First peraeopod with basis barely as long as rest of limb; merns, carpus and 
propodus wide, subequal in length; dactylus half as long as propodus with one of 
the three distal setae longer than itself. 
Second peraeopod longer than first, with the stout basis mueh shorter than 
rest of limb, but longer than ischium to propodus together ; dactylus as lone as 
mernus and carpus together, with a curious distal lobe, alongside which are inserted 
(he two terminal setae, the longer of which is half as long as the joint. 
Pedunele of uvopod triangular in section, the apex of the median ridge and 
both edges jaggedly serrate; it is half as long again as telsonic somite and three- 
fourths as long again as the subequal rami; endopod serrate on both edges, with a 
toothed dorsal ridge and with two stout terminal spines, one very short; exopod 
wilh serrate edges, its apex with a stont spine, whieh is longer than that of ende- 
pod, and a tiny spine. 
Colour, yellow. 
Length, 6°6 mm.

Although he makes no special comment regarding it, Culman’s fieure of the 
second peraeopod of rostrata (1905a, pl. ii, fig. 37) shows that in that species also 
the distal seta of the dactylus, though much shorter, is sublerminal, the end of the 
jomt projecting beyond its insertion; further, the joimts of this appendage are of 
the same proportions as in thetidis which, however, exhibits obvious differences in 
body sculpture and has a shorter pseudorostrum. 
Hansen (1920, p, 42, pl. ii, fig. 5) illustrates the second and third maxillipeds 
of rosteata; the second pair are much as in thetidis but io the third the merus is 
narrower and the carpus relatively smaller,

This stable, widely distributed genus, is much more sparsely represented hy 
species than is Campylaspis. It is well-defined, particularly in the character of 
ihe vake-like daetylus of the second maxilliped and the strikingly long ischium of 
the first peraeopod. Six species have been deseribed previously and the first Aus- 
tralian form is recorded below.
