HALE—AUSTRALIAN CUMACEA 187 
First peraeopod with merus only one-third as long again as carpus, which is 
much longer than propodus and twice as long as dactylus. 
Dactylus of second peraeopod almost as long as carpus and propodus together, 
and with longest terminal seta half as long as the joint. 
Pedunele of uropod three times as long as the short, broad and little produced 
telsonic somite, but only two and one-fourth times as long as endopod; with spaced 
plumose setae on inner margin; endopod with three terminal spines, the outer- 
most very small, and with nine or ten spines on inner margin; exopod a little 
shorter than endopod with the longest of its two terminal spines fully as long as 
its second joint. 
Colour white. 
Length 3-8 mm. 
Loc. Tasmania: off Babel Island, lat. 39° 55’ S., long. 148° 31’ KE. (‘*War- 
reen’’ Station 29, Jan., 1939). Type in South Australian Museum, Reg. No. C. 2566. 
(’, similis may be separated from thompsoni without dissection by the different 
proportions of the joints of the first peraeopod and by the shorter peduncle of the 
uropod. 
CAMPYLASPIS UNISULCATA Sp. NOV. 
Adult male. Integument calcified and brittle, with reticulate pattern small, 
rather diffuse on carapace and of somewhat imbricate appearance on pleon. 
Carapace with obseure, very fine median dorsal line; smooth on sides excepting 
for a single longitudinal, faint, slightly eurved furrow running from neighbour- 
hood of antennal notch to about four-fifths of the length ; depressed and with dor- 
sal margin little arched ; fully twice as long as deep, and distinctly less than half

the total length of animal ; viewed from above it is suboval in shape with the antero- 
lateral areas below the lateral groove prominent, while the sides are not quite 
evenly curved but slightly sinuate. Antennal notch shallow, smoothly concave ; 
below it the margin is rounded, not at all angular. Pseudorostral lobes subtrun- 
cate and slightly concave in front, meeting for a distance equal to about haif 
length of ocular lobe, which is rounded, large, rather wider than long and with 
three prominent lenses arranged in a triangle, the hinder ones situated at and 
beyond the postero-lateral parts of the lobe. 
First pedigerous somite concealed excepting for a narrow dorsal strip; it 
and the second elevated dorsally and with anterior margin as seen from above 
slightly produced forwards and angular medianly ; third a little elevated posteri- 
orly on the back; fourth and fifth somites with a pair of low longitudinal dorsal 
ridges ; pleural parts of second to fifth rounded, not much expanded backwards.
