the intestine, the adult form being found in its lumen — not 

 previously reported from cattle in our State ; Stephanurus 

 dentatus (Sclerostomum pinguicolum), from the renal tract 

 of a pig (N.S.W.); Ankylostoma (Uncinaria) trigono- 

 cephalum, from a dog (N.S.W.), a parasite producing effects 

 similar to those caused in human beings by its ally, A. 

 duodenale, which was unfortunately becoming rather com- 

 mon in Queensland. He also exhibited two ticks belonging 

 to species which were responsible for carrying the organisms 

 of diseases, viz., Margaropus annulatus, the " Queensland 

 cattle tick," which transmitted Babesia (Piroplasma) 

 bigemina producing Piroplasmosis (tick-fever) in cattle 

 in Queensland and occasionally in New South Wales and 

 West Australia ; and Argas americana, the carrier of 

 Spirochceta anserina (S. gallinarum), the organism of fowl

 with a big series of lantern slides copied from Haeckel's 

 beautiful plates. The lower forms of vegetable life were

 and other members of the same group, the disc-shaped
