I have some large flukes (family Monostomiiln-) Im-Ioii-hii: 

 to this genus, taken from the pharynx of a black swan in 

 Victoria, by Mr. A. S. Le Souef. 



Krabbe 1 in 18G9 described a cestode Taenia liophallos 

 ( = Hijme>iol< pis liojtlnillos, Krabbe) from Leuckart's collec- 

 tion, taken from this host. He also" gives a very brief 

 account of Taenia micvuuevistrota, \\>dl." ( = Hipnenolepis 

 micrmirvist rota, Wedl.) described from material collected 

 in Hungary. Linstow 4 recorded both of these tapeworms 

 under this host. Fuhrmanir' does not place either of these 

 under this bird, but under C ugnu s tnusicus, Bechst. Ransom" 

 lists the two under Olor cyanus, Linn. Sharpe 7 regards 

 both C. miisicus and O. cygnus as synonyms of Cygnus 



Besides the above cestodes, a nematode, Heterakis 

 rcsifitlaris, Kud. ( = H. papillosa, Bloch) has been recorded 

 by Schneider 8 as being taken from the caecum of Chenopsis 

 atrata in the Zoological Gardens, Berlin. He mentioned 

 that the bird had lived a long time in the Gardens and 

 consequently the occurrence of this parasite in Australia 

 did not necessarily follow. In 1906, Linstow 9 ga ve an account 

 of another nematode Heterakis circiimvallata, Linst., from 

 this bird (Konigsberg Museum) but no locality is given. 



Both Sharpe 7 and Matthews 10 give the range of this bird 

 as "Australia generally and Tasmania." It has been
