ON A COLLECTION OF PARASITES FROM THE SOUDAN ‘ 611 
there can be little doubt and probably we shall not go far wrong 
in assigning them to the sub-family of Ligulinae, but we cannot go 
much further and the assignment of Leuckart and Cobbold of their 
larvae to the genera Bothriocephalus and Ligula appears to me 
hardly justified especially when we consider the arrangement and 
distribution of the muscular system. 
NEMATOMORPHA 
1. — Caorpopes Hawkeri Camerano. 
This new species has been described by Professor L. Camerano, 
of Turin (1). 
It is interesting not only as a new species but as the first to be 
described from the district in which it was found. Some of the 
specimens of the worm were found in a tin of waler placed for the 
cat and afterwards others were taken in the bilge-water of the 
boat. Probably they had escaped from the body of some Insects 
which had fallen into the water, but we have no direct evidence 
of this. 
_ Professor Camerano points out that this new species shows some 
affinity with Chordodes tuberculatus described by von Linstow (2?) 
from the Lake Nyassa where it was dredged at a depth of 160 metres. 
ACARINA 
4. — RaipicepHALUS SxrpLeyi Neumann. 
Two males and three females were taken from the skin of a 
Hyæna. They form a new species the description of which, by 
Professor Neumann, of Toulouse, will appear in this Archives 
immediately.
