ends. The first pair of pleopoda are modified so as to form an operculum 
covering the others; one of the plates, the outer I think, is long and broad 
so that it extends along the whole of the under side of the pleon; the inner 
plate appears to perform no special function, it is small and narrow, ap- 
parently becoming rudimentary (fig. 4 f). The sete on the pleopoda are 
long and fringed on each side with long plumes, which are exceedingly 
delicate. 
Cubaris rugulosus, Miers. (Cat. Stalk- and Sessile-eyed Crustacea of N.Z., 
This species was described by Mr. Miers from specimens in the collec- 
tions of the British Museum. His specimens appear to have been imperfect, 
for he neither describes nor figures the antennw. I have found it abund- 
antly at Kyreton, and also in the bush at Oxford. The inner antenne are 
very small and composed of three joints, the basal one stout, second short 
and narrowing distally, third about twice as long as the second, much 
narrower, with a few short sete at the end (pl. I., fig. 8 a). The outer 
antenne consist of seven joints. The basal one is short, the second and 
third subequal and rather shorter than the fourth; the fifth joint is the 
longest, and is longer than the flagellum, which consists of two joints, the 
first short, very slightly longer than broad, the second more than three 
times as long as the first and followed by a minute terminal joint which 
bears two or three short sete; the whole antenna, but more especially the 
distal portion, is finely hirsute, the hairs being short and delicate, much 
more so than can be shown in the figure (pl. I., fig. 8 4). 
In describing the last segment of the abdomen, Mr. Miers says: ** ter- 
minal segment much the broadest at the base, with the sides at first con- 
verging and then parallel,” In my specimens the sides after converging 
usually diverge slightly. 
The colour varies considerably. It is usually yellowish-brown with 
darker patches, but some specimens are uniformly black. 
Over the whole body the integument is covered with peculiar scale-like 
markings, each scale being usually more or less pointed at the end (pl. I, 
fig. 8 c). 
Philongria rosea, Koch. (Bate’s and Westwood's Brit. Sessile-eyed Crust., 
vol. ii., p. 460.) 
In a previous paper I have identified specimens found at Christchurch 
and Eyreton as this species, and at the same time adduced reasons for 
believing -that it could not well have been introduced from Europe. Since 
then I have found specimens precisely similar in the bush at Oxford, so 
that I think there can be little doubt that it is really a native of New 
Zealand and has not been introduced.
