HALE—AUSTRALIAN CUMACEA 93 
side below the pseudorostral suture and behind the dorso-lateral excavations are 
faint indentations, lending a suggestion of a coarse squamose pattern. Antennal 
notch moderately wide, with a very faint short groove leading back from it; a short 
rounded ridge runs back from the narrowly rounded antennal tooth, giving it a 
subacute appearance. Pseudorostral lobes truncate and slightly sinuate in front, 
barely meeting in front of ocular lobe. Ocular lobe wide, constricted at base, 
roundly subtriangular, as wide as long, and with nine prominent lenses; strongly 
pigmented. 

Fig. 20. Cyclaspis cretata, paratype male; A, first peraeopod and A1, distal end of its basis; 
B and B1, second peraeopod; C, third peraeopod; D, uropod. E, Terminal joints of first peraeopod, 
of allotype female (A to H, X 67; Aland B1, K 134). 
The four exposed pedigerous somites together are much more than half the 
length of the carapace; each has a faint median longitudinal carina; dorsal edge 
of second slightly rounded, descending steeply from the level of the hinder edge 
of carapace; third and fourth with the usual lateral subtriangular area distinctly 
delineated, each as long as the slightly expanded pleural portions of second. 
Pleon somites each with a fine, thin ridge; somites one to five with obsolete 
dorso-lateral carinae and (like fifth peraeon somite) with the sides tumid fore 
and aft, a shallow groove between the elevations; articular processes small but dis- 
tinet ; first four and telsonic somites equal in length; telsonic somite with dorsal 
notch moderate. 
First antenna with second segment almost as long as third, and stouter, the 
two together much shorter than the basal segment. 
First peraeopod with carpus just reaching level of antennal tooth; basis 
barely longer than rest of limb, its apex with a long exterior plumose apical seta 
(reaching beyond distal end of merus) and with two tooth-like projections, the
