HaLE—AUSTRALIAN CUMACEA 179 
First antenna almost as long overall as second; with third joint of pedunele 
barely shorter than second, and with first about as long as second and third to- 
evether ; first joint of main flagellum stout, wtih a dense brush of sensory filaments, 
which conceal at least a second joint. 
Second antenna with flagellum stout, curved, subequal in length to last pe- 
duneular joint; five-jointed and apparently with a small terminal jointlet eon- 
cealed by a dense series of setae emanating from the fifth joint. 
The maxillae and first and second maxillipeds are as in Cumella. The last 
joint of the first maxilliped is elongate, more than two-thirds as long as the penul- 
timate joint.

somites (XX 112). 
Third maxilliped (as in female) scarcely differing from first peraeopod ; its 
basis is a little shorter, but the rest of limb is equal in length to that of first leg, 
although stouter: earpus longer than merus or propodus, which are subequal in 
length; exopod stout. 
First peraeopod short, its total length barely equal to that of carapace ; basis 
almost as long as remaining joints together ; carpus as long as ischium and merus 
together, the latter longer than propodus. 
Second peraeopod with basis shorter than vest of limb, merus a little longer 
than carpus, and dactylns more than twice as long as propodus; (while the ischium 
is distinct in the female, I cannot distinguish it in the fully adult male). 
Exopod of third peraeopod weil-developed, with robust flagellum; basis in 
third and fourth peraeopods almost half as wide as long, and about equal in length
