HALE—AUSTRALIAN CUMACEA 99 
Basis of second peraeopods as long as rest of limb; merus subequal in length 
to carpus and propodus together, and to propodus and dactylus together; carpus 
with three spines ; propodus two-thirds as long as dactylus, which is equal in length 
to the longest of the stout terminal spines. 
Setae of fossorial limbs as in pura, fig. 3, F. 
Pedunele of uropoda about one and one-half times as long as telsonic somite, 
and one-fourth as long again as endopod, with marginal setae; exopod with eight 
plumose setae set in serrations on inner margin; endopod a little shorter than 
exopod, its inner margin with setae on proximal third and thence with a row of 
thirteen short and rather slender spines. Both rami narrow, the subacute apices 
without terminal spines or mucrones. 
Colour white, with smoky patches and large black chromatophores. 
Length 5 mm. 
Loc. New South Wales: Cronulla, 8 feet (K. Sheard, submarine light, Sept. 
1942, 8 to 8.20 p.m.) Type in South Australian Museum, Reg. No. 2423. 
Only males were taken. They are similar to the males of pura, but are sepa- 
rated by the following characters: The carapace lacks a faint antennal ridge and 
the dorsal margin of the second pedigerous somite is more oblique. The first pe- 
raeopods have the segments of different proportions, the basis being relatively 
longer, and the dactylus shorter. The dactylus of the second peraeopods has 
stouter and slightly shorter terminal spines. The uropods are very different, the 
exopod having no terminal mucrones, and the endopod being furnished with a 
long row of many more and shorter spines. 
levis group (0). 
Carapace not at all compressed, almost globose, the back broadly rounded, with very fine but 
distinct, median carina; pseudorostral lobes barely meeting in front of the rather small ocular 
lobe. 
Apices of both rami of uropods simple. 
A pusilla-like assemblage limited to four species. 
CYCLASPIS GLOBOSA sp. nov. 
Subadult female. Tntegument indurated, with coarse, clear-cut reticulation. 
Carapace almost globose, one-third of total length of animal, and overhanging 
the pedigerous somites, so that, seen from above, the second and all but the lateral 
portions of the third are hidden by it (fig. 25, B) ; widest at the middle of its length, 
where it is slightly broader than vertical depth, which is equal to three-fourths of 
the leneth; dorsum with a fine, unbroken, median carina for whole length. An- 
tennal notch deep and not widely open; antennal tooth large, subacute. Pseudo- 
rostral lobes just meeting in front of eye-lobe, truncate in front. Ocular lobe mode- 
rately large, subtriangular, slightly longer than wide, not constricted at base and 
with colourless lenses at sides and apex. 
Four pedigerous somites exposed ; together they are more than half as long 
as the carapace, the second somite is not. longer than the others and its short dorsal 
margin (as seen from the side) slopes sharply down from the carapace, which 
bulges above it; each somite with a median carina for whole length. 
Pleon longer than thorax, slender ; each somite swollen and with a fine median 
carina but no other sculpture; first to fourth and telsonic somites subequal in 
length ; articular pegs small but much more distinct than in clark. 
First antennae with basal joint of peduncle long, almost equal in length to 
remaining joints together. 
First peraeopods with carpus reaching level of antennal tooth; basis one- 
fourth as long again as rest of limb, the apex with an external, plumose seta, and
