HALE—AUSTRALIAN CUMACEA 77 
Colour: semi-transparent with dark stellate spots. 
Length 3 mm. 
Subadult female. The differences are best shown by a comparison of fig. 
4,A and C. The carapace is a little deeper and wider, the antennal notch is more 
open, and the fifth pleon somite is shorter than in the adult, while the second 
thoracic somite is scarcely backwardly produced dorsally. 
Length 2:6 mm. 
Loc. New South Wales, off Jibbon, 30 fath. (K. Sheard, submarine light, 
May 1943). Type ovigerous female in South Australian Museum, Reg. No. 
C. 2415. 
This species has a characteristic general facies owing to the emargination, 
near the hinder margin, of the dorsal edge of the large and robust carapace, the 
large antennal notch, the prominent ocular lobe, ete. 
C. sheardt has a somewhat similar elevation at the hinder end of the carapace 
but otherwise is so entirely different that it cannot be confused with gibba. 
CYCLASPIS LUCIDA sp. nov. 
Ovigerous female. Like the following species (mollis) in structure of cara- 
pace, pedigerous somites and pleon, and with the last. four pairs of peraeopods 
similar; the first peraeopods and the uropods, however, distinguish it, while the 
following comparative details may be noted. 
Antennal notch moderately open and tooth subacute (fig. 6, A). First an- 
tenna with basal segment of peduncle longer than second and third together, and 
with third longer than second. 

Fig. 6. Cyclaspis lucida, type female; A, first antenna and antennal notch; B, C and D, first, 
second and fourth peraeopods; E, uropod; E1, mucro of exopod of uropod (A to E, X 67; 
Cl, x 134; El, x 335).
