HaALE—AUSTRALIAN CUMACEA 429 
Jjohnstom. spp. nov, it is much as in the genotype but in tenuipes sp. nov, the first 
two segments are dilated to a greater extent and resemble more the contlition 
found in Sheardia, 
The gap between second and third peraeopods varies in the, species, as in 
Gynodiastylis. 
The integument is calcified and brittle and ig of a chaliky, somewhat opalescent, 
appearance in the female. It is translucent in the adult male, in which, ag pre- 
viously described, the carapace differe from that of the female and young mala 
to an extraordinary degree.

ALLODIASTYLIS HIRTIPES sp. nov, 
Oviwerous female. Tntegument with sparse, tiny granules, thickest on cara- 
pace, but present also on pedigerous and anterior pleon somites, 
Carapace less than oné-third of total length of animal, as deep as broad, and 
a little more than half as long again as wide; it has an elongate swelling (dorso- 
lateral fold) immediately below the frontal lobe, a small, rounded tumidity at 
each rear corner of frontal lobe and the median portion of last-named elevated 
and rounded; posterior to the frontal lobe the dorsum is coneave, the hollow 
emphasized by swollen lateral edges; on the sides is a large shallow depression, 
Antero-lateral margin very shallowly excavate; antero-lateral corner angularly 
rounded, armed with small denticles which continue along almost whole length 
of inferior margin. Pseudorostrum long, with spaced spinules below, very 
narrowly truncate in front; lobes meeting in front of ocular lobe for a distance 
equal to about one-third of total length of carapace. Frontal lobe broad; ocular 
lobe short, more than twice as wide as long, with no distinct: lenges, 
Pedigerous somites together more than half a3 long as carapace, not differing 
very conspicuously in length on the back; second with pleural parts produced 
forwards as small lobe; third produced fore and aft on the side, the second and 
third peraeopods being well separated. 
Pleon narrow, shorter than cephalothorax; fifth somite not. much longer then 
sixth, which is somewhat hroadened posteriorly, where it is slightly wider thau 
lone; telson slender, three-fourths as long again as sixth somite, with lateral 
margins serrate for greater part of length and with a pair of rudimentary spines 
at apex, flanked on each side by a similar lateral spine and a bristle, 
First antenna much as in genotype ; flagellum one-third as long ag third pedun- 
cular segment, two-jointed, the first. joint somewhat longer than the three- 
segmented accessory lash, 
Mandible with the usual nine to ten spines,
