I ENTOZOA. 1 1 7 



The last reference is to the occurrence of the parasite in 

 Fijian fowls, and is inserted here in order that it may not 

 be overlooked. I have recently recognised the worm in 

 material collected from a hen in the Sydney district. This 

 parasite (D. echinobothrida) frequently imbeds its scolex 

 and part of its strombila so deeply into the mucosa and 

 submucosa of the fowl's intestine that it produces a nodule 

 or " tumour " somewhat comparable to those produced by 

 the larvae of the nematode Oesophagostomum colutribtomim 

 Curtice, in the intestinal walls of sheep, and by the larvae 

 of Oes. radiatum, Rud. (syn. Oes. infiatum, Schn.) which 

 infests the ox, both of these nematodes being commonly 

 met with in these hosts in New South Wales. The con- 

 dition produced in the fowl is usually called the "nodule 

 disease," or more correctly "nodular Taeniaisis." 

 v. Davainea sp., Bradshaw, I.e., p. 50. (N.S.W.) 

 vi. Choanotaenia infundibulum, Bloch., (syns. Taenia infun- 

 dibuliformis, Gorze, Mono r ylidiu,n infun dilndnm, Bl.). 

 N.8. Wales, not previously recorded. 

 I have now identified these as D. tetragotta, Molin. 



vii. Cysticercus sp., Perrie, I.e., p. 821. (N.S.W.) 

 I have seen Perrie's specimen, which resembles a hydatid 

 in appearance. I am inclined to regard it as Eehinococcus 

 veterinorum, Rud. (E. polijmorphus, Dies.). Brown 1 

 mentions the occurrence of hydatids in fowls, but does not 

 state whether they occur locally. He 2 also mentions two 

 other tapeworms, viz. Cliotiiiotacnid infiiiidihuhnn, Bloch, 

 and Davainea proglottina, Davaine, but does not refer to 

 any locality. The latter of these parasites should be 

 • omitted from the list of our known entozoan fauna until 

 recognised by some worker in parasitology. The nematodes 

 and cestodes mentioned by Bradshaw as occurring in a 

 fowl were identified by me.
