The leeches from Palestine, being preserved in alcohol, cannot be 
expected to have retained their original colours. Traces of the lateral 
orange stripes appear in some of the small specimens in bottle (<x). 
The large specimen contained in (a) could extend itself during life 
to at least twice its present length, that is, to a length of more than 
100 mm.; the two examples taken from the human throat are probably 
about half grown. 
Limnatis nilotica has a wide distribution extending from the Azores, 
through Northern Africa and Egypt to part of Western Asia. It is a 
species to which the term “ Horse-leech ” has been applied and it has 
been often confused with the European Horse-leech, Haemopis Savigny 
[= Aulastoma Moquin Tandon]. 
Savigny, whose figures are incorrect in certain respects, gives 
excellent drawings of this leech in a contracted and extended state and 
of the characteristic triangularly grooved lip referred to in my description 
of a leech from Angola \Parasitology, vol. I. p. 186]. 
A considerable literature exists relating to accidents caused by this 
leech, of a similar nature to those recorded by Dr Masterman. 
Blanchard has collected much curious information on this point and 
gives many references.
