the spirochaete as Spirillum sp.; Dodd, as spirocliaotes, 

 and myself as »S. ansevina (S. gulliu'wum). There are 

 some other references to fowl tick-fever (e.g. in Agr. Gaz. 

 N.S.Wales), but as the organism is not referred to in any 

 way I have omitted them. The transmitter of the organism 

 in Australia is the so-called "fowl-tick" Argas persicus, 

 Oken, (syns. A. amevicana, Packard, A. niiniul hs, Koch), 

 which is reported as being able to inflict serious injuries on 

 human beings ; ' in certain parts of the world, e.g. Persia. 

 This tick is fairly common in New South Wales, but seems 

 to restrict its action to poultry. Blanchard 2 regards A. 

 miniutiis, fvoch (syn. A. americaim) as being quite distinct 

 from, though closely allied to, Argas persicus. 



Treniatoda -.—Prosthogonimus ovatus, Linst. (formerly con- 

 fused with Distomum ovatum, Rud.) 

 Spencer 5 referred to the presence of small flukes in eggs 

 from Victorian fowls. Though he does not refer to the 

 helminth by name, yet his description evidently refers 

 to the above named parasite. This usually infests the bursa 

 of Kabricins of yu'.mtr birds, and has been occasionally found 

 in the oviduct, and even in the eggs of mature fowls in 

 other parts of the world. 4

 Linn. Soc. N.S. Wales, xxxiv, 1909, p. 599. (N.S.W.) 

 This delicate tapeworm does not seem to have been pre- 

 viously recognised in Australia. The same remark applies 

 equally to the following species.
