HALE—AUSTRALIAN CUMACHA 177 
Basis of third maxilliped as long as rest of limb; ischium very short, propo- 
dus twice as long as dactylus, and half as long again as carpus which is subequal 
fo Merns; With exopod, 
Wivst peraeopod with basis only as long as isch, merns and earpus together ; 
the sarpus is lone, more than one-third longer thin propodus, longer than isehion 
and merns together and three times as long as dactylus. 
Basis of second peraeopod two-thirds as long as rest of limb and twice as long 
ag daétylits; ischinm ¢istinet ; carpus longer than ischium and merus together and 
as long as dactylus which is nearly twiee as long as propodus, with its main ter- 
minal spine almost as long as its own length together with that ol propodius. 
Pilth peracopod with earpus half as long again as propodns and little ware 
than Hwiee as long as merns, and a little shorter than basis. 
Pedinele of nroped about three-fourths as long as telsomie somite and shorter 
than endopod, including stont terminal spine of latter, which is not distinetly 
marked off; exopod including distal spine more than two-thirds length of endo- 
pod; endopod and pedunele cach with two small inner spines. 
Coloue lemon yellow, with faint shadings of brown on carapace.

Nhe only differences leaving doubt as to the identity of these examples are (1) 
the smaller size; (2) the relatively shorter earpus of the fifth peraeopod; (3) the 
slightly different proportions of the uropod. 
Arult male, General form as in furgiduld sp, nov, Fifth pleon somite nearly 
twite as long as wide and a little longer than ielsonie somite which is about half 
us long ugain as wide and is well produced posteriorly. 
First peraeopod with basis longer than ischium to propodns together; earns 
nearly half as long again as propodus, which is more than twice as long as dactylus. 
Basis of second peraeopod as long as remaining joints together, the latter as 
in female deseribed ahove. 
Fifth peracopod with earpus twice as long as propodus, two and one-half times 
as long 4s merus and little shorter than basis. 
Pedonele of uropod a little shorter than telsonic somite and five-sixths as 
long ss endopod melding terminal spine which, as in the females recorded 
above, is hot distmetly marked off; its imier edge hears a few short spines; exepod 
distinetly more than three-fourths as long as endopod whieh has six spines on 
inner margin, the last inserted just before the third fourth of length of ramus,

This genus was established on the female and was tentatively referred to the 
Bodotriidae. The male, now deseribed, has ¢xopads on the first three pairs of peraeo- 
nods (as in the female), pleopods are absent and the second antenna has a short 
and stout, prehensile flagellum. The mandible, as in Campylaspis, is moderately 
wide towards the hase but the iticisor process is narrow as in Cwmella (interior part 
oF base nol shown int [lale, 1936, tig. 8b). 
Picrocumea ths differs from all other Nannastacids in having an exopad oy 
(le third peracopods of the female and none on the fourth pair of the male. The 
gents in other respeers is wol typical of the family, ‘Che anterolateral eorner of 
(he carapace is not at all angular or prominent, the third maxillipeds are re.
