on the body and very few on the legs. The 

 chela differs from that of all the allied forms ; it recalls that of A'', proceroides, Bouvier 

 (cf. Figs. 29 d and 9), but the fingers are much curved and the spinules are longer and 

 fewer in number. 



A^. ueumoyri is most closely allied to A^. articulare, Hodgson, which also has the femur 

 in the female much enlarged throughout part of its length (Fig. 29 a). But it may be 

 readily distinguished from the latter by (i) its larger size and more compact build, 

 (2) the widely gaping fingers of the chela each armed with 6-9 instead of 18-25 spinules, 

 and (3) the marked difference in the outline of the femur in the male (cf. Fig. 29 b and c).
