INTESTINAL NEMATOIDS OF SHEEP. 



Ascaris Ovis. Very rare. Male, two to three inches long ; 

 female, &s much as 4 inches and 2 mm. thick. Head small, 

 mouth trilobate, the upper lobe with two papillae, the others with 

 one each. Vulva toward the anterior third of the body. 



Strongylus FilicolUs (filum thread, collum neck). The 

 thread-necked strongyle is so named because of the extreme 

 tenuity of the part succeeding the small head, which has two 

 small, translucent, lateral alae. Male, 8 mm. to 15 mm. long, 

 filiform with two spicula and broad membraneous clasping organ. 

 Female, 16 mm. to 24 mm. long ; head and neck filiform ; caudal 

 portion somewhat thicker ; tail conical, pointed ; anus close to 

 caudal end, with vulva in front of it. Ova elliptical. 



Habitat. Duodenum and small intestine of sheep and goat 

 (exceptionally in the fourth stomach). Often present in vast 

 numbers in sheep affected with strongylus contortus (stomach), 

 and strongylus filaria (bronchia). It abounds in autumn and 

 winter. 



Pathogenesis. It causes much intestinal irritation with diar- 

 rhoea, and by its abstraction of blood and producing indigestion 

 is a fruitful source of anaemia, emaciation and dropsy. Associ-
