carpus and as long as propodis and dactylns together; longest terminal dactylar 
spine not much shorter than earpns, propodus and dactylus together, the other 
two unequal, 
Last three pairs of peraeopods with basis becoming successively shorter; 
longer than rest of limb in third, a little shorter in fourth and only as long as 
ischium merus and carpus combined in fifth; setae see fig. 3, I. 
Pedunele of uropods shorter than telsonie somite and serrate on outer side : 
endopod serrate on inner margin, slender, without apieal spine, one-sixth as long 
again as peduncle and a little shorter than the exopod, which bears slender setae 
on inher margin and two minute apieal mucrones, 
Colour milky white, without markings,

The lateral elevations are more spinose or more aehte in some examples 
than in those Wlusteated; the upper and lower antero-lateral elevations are often 
conjoined on each side, but still retain their character as distinct projections. 
CYCLASPIS AUSTRALIS Sars. 
Myelasms australis Sars, 1887, p. 12, pl. i, fig. 1-20; Calman, 1907, p. 7, Steb- 
bing, 1913, p. 38. 
Aars' types from Victoria were subadult. A considerable series now available 
nakes it possible to amplify the original deseription, 
Omgerons female (8mm, to 9 mm.), The carapace is about two-thirds as lang 
us deep; in dorsal view It is widest in posterior balf where it. is three-fourths to five- 
sixths as long as the medial length. The median longitudinal carina hears a 
double row of small tubereles. At the first fourth of its length, each side of the 
curapace tas two low anterotateral tubercles, from the lower of which runs 
downwards and backwards an obsolete ridge. Behind the middle of the length 
is Ww transverse carina (much more defined than the anterior) runing from the 
median ridge a little forwards, then forming a decided angle (postero-lateral 
tubercle) with its eurved lateral continuation, whieh meets the feeble anterior 
carina near the iferior margin of the carapace; a low, oblique, swollen dorgo- 
lateral ride extends from the postero-lateral prominence to the antero-lateral fi1- 
hereles, The pecigerous and pleon somites are as described by Sars. 
The surface is pitted, with the edges of the pits raised to form an il-marked 
reticulate pattern. In certain lights these define a faint antennal ridge, 
In the first peraeopods the basis is distinctly longer than the rest of the limh 
and hears 4 seta at external apical angle and a shorter one at inner angle; the 
carpus is shorter than the propodus (of equal length in Sars’ fiz. 16) and longer 
than the dactylus.
