Cuitton.—Some New Zealand Amphvpoda. 271 
agree closely with specimens of similar size from Port Jackson, New South 
Wales, the type-locality. In none of them are any of the segments pro- 
duced into definite dorsal teeth, but all have the posterior margin of the 
third pleon segments serrate, as described by Stebbing for Ewsiroides caesar, 
though in one or two instances the teeth are rather indistinct, thus 
approaching the condition found in E. crassi. 
e species has been recorded from South Africa by Barnard, from 
Ceylon by Walker, and from the Gambier Archipelago by Chevreux. Of 
the two specimens from the latter locality, one was a female bearing 
young, though only 4 mm. in length. Of them Chevreux says, “ Chez 
ces exemplaires, le bord postérieur des plaques épimérales du dernier 
segment du métasome, moins convexe que chez le type, ne présente que 
des crénelures peu distincts." 
If Bovallia gigantea Pfeffer is considered as belonging to the same species, 
corresponding to the form described by Stebbing under the name Fusiroides 
crassi, then the range of the species is extended to the subantarctic and 
antarctic seas to the south of South erica. 
I have been able to compare my New Zealand specimens with examples 
of Eusiroides della-vallei Chevreux from Banyuls-sur-mer, on the south 
coast of France, and can find little difference between the two.

This species was described from specimens obtained in streams on 
Mount Mihiwaka, near Port Chalmers, at heights up to about 1,000 ft. 
above sea-level. Later on Mr. G. M. Thomson collected it in similar 
localities on Mount Maungatua and other hills in the neighbourhood of 
Dunedin. During the expedition of the Philosophical Institute of Canter- 
bury to the Subantarctic Islands of New Zealand in 1907, specimens were 
taken in fresh-water pools and streams on Enderby Island, Auckland 
Island, and Campbell Island, at places not far above sea-level. These 
specimens differed from the type in having the palm of the second 
athopod in the male oblique instead of transverse, and prove to be 
the same as С. subtenuis Sayce, a species found in New South Wales, 
Victoria, and Western Australia. 
In Dec 
s were living was quite fresh, but the sea-water would reach the place 
at high tide. Both specimens were deeply pigmented of a dark-grey colour, 
while the Port Chalmers specimens are usually much lighter, some being 
almost white. The Riverton specimens resemble those from Mount Mihi- 
waka so much that they must be considered as belonging to the same 
species, but there are some slight differences. The second gnathopod of 
the male (fig. 1)* has the palm quite transverse, and the dactyl has a rounded
