joint. The propodus and dactylus of the second peraeopod do not differ much 
in lenyth, 
The carpus of the fifth peraeopod is less than half as long again as propodus. 
The pedunele of the wropod is twice as long as the endopod or a little longer ; 
the endopod bears about seven spines on the inner margin and its terminal spine is 
fully half as long ay the ramus. 
As in the male of brachydactylus Calman (1905, p, 14, fig, 83—female un- 
known) from seas north of Australia the eyes are placed close together; nasutus 
apparently differs in no important feature from Calman’s species excepting that. 
the peduncle of the uropod is relatively a little longer, and the endopod of that 
appendage carries a long instead of a very short spine. 
NANNASTACUS NASUTUS Var, CAMELUS Zimmer. 
Nannastacus nasutus vay. camelus Zimmer, 1914, p. 186, fig. 13; Hale, 1987, p, 
73, fiz. 9, 
This variety was previously recorded from the female only, Males, from a 
nuuiber of South Australian localities, have the dorsal convexity posterior to the 
eyes not so prominent as in the female and, even so, varying somewhat in degree 
of development,

Big. |. Nawnastacus nasitis var. camelus, adult male; « pace, ocular lobe and pseudo- 
rostrum (X 64); ant. 1, first antenna (x 74; flagella, x 270) $ mxp. and prp., third maxilliped 
and peracopods (% 74); urop., uropod with fifth pleon and telsonie somites (> 74). 
Adult male. Psendorostral lobes meeting for a distance equal to about 
one-fourth of total length of carapace, and with their anterior ends coarsely 
serrate; they meet for their whole length and do not diverge near apices; eyes 
each with three corneal lenses, the innermost separated from its opposite fel- 
low by only about one-half the diameter of 2 lens; a low but distinet median 
carina runs from pseudorostrum to posterior margin of earapace.
