[Read Utli July, 1910.] 



Some time ago Professor Gilruth, as Director of the Veterinary 

 Eesearch Institute of the Melbourne University, handed me a 

 small phial containing " tapeworms from fowls." with a request 

 for their identification and report. Since then I have collected 

 endoparasites from a number of chickens from Victoria. The 

 following contains the results of these observations, together 

 with the record of two forms sent from Queensland fowls by 

 Dr. Sydney Do-dd, Chief Veterinarian and Bacteriologist, 

 Brisbane, and of one from Dr. H. Cumpston, Chief Health 

 Officer, Perth, West Austraba. 



CESTODA. 



Clwanotaenia infundibulum (Bloch, 1779), Cohn, 1899. 



This cestode appears fairly common in the suburbs of Mel- 

 bourne, and has not been previously definitely recorded from 

 any part of Australia. 



My specimens of this species show in over 60 per cent, of 

 cases a somewhat smaller diameter of the head, viz., .33 mm., 

 and sometimes even less (.31 mm.) instead of the normal .4: mm. 

 The head seems always conical. The suckers are generally .17 

 to .22 mm. long, and .068 mm. in transverse diameter; the 

 rostellum has a rather greater width than usual, viz., .08 to 

 .1 mm., while the hooks it carries vary in number from 11 to 22, 

 have the characteristic shape, and are .024 to .03 mm. long. 



Davainea cesticillus (Molin, 1858), Blanchard, 1891. 



This cestode of fowls has been previously recorded for 

 Australia, onlv from New South Wales, bv Mr. T. H. Johnston
