Metopella ovata (Stebbing). 
Metopella ovata Stebbing, 1906, p. 183 ; Chilton, 1912, p. 481. 
I have two small specimens from Brighton, Otago, which I refer to this 
species. One is a female, about 3mm. in length, and agrees closely with 
Stebbing's description and figures ; it has the palm of the second gnathopod 
transverse, and that of the first nearly so; in these respects it agrees with 
the South Orkneys specimens that I referred to M. ovata in 1912, with one 
of which I have been able to compare it. The other Brighton specimen, 
taken at approximately the same time, shows no brood-plates or other 
distinetive marks of sex, and is possibly a male; in it the palms of both 
gnathopods are much more oblique; it agrees so closely in all other 
respects that I think it must be considered as belonging to the same species. 
In both specimens, which have been stained with eosine and mounted 
in Canada balsam as micro-slides, certain structures which appear to be of 
a glandular nature have been deeply stained in the side-plates and other 
parts of the body but not in the appendages ; these show as groups of 
small round bodies with straight ducts leading towards the margin of the 
side-plate. They appear to be similar to the structures figured by Stebbing 
(1891, pl. 1, prp. 4) in the basal joint of the fourth peraeopod of Urothoe 
elegans, though I cannot find that these are referred to in his text. 
" Metopella ovata is now known from the South Orkneys, the Strait of 
Magellan, and from New Zealand.
