HALE—AUSTRALIAN CUMACEA 123 
Subadult females (New South Wales), show the surface patterning well. 
The front of the pseudorostral lobes, the antennal tooth area and part of the 
lower edge of the carapace are finely reticulate; beyond these portions there oc- 
eurs a coarse reticulate or squamose pitting with diameter about six times that 
of the small reticulations, which are continued on the edges of the secondary 
reticulation. 

Fig. 43. Cyclaspis usitata, newly moulted, transparent adult female; A, cephalothorax; 
B, first antenna; C and D, second and fourth peraeopods; E, uropod, Juvenile, 2:3 m.m.; 
F, cephalothorax; G, fourth peraeopod; H, uropod (A, X 16; B, Cand G, X 72; D and H, X 45; 
I, X 26; H, x 116). 
The anterior transverse carina is distinct and is elevated medianly to form 
a small dorsal tooth; thence as it continues downwards on each side it crosses two 
low tumidities which are slightly concave immediately in front of the carina, so 
that a tooth-like prominence results. In some eases the upper of these projec- 
tions is angular and almost spine-like. The ‘‘blunting’’ of these features in the 
type female may be due to age. 
In lateral view the profile of the narrow ocular lobe is straight; thence the 
dorsal outline rises obliquely to the first transverse carina, but is quite unbroken 
by tooth or tubercle; between the two transverse carinae the margin is very 
slightly concave and posterior to it is arched upwards and downwards; at the 
hinder end of the back the median conical elevation is large. 
In dorsal view the carapace is of equal width where crossed by the trans- 
verse carinae. 
The stout uropods are less than twice as long as the telsonic somite; the 
pedunele is a little shorter than the endopod, which is slightly longer than the 
exopod, and six times as long as wide.
