REPORT ON THE BRACHYURA.

antennal joint, which scarcely attains or does not attain the front. The exterior 
maxillipedes cover the buccal cavity, and the merus of the endognath, as usual in this 
family, is triangulate and acute ; the exognath is rather broad, about as broad as the 
endognath, and its exterior margin is slightly arcuated. The chelipedes (in the adult 
males) are subequal, and sometimes considerably elongated ; the merus subcylindrical, 
and sometimes exceeding the carapace in length ; palm subcylindrical or compressed, not 
dilated ; fingers rather robust, compressed, and distally acute ; the ambulatory legs are 
relatively small, with the dactyli styliform. 
The species are found in the Indo-Malaysian, Japanese and Australian Seas, in 
littoral or shallow water ; one species at least ( Myra fugcix ) occurs commonly throughout 
the Indo-Pacific region. 
Besides the different forms regarded as synonyms of Myra fugax and Myra australis, 
Haswell, and Myra darnleyensis, Haswell, referred to below, I am not aware that any 
recent species have been described since the publication of Professor Bell’s Monograph. 
Myra fugax (Fabricius).

male, and an adult and two younger females; also in '49 fathoms (Station 190), in lat. 
8° 56' 0" S., long. 136° 5' 0" E., a young male. 
1 The genus Myrodes, Bell, which is united by Haswell in his Catalogue of the Australian Crustacea, 1882, with 
Myra should, I think, be retained as distinct.
