the first four pleon somites have feeble dorsal tubercles on the: mid-lne—these are 
wholly absent in the female. 
Only one spine is present on the carpus of the seeond peraeopods, tut the 
terminal dactylar spines are identical (fig, 30, C and @).

The above-mentioned fish is trawled in Australian waters to a depth of at 
least. 100 fathoms. The specimen examined had been feeding upon Bodotria sp., 
Hemilamprops sp., Diastylids, C. pinguis, etc. ; most of the stomach contents were 
jin fair condition, and include several new species of Cumacea, 
The third to fifth peraeopods are as in clardi, but as mentioned, are less robust. 
Apart from the distinctive shape of the carapace the two species show many dis- 
similarities. In pinguis the pleon is markedly more slender, the three terminal 
spines of the second peraeopods are all of different leugths, and the surface retieula- 
tion is larger and clearly defined. 
Seen from above, the thorax is of distinctive character in each of the species

A large number of examples from Spencer and St. Vincent Gulfs, and Kan- 
garoo Island, South Australia, are now available; some specimens were taken from 
the stomach of a Mullet (Mugil cephalus) by Prof. T. Harvey Johuston, The 
following additional notes are tiecessary to the original deseription, 
The sides of the carapace rise steeply to the sharp median dorsal carina. The 
carina is distinct on the second pedigerous somite and although faint is present 
on all the remaining somites; there are also indications of dorso-lateral carinae 
on those of the pleon. 
Viewed from above the carapace differs in shape in the sexes. In non-ovi- 
verous females it is widest at about the middle of its length and the sides are 
evenly rounded (fig. 31, H). In the male it is very slightly widest towards 
the front aud the sides are less curved, Ovigerous females (fig. 31, G) have the 
varapace widest in the posterior half and tapering towards the front, The ocular 
lobe (fig. 31, 1) is wide in both sexes (almost as wide as long) roundly sub- 
triangular in shape coustricted at base, generously pigmented and with nine 
large lenses, the three in the middle dark, the lateral ones pale. There is a faint 
ridev, discernible only with difficulty, riiuing back for a short distanee from 
the antennal noteh. 
Five pedigerous somites are exposed always in the ovigerous female, but 
the first is concealed in males und subadult females. 
The apex of the basis of the first peracopod has (he usual apical external 
plumose seta (which reaches to the middle of the length of the carpus) and a 
shorter internal seta; ihe carpns is harely longer than the propodus, whieh is 
little longer than the ductylus.
