Trematodc worm or 



Rci^Mrdin.t,^ these parasites in 

 poultry, The'diald (Parasitic 

 Diseases of I'Dultry. London) 

 says : "The Trematodc worms 

 or Fhikes found in ihc fowl are 

 3 in number. ( )ne is found in 

 the egg (Distoma o-ratimn, the 

 otlurs in tlTe oesophagus and in- 

 testines." 



"The Fluke found in the neso- 

 l>ha,!4Lis of the fowl is known as 

 CcphaIo(joiii)}iiis pcllitcidus, a 

 transparent reddish fluke about 

 9 mm. long. These were found 

 by Von Linstow and Railliet. 

 In the intestines Neumann enu- 

 merates 7 species, namely, Noto- 

 cotylc triscrialis Distomc oxycc- 

 phahim, Rud., D. dilatatum, 

 Miriam. D. lincarc, Zeder, D. 

 ovatiim, D. armatnm, Molin, and 

 Mcsogonimus commutatus, Sons. 



These, however, are not all dis-

fluke showing intern a 

 structure. (From Thomp- t'^^'t ; dilatatum is undoubtedly 

 son after Sommer). the same as oxyccphalum ; arma- 



tnm is also probably the same." 

 "None of these Trematodc worms are of any pathological im- 

 portance, although, as is well known, they often cause serious 

 malaflies in other animals. All the Flukes that have two hosts 

 underg) a complicated metamorphosis, the early stages always 

 taking place in some water-molluse. Those found in Galliis do- 

 jucsficits have not had their life-histories worked out."
