First peracopod with slender terminal joints together more than half as 
long again as basis; ischium with a sirung distal onter spine and merus wilh 
snitler spme in same position ; carpus aid propodus subequal in leneth, and dae- 
lylus less than two-thirds as long as either, 
Second peracopod with basis about equal in length to remainder of limb; 
carpus sibequal in length to dactylus and twice as lony as merus; dactylus three 
times as long as propodus, with longest terminal seta equal in length to prapodus 
plus dactylus. 
Filth peraeopod with carpus more than halt as long again as prapodus, whieh 
is longer than the dactylus. 
Pedunele of nropod more than half as long as telsonic somite and less (han 
one-third as long as endopod exclusive of its terminal apine; ¢xopod nearly halt 
as long again as pedunele, half as long as endopod and with its distal apine reach- 
ing to Just beyond distal end of last-named ; terminal spine of endopod stout, two- 
Hlths as lony as its ramus, 
Ovigerous females have the rani of the uropod relatively shorter (endopud 
wuirely more than twice as long as peduncle, and exopod as long as pednnele) ; dis- 
lal spines of same length in proportion to rami. 
Almost mature males (lig. 16, juv.) with lateral body spines as in the femaie, 
have the rami of the uropod intermediate in length between those ut ihe ovigerous 
female and adult mule. 
wo males trom Moreton Bay, Queensland (1oW-net at night, Nov —Dee., 1940, 
LS. R. Munro) ave smatler than the southern specimens (1+5 mm.) and differ in 
having the spinnlation of the carapace far less developed, with the spine helow 
pscudorostral lobes jnsiguificant. In oe of them the dorsal processes of the 
pleon somites are more slender and there are no fairly large spines near the hase of 
the long and prominent apical spine of each elevation, the slope of which bears only 
small spinules; the second male has the pleon armature as figured. 
Genus CUMELLA Sars, 
Cumella Sars, 1864, p. 198; Calman, 1911, p, 844 (key) ; Stebbing, 1913, p. 178 
(syn. and key), 
Nine species can be added to the genus since Stebbing’s revision, three {ron 
the Northern Hemisphere (Hansen, 1920, pp, 29-30, pl. ii, fig, 4-5 and Tart, 1930, 
p. 15, fig. 5, A-D) three from South-Western Australia (Zimmer, 1914, pp. 179.- 
182, fig, 4-9), and three now proposed, 
Zimmer has suggested that Vannastacus hirsutus Havsen should be referred 
to Cumella because of the close set eyes of the female. Cwnella lima Vale (1936, 
p. 435) has the eyes separated by a very narrow interspace in the female but it is 
new cousidered that the species belongs to Nannastacus. 
It is perhaps scarcely practicable to deseribe newly discovered species so ex- 
haustively as to preclude any possibility of confusion regarding others subse- 
quently found. Wor example Cumella hispida and laevis Calman muy be men 
tioned. ‘There oeeur in Australian waters several forms distinct from each other 
and allied to these two speeies bul apparently separable from them. One of 
these. from southern Australia was lorinerly recorded provisionally as laevis 
(Hale, 1986, p. 432) ; another, now available from Queensland, is, in the prapor- 
tions of the wropods, still closer io /aews but the armature of these appendages 
is diferent. The relatively slight features distinguishing these {wo Australian 
forts from /aewis, as deseribed from the Gulf of Siam, are constart in long series 
and both are herein regarded as new; eventually they may be considered varie. 
lies or subspecies but in any case separate riames seem to be desirable. 
The status of the material lerein referred to hispida remuins in some doubt 
pending further details of the species,
