 This reference should be to Heterakis perspieillum.

 This large ascarid is fairly common iu our fowls though 

 not so abundant as the smaller Heterakis papulosa, Bloch. 

 iii. Heterakis compressa, Schneider, Monogr. d. Nemat. 1866, 

 p. 71. (South Australia.) 

 This parasite whs descn'Led from material collected from 

 South Australian fowls. Both Railliet 1 and Neumann 2 give 

 a summary of Schneider's account. Leiper' also refers to 

 it in describing an allied worm Heterakis uionitlttc, Leiper, 

 taken from the guinea fowl, Numida ptilorhyncha, Licht., 

 in the Soudan. I have taken specimens from a hen in 

 Sydney, which I regard as belonging to this species, as they 

 fully agree with the scanty account given by Schneider,

 (N.S.W.) 

 As mentioned before, this small nematode is very com- 

 mon in local fowls, especially in the caecum. I have also 

 taken it from the caecum of a turkey (vide infra) (N.S.W.)
