In my “ Revision of the Genus Stilesia^ ” I had to leave several 
points in the anatomy of Stilesia globipunctata (Riv.) undecided, as 
the material I had of the worm was too macerated to allow of any 
definite conclusions. At the same time I pointed out, that the 
topography of the male canals as described by Stiles and Hassall" 
disagreed with the conditions obtaining in Stilesia hepatica Wolffhiigel, 
in other respects a very closely related species. The necessity for 
a re-examination of Stilesia globipunctata (Riv.) in order to decide 
whether the differences really exist, or whether they were supposed 
to do so, on account of the material examined by Stiles being rather 
macerated (loc. cit. p. 74), was all the greater as Stilesia globipunctata 
(Riv.) is the type species of the genus Stilesia. Through the kindness 
of Mr Littlewood, Chief Inspector of the Veterinary Department, I was 
able to obtain living examples of Stilesia globipunctata (Riv.) at the 
Cairo abattoir on Jan. 27, 1912. These worms have been fixed with 
Zenker’s solution, hardened and cut. 
Stilesia globipunctata (Riv.) when living very closely resembles 
Stilesia hepatica Wolffhugel. Both worms have in common a certain 
gelatinous appearance commented on by Dr Giles, quoted by Stiles 
and Hassall {loc. cit. p. 74). Both are of approximately the same 
size, and are extremely contractile. My new specimens, when found,
