Carapace moderately elongate, not depressed, the gastric and cardiac 

 regions very strongly calcified, otherwise soft ; rostrum prominent (beak-like 

 in the only species known). 



The abdomen, except for the first two terga which are partly calcified 

 and for the last tergum and telson which are properly calcified, is a soft bag, 

 flexed but not spirally coiled, perfectly symmetrical in the male, but rendered 

 unsymmetrical in the female by the presence of a large fleshy brood-pouch 

 on one side only. 



Eyestalks stout, ophthalmic scales widely separated, spiniform. Anten- 

 nal acicle large, antennal flagellum long, non-setose. 



The endopodite (palp) of the ist pair of maxillae is furnished with a 

 recurved flagellum. The exopodites of all three pairs of maxillipeds have a 

 well developed flagellum : the external maxillipeds are approximated at base. 



The chelipeds are in all respects equal and similar, massive in both sexes, 

 but more so in the male : the fingers, which end in corneous tips, open in a 

 nearly horizontal plane. 



The crawling-legs (2nd and 3rd pairs) are long and stout, particularly 

 as to the dactyli. The 4th pair of legs end in particularly perfect chels, 

 the 5th pair are also chelate : there is an inconspicuous patch of small 

 corneous granules near the tip of the 5th pair of legs, but none at all on the 

 chete of the 4th pair. 



In the male the first two abdommal somites carry each a pair of unira- 

 mous appendages modified for sexual purposes ; and the 3rd, 4th and 5th 

 somites carry on one side on\y—rioht or left—t3.c\\ a minute biramous appen- 

 dage with the endopodite quite rudimentary.
