4. — FrzaRiA SUDANENSIS von Linstow (pl. VIL fig. 9). 
This new species taken from the Lion and from the Hyæna in 
the Soudan has been kindly described by Dr von Linstow. He sug- 
gests that it may be identical with F. leonensis Gmelin and Rudol- 
phi (1), but that this is a nomen nudum. D: von Linstow gives the 
following description which I have translated. 
« Cuticle thick, finely ringed ; deeper transverse rings irregu- 
larly arranged at wider intervals ; head-end somewhat thicker 
than the tail, both rounded ; four papillæ in a ring on the head : 
oral opening a small funnel which leads into a tube lined with 
chitin which is continuous with the cuticle. 
Male about 4mm Jong (the single specimen ot this sex wanted 
the head), Omm39 broad ; tail-end 0mm062 long ; two very unequal 
spicules, the right thick and straight, 0®m93 long, the left slender 
and eurved, Omm27 long ; on each side ten papillæ, six præ-anal 
which become smaller from before backwards, one para-anal and 
three post-anal. 
Female up to 162mn in length and Onm51 broad ; œsophagus 1/21 
of the body length, anus almost terminal, 0"m044 from the tail- 
end on which there is a small finger-like prolongation not piercing 
the cuticle ; vulva very far forwards 1mm87 from the anterior end; 
the immature egg small Onm010 long and 0mm0052 broad.
