Uropod with peduncle slender, iwo-third as long again as telsonic somite 
and with six short spines (as well as usual minute spinules) ol inner margin; en- 
dopod, as in female laevis, two-thirds as long as pedunele, but with seven spines 
spaced along length of inner margin and with loug terminal spine three-fourths 
as lony as ramus; exopod as long as endopod, with longest of the two unequal ter- 
minal spines almost as long us its second joint, 
Length 1:6 mm, 
Adult male, Carapace more than one-third of total lenyrtlt of animal; three- 
fourths as long again as deep and as wide as deep. Psendorosiral lobes meeting 
for a distance equal to less than one-third length of ocular lobe, which is large, 
folly as wide as long, rounded and with seven large corneal lenses, Antero-lateral 
mhargin concave and angle obtuse. 
Pedigerous somites together four-sevenths as Jong as carapace; pleural parts 
of first concealed, those of remainder slightly expanded, 
Pleon not much shorter than cephalothorax; fifth somite hall’ as long again 
us telsonic somite, which is (as in female) little longer than wide and not markedly 
produced posteriorly. 
Peraeopods with joints, apart from the longer basis, of same proportions as 
in female, 
Uropods with peduncle fully twice as long as telsonic somite; endopod two- 
thirds as long as pedunele and with terminal spine more than three-fourths as long 
as ramus; exopod with longer terminal spine almost as long as whole ramus; other 
armature of rami and pecdunele as in female. 
Length 1-6 mm.

While only a single ovigerons female was taken by Mr, Munro's surface uet- 
fings, males are abundant in the night hanls mentioned, but only three were 
secured at Station 1. 
Although as aforementioned, the uropods in their slenderness and propor. 
tione resemble those of laevis, their armature, constant in the series, is quite dis- 
tinetive. 
CUMELLA CANA 8p, Noy, 
Cumella laeve Wale (nee Calman), 1936, p. 432, fig, 20-21. 
The differences between the southern Australian material and the female 
deserihed by Calman are disenssed wh supra, The uropods in cuna have the pe- 
dunele wider, less than six tines as long as broad (about ten times in Jacris), ser 
rate on inner edge and with the terminal spine of the endopod barely half the 
length of the ramus instead of fully two-thirds as long ax it; normally there are four 
inper spines on this ramus in the male but rarely there are five; the endopod in the 
female hag three or four inner spines. The name is given in allusion to the grey 
colouration. 
In fig. 18 the appendages of cana ave compared with those of meunrod, ‘The 
former differs in that (1) the first peraeopod has the carpus Ionger (han propodiis 
and daetylus together, and the lamellate spines at the edge of the exopodal recess 
of the basis are stronger; (2) the aeeoud peraopods have the dactylis much shorter 
fia merus and carpus togeiher: (8) the daetylus of the fifth peraeopod is 
shorter: (4) the uropods are stouter, with different armature and with pedunele 
shorter in relation to telsonie somite and endopad.
