Filariid Parasites of Ruminants 
variable in number (Text-fig. 1 C). The lateral appendices of the tail are large 
and situated about 0*12 mm. from the posterior extremity. 
Anus about 0-5 mm. from the posterior end of the bodw 
Vulva somewhat variable in position, 0*45-0*75 mm. from the anterior 
extremity. 
Eggs thin-shelled, measuring 0*03-0*046 x 0*02-0*03 mm. 
Setaria digitata (v. Linstow 1906). 
v. Linstow’s type-specimens were obtained from Bos indicus in Ceylon; 
I have referred to this species a number of worms collected by Dr Marshall 
sjj i c.2. 
Fig. 2. Setaria labiato-papillosa (Aless.). Lateral view of caudal extremity of 
male, x 220. 
from the peritoneal cavity of Domestic Cattle at Wassein, Burma. Unfortu¬ 
nately only female specimens are represented in the material; these agree 
fairly well in their measurements with those described by v. Linstow. I have 
however given a somewhat different interpretation to the structure of the 
organs surrounding the mouth. 
The species is evidently very closely allied to S. equina (Abildg.), the type 
species of the genus. 
Specific diagnosis. Setaria: Head not separated from the body which 
tapers gradually to the anterior extremity.
