trace can be detected of the exite which is present in 
Anaspides. 
The maxilla (Text-fig. 8, mx.") has three endifces and a 
short unsegmented palp. Here also a certain resemblance to 
Koonunga may be traced in the fact that the endites 
are directed inwards, and not crowded together as they are 
in Anaspides.

constructed, only the inner ramus becoming a little longer 
and more slender in passing backwards along the series, and 
the group of spines arming the terminal segment being 
reduced to a single claw (with a minute seta at its base) in 
the last three pairs. The coxopodite is short, and has two 
vesicular epipodites on its outer surface. The basipodite is 
long, and both exopodite and endopodite articulate with its 
distal end. The exopodite shows an incomplete line of 
articulation near the base and another beyond the middle of 
its length, where there is a well-marked “shoulder” on each 
side; it is not, however, distinctly divided into two segments 
as described by Vejdovsky and myself. The endopodite 
consists of four segments, the precise relation of which to the
