LOCOWEED DISEASE OF SHEEP 421 



D. DISCUSSION OF PARASITIC DISEASES ENCOUNTERED. 



During the summers of 1903 and 1904 thirty-two autopsies were per- 

 formed; twenty-eight are included in the preceding report, one other was 

 upon an experimental' 'locoed" sheep at White Sulphur, Montana; three au- 

 topsies upon cattle have been discarded as they were performed hurriedly 

 and were unsatisfactory. In the twenty-nine autopsies on sheep the prin- 

 cipal diseases and parasites observed were:

The Thysanosoma actinioides, or Taenia fimbriata, or "fringed tape- 

 worm" has attracted attention in this country chiefly from Curtice, (4th 

 and 5th Annual Reports, Bureau of Animal Industry, 1887-1888; pp. 167,- 

 186; also "The Animal Parasites of Sheep," Washington, 1890; also Vet.
