HALE—AUSTRALIAN CUMACEA 165 
nearly half as long again as the propodus, and the endopod of the uropod is three 
times as long as the pedunele; as these differences are constant in a long series of 
South Australian specimens the latter are now regarded as representative of a dis- 
tinet species. 
N, subinflatus oceurs in the same situations as inflatus ; it may be distinguished 
by the smaller size, the different shape of the carapace and the proportions of the 
peraeopods and uropods; it will be noted that the inner margin of the endopod cf 
the last-named (as in zimmert) bears two short spines in the female and five in 
the male as against three and six in the sexes of inflatus and johnstom.

Although the eyes are much closer together than is usual in the females of 
species of Nannastacus, they are paired; each has three corneal lenses and is sepa- 
rated from its fellow by a distance less than its breadth. The larger eyes of the 
males of brachydactylus Calman and nasutus Zimmer are similarly narrowly sepa- 
rated. 
An ovigerous female recently collected in Table Bay, Tasmania, has the form 
slightly more robust than in South Australian examples, is a trifle smaller (1°3 
mm.) and the granulation of the integument is quite distinct. The antero-lateral 
corner of the carapace is subacute and the lower margin immediately posterior to 
it is serrate. The third maxilliped has an exopod. The peraeopods are much as 
described for sheardi but the carpus of the fifth peraeopod is less than half as 
long again as the propodus. 
A few subadult males from Tasmania have the uropods as in the female 
excepting that exopod and pedunele are very slightly longer in relation to the 
endopod, which has three distal spines distinctly marked off on inner margin. 
The fifth pleon somite, as in the female, is only half as long again as wide. 
NANNASTACUS JOHNSTONI sp, nov. 
Ovigerous female. Integument almost smooth, shining, sparsely clothed 
with long hairs. 
Carapace relatively large and robust, three-sevenths of total length of ani- 
mal and nearly three times as long as pedigerous somites together ; across the in- 
flated branchial regions it is wider than deep, while it is less than twice as long as 
deep; the antero-lateral regions are somewhat swollen, there being a noticeable 
lateral depression between these tumidities and the swollen branchial areas; back 
of carapace rather flat, slightly rounded along midline and with a median tumidity 
at hinder end. Antero-lateral margin angularly coneave and antero-lateral angle 
well marked, produced and subacute. Pseudorostrum directed upwards, the lobes 
gaping above and below, and not meeting to any appreciable extent ; front of lobes 
as seen from side rounded and subtruneate, with indefinite serrations. 
Pleural parts and a narrow strip only of first pedigerous somite exposed ; 
second also very short dorsally (where it is elevated) but like first and third 
ereatly expanded laterally and wider than the carapace; fourth and fifth somites 
each with back slightly raised. 
Pleon somites short and stout; first deeper and wider than long, with dorsum 
tumid ; fifth longer than the others, but Jess than half as long again as wide; tel- 
sonic somite rounded posteriorly, barely longer than wide, 
Third joint of peduncle of first antenna shorter than second and less than 
half as long as first.
