Nematodes in Sheep 
In the following list I have adopted the nomenclature used by 
Ransom, synonymies have not been given, but to the correct names 
of the species I have in most cases added the older and more famihar 
names used in the majority of zoological and veterinary text-books. 
For complete descriptions and synonymies of the different species 
the reader is referred to Ransom’s monograph (1911).
