Johnston, Internal Parasites: 



r Emu 



L I St Oct. 



S. J. Johnston (P. L. S., N.S.W.) ; Dr. Cleland and myself 

 (P. R. S., N.S.W. ; Tr. R. S., South Aust. ; P. L. S., N.S.W. : 

 P. R. S., Queensland ; Rec. Austr. Museum ; Ann. Rep. Towns- 

 ville Troi)ical Institute) : and Plimmer (Journ. Roy. Micr. Soc. 

 1912). 



The main abbreviations used are — J . & C, C. & J . ior Cleland and 

 Johnston, and J., T. H. J., or Jnstn. for Johnston. Many of the 

 records are now made for the first time. 



Ornithologists are asked to assist in the collection of both 

 internal and external parasites. Spirit is the best of the common 

 preservatives for external parasites and for roundworms, while 

 formalin (about 3 per cent.) is a good all-round preservative for 

 tapeworms and flukes. Blood parasites are examined in blood- 

 smear preparations, a small drop of blood being drawn across 

 a glass micro-slide with a needle to form a very thin smear, the 

 slide being then labelled with host's name and locality, and the 

 smear being allowed to dry. 



Tapeworms are found in the intestine ; flukes in the intestine 

 mainly, but also in other parts, such as the body cavity, &c. ; 

 hook-headed worms in the intestine, or — ^in their larval form- 

 under the skin as small whitish nodules ; while roundworms may 

 be met with in any part of the digestive canal, in the body cavity 

 or mesenteries, or under the skin. 



* This record is based upon material collected near Sydney by Mr. L. 

 Harrison. His description of the parasite satisfies me that the worm was 

 Rictularia, and most probably R. shipleyi- Unfortunately, the nematodes 

 have been mislaid, and I am therefore, at present, unable to confirm the 

 specific identity.
