Third maxilliped with basis granulate, a little longer than rest of appendage, 
with inner margin strongly toothed and a prominent tooth at inner apical angle; 
external distal angle not much produced, with one of the setae much stouter 
than the others, 
Developing marsupial plates and at least basis of perasopods studded with 
pranules, which become very small on posterior legs, 
First: peraeopod short, the carpus reaching little beyond antennal angle, the 
whole limb not much longer than carapace; with basis equal in leneth to remain- 
ing joints together, in part serrate on both marginge and with some conspicuous

teeth at distal end; propodus rather legs than two-thirds as long as carpus, a8 
long as ischiom and merus combined, and with four unequal distal setae, the 
longest more than twice as long as the joint; dactylus barely longer than propodus 
with oue of its distal setae very long; ischium and merus spiny. 
Second peraeopod only half as long as first, with the wide basis quite twice 
as long as remaining joints together and with a comb of flattened spines on inner 
edge; ischium distinct; merus broad, its width emphasized by four flattened 
crowded teeth on inner margin and a couple of less prominent. teeth on outer; 
carpus 4 little shorter than merus, subequal in length to propodus and with an 
inner tooth; dactylus little longer than propodus, with one of the distal setae 
very long; exopod, including its setae, much longer than the limb. 
Third and fourth peraeopods with basis much shorter than rest of limb, 
and merus distinctly longer than carpus and propodus together; one of the two 
distal carpal setae much stouter and a little shorter than the other! which, like 
the slender propodal seta, reaches to tip of the rather short, curved, and pointed 
dactylus. Fifth peraeopod shorter than third or fourth leg, but as long as second,
