agree in the main. It is very characteristic that the sculpture, con- 
sisting of a network of frames that enclose angular spaces, is wanting 
on the front part of the valves. It is also very characteristic, that 
on the sideparts of both valves, behind the middle, about halfway 
the posterior edge and somewhat nearer to the ventral edge than 
to the dorsal edge, a somewhat curved spine occurs which is turned 
slantingly towards the back. 
In the description, given by Brapy no mention is made of the 
fact, that in both valves a posterior part of a ‘Dorsalrippe” (11, 
p. 337) occurs, as is always the case with the remnants of Timor. 
Probably however this is also found in the recent representatives of 
this species, since as a matter of fact, Brapy says, that the dorsal 
edge is concave, as is also depicted in the figures. 
Recently these Ostracods have been found on the coast of Australia, 
near Caledonia, in the Chinese Sea and near Ceylon.

This Ostracod is only represented by a few loose valves. From 
the presence of the following qualities it appears, that these valves 
originate from a Cytherella species (8, p. 262). The valves are very 
firm and possess a small width, which augments towards the back. 
Consequently the carapaces are laterally flattened and seen from above 
wedge-shaped. Seen laterally, the valves are egg-shaped, while they 
get higher towards the end. 
The left valve as well as the right one has a furrow on its edges. 
With the first it is indistinct and of the ridges which bound this 
furrow, only the inner one can be seen very well, whereas on the 
other hand in the right valve the outer ridge is more prominent. 
With the closed shells therefore, the right valve must have over- 
lapped the left one on all sides. Therefore the shells are unequally 
valved. 
The “Verwachsungslinie” and the “Innenrand” coincide. They run 
parallel with the edges of the carapaces and at a small distance from 
those. The “Porenkanäle” are bifurcated and are at a considerable 
distance from each other. 
The musele impression, which is sometimes distinctly noticeable, 
is situated somewhat before the middle and closer to the dorsal edge
