silt (type loc,, K, Sheard, trawled Oet., 1945) ; 4 miles cast of Port Haeking, $0

Museum, Ree. No, C. 2517. 
C, aspera is close to antarctica Calman (1907, p. 5, pl. i, fig, 14-16 and text 
fle. 4; and 1915, p. 155, fig, 9), Tn the last-named, however, the merus of the third 
maxilliped is much smaller, being considerably less than length of carpus and 
propodus combined. It likewise resembles the Northern verrucosa Sars (see Han- 
sen, 1920, p. 45, pl. iii, fig. 8a) but differs in the strongly developed transverse 
suleus of the fifth pleon somite, the shorter peduncle of the wropod and in hay 
ing the tubercles of the carapace less fattened. 
CAMPYLASPIS THETIDIS sp. NOV. 
Female. integument strongly calcified. 
Carapace studded with rounded tubercles, which tend to fall into rows; sides 
with two parallel longitudinal ridges, bounding a large subquadrate, depressed 
area al top and bottom: the upper carina is strongly tuberculate and extends from 
above the antennal notch Lo beyond second third of carapace; the lower ridge is 
less markedly tubereulate; above the upper carina there is a longitudinal dorso- 
lateral tuberculate elevation and towards the front is the usual antero-lateral pro.

others. The back of the carapace is marked with a very fine median line anteriorly 
but is longitudinally snleate for the greater part of its length, the furrow expanded 
posteriorly over the cardiac region where there is a short median longitudinal ea- 
rina, which is one-sixth of the length of carapace. Viewed from above the cara- 
pace is snbquadrate, abont as wide as deep and not quite two-thirds as wide as 
long; tt is as long us pedigerous and first to fifth pleon somites, Pseudorostral 
lobes narrowing to the front, very oblique in lateral view, and meeting for a dis- 
tance equal to three times length of ocular lobe, which is small, longer than wide, 
and with no appareut corneal lenses. Antennal notch wide but distinet: angle 
with small clenticles, subacute, 
Pedigerous somites each with a pair of low dorsal tubercles near hinder 
margin; first and second dorsally very short but slightly elevated; pleural parts 
of second to fifth expanded and inflated, in second rounded laterally, in lust 
three angular and slightly produced backwards. 
First two somites of pleon with transverse dorsal carina, from which branch 
off a pair of short longitudinal ridges, which are faint on the first: third to fifth 
somites each with median earina (rugose owing to prostrate serrations) and a 
similar transverse ridge crossing it near posterior end; fifth with a second enllar-
