T4 NOTES ON SOM^ ENTOZOA. 



The male spicules are slightly curved pointed rods, 

 measuring 1-05 mm. in length, and -022 mm. in widtli. 

 The male tail is not prominent, the alae being narrow. 

 The sucker lies at some distance (-275 mm.) in front of th^ 

 cloaca. There are two pair of prominent pre-anal papillae, 

 a, small unpaired median pre-anal, and a small unpaired 

 post- anal papilla, followed by six paired post- anal papillae, 

 the arrangement of these sensory structures being indicated 

 in the figure of the tail end of the male. (Fig. 25). 



Heterakis papillosa, Rud. 



A common parasite of poultry (Brisbane), but hitherto 

 unrecorded from this State. 



Heterakis perspicillum, Rud. 



More commonly known as H. inflexa. A fairly common 

 but apparently unrecorded nematode infesting local fowls 

 (Brisbane). 



Heterakis spumosa, Schneider. 



Present in Mus decumanus and M. rattus (Brisbane). 

 Not previously recorded. 



Belascaris mystax, Rud. 



Formerly grouped with an allied round- worm parasitic 

 in the dog, under the name of Ascaris canis. This species 

 was found in a local cat, and has not been recorded as yet 

 from this State. 



Toxascaris canis, Gm. 



Occurs in local dogs (Brisbane), but is apparently 

 unrecorded until now. 



Ascaris spiculigera, Rud. 



Numerous specimens were taken by me from the 

 oesophagus and stomach of. a cormorant, Phalacrocorax 

 sulcirostris , and a darter, Plotiis novcehollandice, shot on the 

 Burnett River, Eidsvold, by Dr. Bancroft. Ascaris, sp., 

 recorded by Krefft (1873, p. 213), from the latter host, 

 belongs to the same species. 



Some parasites which I have collected near Sydney 

 from the pelican, Pelecanus conspicillatus , are referred to 

 the same species. They are rather larger, but appear 

 to be specifically identical with the above.
