peraeon and pleon segments are dorsally carinate and produced to a more 
‘or less acute tooth but these teeth are sometims obsolete. In the form 
described by PFEFFER under the name Dovallia gigantea these segments 
are carinate but the teeth only subacute and in them the posterior margin 
of the pleural plate of the third segment of the pleon is slightly convex 
and entire while in other forms this margin may be partly or wholly 
serrate. While the intermediate forms appear to be too numerous and 
the transitions too gradual to justify the eontinued recognition of different 
species it is possible that the forms may develop either in the direction 
of Bovallia gigantea as described above or of the form originally described 
by Mr. STEBBING under the name Zuszroides caesaris in which the dorsal 
teeth are more acute and the posterior margin of the third segment of 
the pleon is serrate. I have discussed the species in some detail in the 
two papers quoted above. 
Eurymera monticulosa Pfeffer.

CHILTON 1912, p. 493. 
This species, originally described by PFEFFER from South Georgia, 
has more recently been fully redescribed and figured by CHEVREUX from 
specimens from Graham Land (Booth Wandel Island). A single specimen 
from South Orkneys was in the colleetions of the „Scotia“. 
In most respeets it appears to correspond with those forms of the 
family Pontogeneiidae in which some of the joints of the flagellum of the 
upper antenna are enlarged on the under side but it differs from them 
in the transverse dorsal ridges and the longitudinal lateral elevations of 
the peraeon.

Stebbingia gregaria PFEFFER 1888, p. 110, pl. 2, fie. 7. 
This is an exceeding]y common species in Subantaretic seas and 
being dominant and widely spread it presents in some localities local 
varlations and in some cases it is very difficult to decide whether these 
should receive separate names or not. With Stebbingia gregaria PFEFFER, 
however, there is no diffieulty, for the examination of the specimens in 
the Hamburg Museum shows that they are quite the same as those
