16 FRESHWATER AND LAND CRAYFISHES OF AUSTRALIA 
and eight or nine spines on surface; some examples with three spines on 
lateral margins, and four spines on surface. Inner rami of uropods each 
with three sharp spines marking the obsolete median carina, three large and 
several small spines on outer lateral margin ; outer rami each with numerous 
sharp spines along tranverse suture. Lobes at base of uropods with a spine 
on upper lobe. 
Sternal keel moderately sharp; first pair of lateral processes small and 
round, increasing in size and sharpness to posterior, the latter large and 
deeply grooved. 
Great chelae stout, propodus twice as long as broad, upper margin with 
four small blunt spines, lower margin with a double row of numerous small 
sharp spines, cutting edge of propodus with two large and a few small 
tubercles ; dactylus with several small tubercles on cutting edge, and six or 
seven blunt spines on upper margin. Carpus with three long sharp spines on 
upper margin, upper surface deeply grooved; tnerus with four large sharp 
spines and a few small spines on upper margin. 
Habitat. — -New South Wales: Sydney (W. Kershaw, 1890); Wollon- 
gong; Parramatta River; Mt. Kosciusko; Blue Mountains. Queensland: 
Stanthorpe; Moreton Bay. Victoria: Bruthen (J. Barling, 1918); Narra-

(PL III, fig. 16.) 
Astacopsis kershawi Smith, Proc. Zool. Soc. Lond., 1912, p. 160. 
Rostrum, antennae, squame, interantennal spine and sternal keel as in 
E. nobilis. 
Carapace twice as long as broad, somewhat shorter than abdomen; 
branchiostegites sparsely studded with small tubercles. 
Abdomen as in E. nobilis, but telson and uropods longer. 
Great chelae as in nobilis but less spinose. Carpus with two sharp spines 
on upper margin, in some examples. 
Colour . — The colour varies from deep olive-green to mid bluish-green on 
carapace, abdomen, pereopods and great chelae, tinged with red on the tips 
of the spines and tubercles, and on the basal portions of the pereopods, the 
bases of the antennae, and on the posterior portion of the branchiostegites, 
and the membranous portion of telson and uropods. A few examples in the 
series are brownish-green, with the spines on body and the whole of the great 
chelae bright blue, pereopods dull reddish-brown. 
Habitat. — Victoria: Moe River (type locality) (W. Kershaw, 1886); 
Thorpdale (W. Kershaw. 1888) ; Bunyip River (W. Kershaw, 1888) ; Fern- 
tree Gully (S. W. Fulton, 1906) ; Warburton (F. J. Williams, 1905) ; 
Vereker Range, Wilson’s Promontory (J. A. Kershaw, 1913) ; Glenelg 
River, near junction with Limestone Creek (H. Pritchard, 1935) ; Crawford 
River (J. H. McEachern, 1936). 
Types in National Museum, Melbourne. 
Dana (1852) described and figured Astacoides nobilis, 
which he queried inhabited New r South Wales. Huxley (1880) 
considered nobilis identical with armatus ( serratus ) . Haswell 
(1882) quoted Dana’s description, adding that it was prob- 
ably identical with A. franldinii (Gray) . Faxon (1898) listed
