This tiny parasite was found in considerable numbers 

 infos i ing the mesentery of a local lien. Most members of the 

 Acarida {Acarina) lead a free or ectoparasite existence, 

 while a few penetrate into the skin, e.g. Demodex,S ircoptes % 

 Psoroptes, etc. Sarcoptes (Cnemidocoptes)mutans, Kobin, 

 the itch mite which produces the disease known as "scaly 

 leg" of poultry, and which occurs in this State, 1 comes

 tissues. Examples of the latter group are Cijtodites, 

 Falciger (in certain stages) and others, some of which

Mr. E. A. Le Souef of the Zoological Gardens, Perth,

 Western Australian turkeys and fowls. 



Bradshaw 2 regards the disease known locally as "black- 

 head," as the same as that known under this name in the 

 United States, and produced by a protozoan, Amoeba 

 (Entamoeba) mclntijridis, Th. Smith. Films taken from 

 the inflamed areas in the intestine and liver and examined 

 by Dr. F. Tidswell, Dr. Cleland, and myself show the 

 presence of very numerous organisms which are probably
