Peduncle of uropod slender, not quite as long as telson, nnarmed except. 
for a single inner spine near distal end; exopod nearly three-fourths as long as 
pedunele, and longer than endopod, with five slender spines on outer margin, 
one (subdistal) on inner, and a terminal spine shorter than its second joint; 
endopod divided into three segments, with twa, one and three inner spines respec- 
tively; distal and proximal joints subequal in length, each longer than second 
joint; terminal spine (which has a small outer spime near its base) as lony as 
second and third joints together, 
Colour cream, Length 3:0 mm. 
Adult male, Differs little from the female excepting for the following: 
First peraeopod shorter, the carpne reaching only to level of apex of pseuclo- 
rostrum, and pleon. more slender, The telson, as in the female, hag ouly rudi- 
meniary terminal spines, 
The second antenna has the flagellum a little longer than the peduncle and 
enmposed of eleven to twelve joints. 
b Basis of third maxilliped slightly longer than rest of limb; serrate an inner 
ge. 
The first to fourth peraeopods have well-developed. exopods. 
Uropod with peduncle distinctly longer than telson ; endopod almost as long 
as exopod, and two-jointed but with a third segment (comparable to that of 
female) marked off by a fused suture; there is one inner spine on pedineld as 
in female and the inner spines of endopod segments are three or four, two and two. 
Length 2:6 mm, 
Loc. New South Wales: 4 miles off Eden, 70 metres, in silt (K. Sheard, Oet,, 
1948) ; Wadulla, Brush Island, 45 fath., in fine silt on flathead grounds (type loe,,

The remarkable structure of the first peraeopod is a characteristic feature; 
this and the long setae of the posterior peraeopods, together with the elongate 
telson, ure distinctive. 
‘A female from off Eden, $+5 mm, in length and with developing marsupinm 
was dissected and figured, 
Dicowes srevipactyua (Hale). 
Die brevidactylum Hale, 1937, p. 69, fig, 6-7. 
Ovigerous female, New South Wales form. It would seem that this bears the 
same relation to the types as do eastern coast examples of gome of the other species 
which occur also in South Australia, One may cite for instance Cyclaspis eretuta 
(Hale, 1944, p, 91) and Bodotria maculosa (Hale, 19448, p. 226) ; it is possible 
that the differences may prove constant enough to warrant subspecific rank, 
In this case the thorax and its appendages are as in the South Austrakian 
types, but the difference lies in a general elongation of the animal. The female 
is slightly smaller than the type (2°5 mm. as against 2-7 mm.) but the telson is 
relatively longer, reaching beyond the distal end of peduncle of uropod, while 
the first five pleon somites together are equal in length to the eepbalothorax instead 
of shorter than it, The branchial siphons are remarkably long, about three- 
fourths the length of carapace, In the first peraeopods one of the terminal dactylar 
getae and one near distal end of propodus are stout and almost spine-like. 
Small exopods are present.on the first to fourth peraeopods; thege are similarly 
developed in the type female. Although all haye peduncle and flagellum they are, 
as previously noted, quite rudimentary, with short setae; those of the first pair
