INTRODUCTION. 
This memoir presents the results of the study of a number of specimens of 
Filariid worms from Cattle and other Ruminants which had accumulated 
during the last few years from various collections of Nematodes, sent to me 
for identification and laid aside for further investigation. 
I am indebted to Professor G. H. F. Nuttall, F.R.S., for two of these col¬ 
lections: (1) Helminths from Wassein, Burma, sent by Dr H. H. Marshall, and 
(2) from British East Africa, collected by Mr R. E. Montgomery, of the Nairobi 
Veterinary Pathological Laboratory. A third collection was obtained from 
Northern Rhodesia by Mr H. E. Hornby, Government Veterinary Surgeon, 
whilst my materia] also includes some specimens sent by the Department of 
Agriculture, Reduit, Mauritius. 
The Filariids from these various sources all proved to belong to the group 
of species now separated from the genus Filaria s. str. and placed by Railliet 
and Henry (1911) in the genus Setaria Viborg 1795. Altogether thirteen 
species have so far been referred to this genus, of which ten have been re¬ 
corded as parasites of Ruminants; of the latter only two are at all well known, 
namely Setaria labiato-papillosa (Aless.) and S. equina (Abildg.), the second 
species essentially a parasite of Equines but stated to have been observed in 
Cattle also (Stossich, 1897). The remaining forms from Ruminants have for
