HALE—AUSTRALIAN CUMACEA 81 
of the carapace as a wider flattened area, giving the appearance of a faint double 
ridge. The length of the carapace is more than two-sevenths that of the whole 
animal; twice as long as deep, and widest at middle of length where it is dis- 
tinetly wider than deep. Antennal notch wide; antennal tooth subacute, with 
a short, obsolete ridge leading back from it for a short distance. Pseudorostral 
lobes meeting in front for a distance equal to only about one-fourth of length 
of ocular lobe. Ocular lobe prominent, elevated, very slightly longer than wide, 
and not constricted at base; it is darkly pigmented and ten black lenses are de- 
veloped. 

Fig. 9. Cyclaspis fulgida, type female; A, lateral view; B, cephalothorax from above; C, 
reticulate pattern and chromatophores of integument (A and B, X 20; C, x 175). 
Five pedigerous somites are exposed; together they are much more than 
half as long as the carapace; second somite as long as third and fourth together, 
smoothly tapering, and in side view continuing the even curve of the dorsal mar- 
gin of the carapace. 
Pleon with a faint median carina and with feeble articular pegs; first to 
fifth somites successively increasing in length, the fifth only one-fourth as long 
again as the fourth; telsonic somite as long as third, with shallow dorsal notch. 
First antennae relatively long; the first segment of the peduncle is as long 
as the remainder of the appendage; second joint stouter and longer than third, 
which is as lone as the two-jointed flagellum; apical appendages twice as long as 
flagellum. 
First peraeopods with carpus reaching level of antennal tooth; basis equal 
in length to remaining joints together, with a long plumose seta (reaching be- 
yond apex of merus) at external apical angle, and two projections at inner angle, 
one being prominent. and tooth-like (fig. 10, B1); carpus, a little shorter than 
propodus, which is almost one-third as long again as the slender dactylus. 
Second peraeopods stout, with basis longer than remaining joints together ; 
ischium with a plumose seta; merus as long as carpus and propodus together, 
with a spine at inner apical angle and a plumose seta at outer; carpus with two 
subapical spines, the inner stouter than the outer, and with inner apical angle 
acutely produced ; propodus barely more than half as long as the stout dactylus, 
which is equal in length to the longest of its strong apical spines.
