Last thoracic segment unarmed in the female, in the male wit 
a mesial process. 
(2) Campecopea (Leach). 
The section Monolistrini comprises three (probably four’) 
genera closely allied to each other, but distinguishable by at 
least one practical character. 
(a) Urp. consists of the sympod and an elongate movable 
exp. 
(3) Monolistra (Gerst.). 
(3) Urp.consists only of a verysmall oblong-triangular joint. 
(4) Cae cospheroma (Dollf.). 
(y) Urp. wanting. 
(5) Vireia (Dollf.). 
The section Cassidinini comprises four genera, three of which 
are exceedingly characteristic, while the fourth, Chitinopsis 
(Whitel.), has only sub-generic value. 
(a) Seen from above, the epistome protrudes as a rather or 
very long process separating the antennule. Two proximal 
joints of the antennulz considerably or exceedingly expanded 
in front of the head. Lobe of fifth joint of the maxillipeds 
rather long, proceeding only from the proximal part of its 
inner (front) margin (fig. 6a). Endp. of plp.! oblong, but 
not fully twice as long as broad. Exp. of plp.* two-jointed. 
Terminal margin of abdomen freely exposed, rounded without 
notch. 
(t) Body rather broad. Two proximal joints of the antennulze 
considerably expanded. Endp. of plp.' only somewhat longer 
than broad. 
(6) Cassidina (M.—Kdw.). 
(tt) Body oblong-oval. Two proximal joints of the anten- 
nule exceedingly expanded. Endp. of plp.’ almost twice as 
long as broad. 
(7) Chitinopsis (Whitel.). 
1 The genus Speleosphxroma belongs probably to this section, but 
is omitted, as not only the animal, but the recently published description is 
unknown to me.
