DR. M. KHALIL ON THE NEMATODE 



MURSHIDIA FALCIFERA Collbolcl, 1882. 



Strongylus falcifer Cohbold, 1882. 



Nematode No. 3. Evans & Rennie, 1910. 



Strongylus falcifer Mitter, 1912. 



Cylicostomum falciferum Raillet, Henry & Bauche, 1914. 



Murshidia falcifera Lane, 1914. 



The oral aperture is bounded by eight}^ rays. The bursal rays 

 have not the rugged outline seen in M. murshida. (For measure- 

 ments see Table I.) 



Mitter in 1912 gave a short description of this nematode with

 of the dorsal ray. In either case this may be attributed to 

 inaccuracy. 



Habitat. Intestine of Indian elephant (India).
