somite, with lateral serrations fine, amd with the two terminal spines flanked on 
each side by a shorter spine. 
First antenna with first joutt of pedunele long, projecting well in front of 
carapace, and longer than second and third joints together; second. two-thirds as 
long as third, and equal in length to the two-jointed main flagellum, which. is 
twice as long as accessory lash. Second antenna three-jointed, only about one- 
third as long as first pair. 
First and second maxillipeds with basis short (see figures). 
Third maxilliped elongate, its dactylus reaching forward to level of middle 
of Jength of pseudorostrum; basis narrow, slightly dilated distally and a little 
longer than rest of appendage; carpus, propodua and dactylus subequal in length, 
the last-named slightly the longest. 
First peraeopod with merus reaching almost to level of antennal angle; basis 
distinctly more than one-half of rest of limb (when extended) ; propodus equal 
in length to merus and less than half as long as carpus; dactylus more than two- 
thirds as long as propodus; propodal and dactylar setae longer than ischinm, 
merus and carpns together. 
Basis of second peraeopod shorter than rest of limb; ischium relatively large; 
carpus nearly twice as long ss merus, and longer than propodus and dactylus 
together; dactylus a little shorter than propodus and with distal setae longer 
than the joint. 
Posterior peracopods robust, aa usual without trace of exopods, and with 
merus in all considerably longer than basis; earpus, propodus and dactylus short, 
together not much more than half length of merus; carpus with one of the distal 
setae enlarged to form a blunt-ended, stout spine, which reaches almost to tip of 
dactylus (fig, 13, bottom left) ; propodal seta stout ( but more slender than above- 
mentioned carpal seta) tapering to the subacute apex. 
Pedunele of wropod less than one-third as long again as telson, broad (less 
than four times as long as breath) excavate longitudinally on interior face and 
with a row of eight or nine spines on inner edge; rami subequal in length; endo. 
three-fifths as long as peduncle, with its proximal joint equal in length to the other 
two subequal joints; first joint with four inner spines, the others each with one, 
and second with one at inner distal angle also; terminal spine half the length of 
ramus; exopod with two imequal terminal spines, one slightly longer than that 
of endopod, 
Colour white. Length 9:3 mm. 
Adult male, Cavapace much as in female, but the antero-lateral angle is less 
emphagized, and the oenlar lobe slightly larger ; it is three-fonrths as long again as 
pedigerous somites, which together are shorter than in the other sex, First pedi- 
ferons somite concealed on sides. 
The pleon is one-tenth as long again as the cephalothorax. The lateral spines 
of the telson are almost as long as the terminal spines. 
Exopods ave present on the third maxilliped and first to fourth peraeopods; 
those of the last two pairs of legs are smaller than the others, but have peduncle and 
five-jointed flagellum, furnished with lang plumose setae. The appendages other- 
qvige are as in the female excepting for trivial differences; there are five instead of 
four spines on the first joint of endopod of uropod, 
Length 8:2 mm. 
Loe, New South Wales: Ulladulla, 75 metres (K, Sheard, A, Trawl, mesh 40, 
July, 1944). Types.in South Australian Museum, Reg. No. C. 2654 and 2681. 
This form is larger than any of the other species of the genus. The division 
of the endopod of the rather massive uropod into segments is much more distinctly 
marked than im some other members of the group haying this ramua trisegmentate 
aud the setae of the thoracic exopods are comparatively well-developed and 
strongly plumoseé,
