The larger tapeworm here associated with D. varians was 

 D. cesticillus. 



NEMATODA. 



Hetercd-is perspirillum (Rudolphi, 1803), Schneider, 1866. 



This was found in the small intestine of 25 per cent, of the 

 fowls examined from Victoria, and then not above 20 to 50 in 

 number. It is also represented in my collection by a few 

 specimens sent by Dr. H. Cumpston, from West Australia. 

 It is already known from New South Wales (Cobb, 1896, p. 

 747; and 1898, p. 316), and Johnston (1909, p. 412), and "in 

 ovo " (Cobb, 1905, p. 561). Probably also the Ascaris sp., re- 

 ported from New South Wales by Perrie (1892, p. 821), was 

 this species. 



Heterakis papUlnsa (Bloch. 1782). Railliet, 1885. 



This nematode appears to be common, as is usual in other 

 countries, in the fowls around Melbourne — practically every fowl 

 examined having at least a few of these worms in either small 

 intestine, rectal caeca, or rectum, while in some cases they were 

 very numerous. 



This has previously been recorded for Australia by Cobb 

 (1896, p. 748), and Johnston (1909, p. 412), from New South 

 Wales only, though it is probable also that the Oxynris sp. 

 recorded from New South Wales by Perrie (1892, p. 822) was 

 this species. 



ah; Heteralyis inaculosa (Rudolphi, 1802), Scliueider, 1886. 



Among the specimens of 77. papulosa taken from the rectum 

 and caeca of a fowl are 3 imperfect male specimens of some form 

 of Heterakis, which does not exactly fit into any of the known 

 species of that genus. 



The body, which is 12-13 mm. long, is thick and very trans- 

 parent, sharply tapering anteriorly and only slightly posteriorly. 

 The mouth is surrounded by three very well-marked lips, the 

 superior being slightly the largest, and each lip has a papilla 

 in the centre of its base. No lateral wings are visible on either
