Tliere has come into my hands from Mr. Rohertyon, Govern- 

 ment Yeterinarj^ Surgeon, per Mr. S. S. Cameron, a l)ottle 

 containinu' " Portion of Kumen of Cow, worm attached, Sept., 

 '98," and hearing an additional hihe! with the following note: 

 — " CiotK/yloaenui, scii/ntiii/i (Leuckart. LS7G), natural habitat 

 oesophagus — no previous record as being in Rumen (Neumann, 

 '98)," this specimen having been identified by Neumann in 

 1898. As I have been uuiible to find any record of the occur-

There are 2 specimens, both females, one unattached being 

 12 cm. long, the other, of which the anterior part is embedded 

 in the wall of the rumen, has an exposed length of 7 cm. The 

 cuticular plates around the otherwise unarmed head end are 

 very well marked, varying considerably in size. The tubular 

 pharynx .55 mm. long, is succeeded by an oesophagus 8.8 mm. 

 long, the posterior ciid (tf the latter having a club-shaped 

 swelling .26 mm. in diameter. 



The posterior portion of the body is closely packed with ova.
