108 PARASITOLOGY. 



The condition produced by the genus Strongylus 

 is called Strongylosis. 



The condition produced by the genus Sclerostoma 

 is called Sclerostomiasis. 



The condition produced by the Stephanurus is 

 called Stephaniasis. 



The condition produced by the genus Syngamus 

 is called Syngamosis. 



The condition produced by the genus Oesophag- 

 ostoma is called Oesophagostomiasis.

The heads of some are provided with papillae ; 

 others are nude, while some have a buccal armature 

 consisting of membranous teeth. 



Some infest the stomach and the small or large in- 

 testines ; others are found in the fat around the kid- 

 ney and in the lungs, etc. The male is provided 

 with a caudal pouch which may be a single pouch or 

 divided into two (bilobate). The caudal pouch is 

 composed of finger-like projections or ribs ; stretch- 

 ing from rib to rib is a delicate membranous expan- 

 sion which forms the pouch, the ribs acting as sup- 

 ports. Two spiculae, usually of equal length, are 

 observed. In some species they project beyond the 

 pouch, others scarcely to its posterior border. The 

 caudal pouch is used to clasp the female during th 

 act of copulation.
