FRESHWATER AND LAND CRAYFISHES OF AUSTRALIA 
43 
A series of 24 specimens from the Otway Ranges and the 
type specimens of fultoni have been examined and compared 
with specimens from various localities in Tasmania. There is 
no character on which to separate them. 
Engaeus tuberculatus sp. nov. 
(PL IX, fig. 39.) 
Length of average adult specimen, 70 mm. 
Rostrum long and slender, apex upturned, long and sharp ; carinae sharp, 
half as long as rostrum, with three small tubercles at anterior end. 
Eyes large. First antennae with inner flagella very short and slender, 
about one-fifth as long as outer. Squame of each second antenna slender, 
ending in a long sharp spine. Interantennal spine short and broad, bluntly 
pointed, laterally produced at base. No exopod on third maxillipedes. 
Carapace longer than abdomen ; cervical groove and branchio-cardiac 
grooves well defined, areola fairly broad. Branchiostegites and anterior of 
carapace minutely tuberculate. 
Abdomen with small tubercle-like swellings, rather low and flattened, 
with a puncture on summit ; two rows on each segment. Telson broadly cone- 
shaped, without median or lateral spines ; inner rami of uropods rectangular, 
inner corners sharp and outer rounded, each divided by a longitudinal median 
carina reaching to posterior margin, without median or lateral spines ; outer 
rami each divided by a longitudinal median carina ending in a sharp spine on 
transverse suture, two or three spines along suture, suture placed at apical 
third of uropods. 
Sternal keel raised and fairly sharp ; first two pairs of lateral processes 
rudimentary, small but sharp below second pereopods, larger and rounded 
below third pereopods, deeply grooved; processes between fourth pereopods 
short and stout. 
Great chelae long and stout; propodus stout, twice as long as broad, 
bordered on upper, lower and posterior margins by a double row of small 
tubercles, cutting edge with one compound and three or four simple large 
tubercles, a smooth carina reaches from apex to base of upper surface of 
dactylus ; dactylus with two large tubercles on cutting edge, upper margin 
divided by a smooth carina, several small tubercles and punctures on upper 
margin ; carpus with upper surface covered by six or seven rows of small 
tubercles ; merus with a row of small tubercles on upper margin. 
Posterior pleurobranch rudimentary. 
Habitat. — Victoria : Sherbrook Falls (N. J. Favalora) ; Dandenong (S. W. 
Fulton); Warburton (S. W. Fulton). 
Types in the National Museum, Melbourne.
