but with uo outstanding teeth; carpus serrate on inner edge and with three small 
teeth on outer margin; propodus narrower but slightly longer than carpns; ser- 
ahr on inner edjre and twice as long aa daetylis. 
Wirst peraeopod with basis shorter than vest ol limb; mers one-third ns

as dactylus. 
Second peracopod not longer than first, with basis as long as ischium to pro- 
podus tovether; daetylus as long as carpus and propodus together and with one

Pedunele of uropoda subsylindrieal, serrate on inner margin, about two and 
nneshalf times as long as telsonic somite, and as éxopod; endopod scarcely longer 
than exopod, with five serrate spines on inner edge and a terminal spine more than 
half its length; exopod with slightly longer terminal spine and a shorter one 
Colour, pure mill white. 
Length, 4-3 mim. 
Loe. New South Wales; 5 miles east of Port Hacking; 100 metres, on mud 
(**Cronulla’’ Trawl Station, July, 1943); 4 miles off Eden, 70 metres, in sill 
(type loc., K, Sheard, Oct., 1943) ; 4 miles east of Port Hacking, 80 metres, on 
mud (K. Sheard, trawled, May, 1944). Tasmania: off Babel Island, lat, 39° 55’ 
S., long, 148° 31’ BE. (‘ Warreen’’ Station 29, Jan., 1939). Type female in South 
Australian Museum, Reg. No, C, 2526, 
As in some other species the ventral incubatory pouch of the ovigerous female 
is not bulging and prominent. In a female slightly smaller than the type (4-2 
thm.) eleven embryos, each 0-4 mm. in greatest length, cecupy almost all of the 
interior of the thorax. 
The tubercles of the carapace are so smal! that they are perhaps better de- 
scribed as granules. Subadult examples sometimes have these more numerous bat 
still smaller, and less conspicuous owing to a closer covering of short hairs. 
This species is somewhat close to thompsoni; the most apparent differences in 
the adult female are the shorter peduncle of the nropod and the narrower carapace 
with its small tubercles; the joints of the first and second peracopods are of differ- 
ent proportions. C,luticarpa Hansen (1920, p. 40, pl. iii, fig, 8) has similar senlp- 
(ure of the carapace bit the maxillipeds are very different. 
CAMPYLAHPIS BCHINATA Sp. NOV. 
Adult male. Integument thin, but tough and somewhat flexible; pleon more 
highly calcified and more brittle than thorax; rather coarsely retienlate on cara- 
ace. 
F ‘arapace With numerous small blun(-ended spiniform projections densely 
placed on back and sides, sparser infero-laterally ; at hinder margin the spines 
are longer and a pair of dorsal ones aré partieularly outstanding; interspersed 
is a sparse clothing of fine hairs; an elongate shallow depression on each side } 
an antero-lateral tumidity on each side, studded with spinules smaller than rest 
of armature; it is somewhat rectangular as seen from above, is depressed, twice 
as long as deep, and is barely as long as the pleon. Auteunal noteh listinel, rather 
narrowly excavate for the genus; angle rounded, margined with spines. Pseu- 
dorostral lobes widely truncate in front, meeting for a distance less than lewsth 
if oeular lobe which is narrow, dilated anteriorly and is nearly twice as lung as 
wide; uo corneal Jenses apparent. 
None of pedigerous somites elevated dorsally but second to fifth each with 
4 pair of outstanding spmes on back, those of fifth nearly as deep as the somite: 
other spines are placed on sides and back ol these somites while on dhe flattened- 
globose expanded pleural parts of gach isa Cau of four or five outstanding spines,
