the chelipeds and the tips of the great chelae carmine ; tubercles on the biting edges 
dull carmine at the base, cream-buff above ; legs greenish glaucous blue, deep greenish 
glaucous at their extremities ; chelae on 1st two legs dark olive-buff. 
(Colour names taken from Ridgway’s “ Colour Standards and Nomenclature,” 
1912 .) 
It may be noted that specimens of the well-known A. serratus have been 
received from such localities in Southern Queensland as Tamborine Mountain and the 
Lamington National Park. McCulloch 1 has also recorded specimens from near 
Stanthorpe, and made notes on the variations in colour that these crayfish exhibit. 
It is evident that A. serratus has a far wider range than that recognised by Geoffrey 
Smith 2 , who regarded the Blue Mountains as its northern limit. 
In view of this discovery, it is interesting also to note that Astacopsis was 
recorded by Nobili 3 from Sorong, New Guinea, from a specimen collected by D’Albertis. 
Later authorities, 2 and 4 however, regarded this as a probable mistaken locality. 
Special efforts are being made by members of the North Queensland Naturalists’ 
Club to obtain additional material.
