rami narrow, apically acute; endopod a little shorter than exopod, longer than 
peduncle, and with twenty finely serrate spines on inner edge; exopod longitu- 
dinally excavate interiorly, where the proximal third bears plumose setae, which 
are a little stouter than those of the peduncle. 
Colourless, transparent. 
Length, 4-4 mm. 
Non-ovigerous female. Carapace almost one-third of total length, with 
striae, ete. as in male, but with dorsal edge more arched, and with length much 
less than twice the depth. In dorsal view it is barrel-shaped, widest at middle 
of length and relatively narrower than in male, the breadth being less than two- 
thirds the length, and equal to the depth. Thoracic appendages much as in male 
(fig. 14, D-F). 
Pedunele of uropoda less than one-third as long again as telsonic somite, 
without setae; the narrow, apically acute rami are longer than the peduncle; the 
endopod has twelve spines on inner edge; exopod with six tiny incisions in inner 
margin. 
Colourless except for a few brown chromatophores on carapace and fourth 
peraeon somite. 
Length 3-6 mm. 
Loc. Queensland, off Fraser Island; lat. 24° 20’ §.; long. 153° 02’ KE.

C, 2412-2413. 
The two available specimens have the integument not at all calcified, but 
this may be due to a recent ecdysis; species taken with them are indurated. 
CYCLASPIS SHEARDI sp. nov. 
Adult male. Integument calcified, but delicate and brittle; surface finely 
pitted (reticulate) and with larger granules which, though about four times as 
wide as the reticulations, are still small and inconspicuous. 
Carapace with dorsal edge very slightly arched, elevated in a distinct hump 
near posterior end, its depth equal to greatest width and more than half its 
length, which is two-sevenths of total length of animal. Pseudorostral lobes 
barely meeting in front of ocular lobe and with anterior margins truncate and 
slightly sinuate; dorsum with a median longitudinal carina, on each side of 
which, near the posterior end, there is a large pit; the upper edge of each pit 
is raised and smooth. Ocular lobe large, as wide as long and with nine promi- 
nent, darkly pigmented lenses. Antennal notch widely open; antennal tooth 
subacute; a faint ridge leads back for a short distance from the tooth. 
The four exposed pedigerous somites together are more than half as long as 
carapace and each has a distinct. dorsal carina; the second fits intimately against 
the carapace and its dorsal contour continues the hump of the back, then curves 
sharply down; third to fifth somites with postero-lateral angles backwardly pro- 
duced in the form of rounded lobes. 
Pleon relatively massive; the first three somites much deeper than the last 
pedigerous somite ; articular processes small but distinet ; first to fourth and tel- 
sonic somites subequal in length, fifth half as long again as fourth; the groove 
indicating the fused telson is unusually distinct; there is a distinct dorsal carina 
for whole length of pleon, terminating at this groove, 
First antenna with basal joint of peduncle fully as long as remainder of ap- 
pendage; second joint stouter than third and subequal to it, and to the two-jointed 
flagellum, in length; sensory terminal filaments moderately long. 
Basis of second maxillipeds half as long again as remaining joints together. 
Third maxillipeds with basis nearly twice as long as palp and with outer distal 
merus reaching to level of articulation of carpus and propodus.
