Parasitic Worms 
unsightly. It does not infect man though it is closely allied to a similar 
human parasite. Earlier investigations had been carried out by the 
Australian Authorities at Sydney and Melbourne and full reports were 
published by Cleland and Johnston (1910) and Gilruth and Sweet 
(1911). The life-history of the parasite, however, is still a mystery, 
and until that is known little can be done towards eradicating the 
disease. 
Of the other diseases of domesticated animals probably most work 
has been done on Trichinelliasis in pigs and Sclerostomiasis in horses, 
but not much of it has been of an outstanding character. One of the 
most interesting new facts disclosed is that the faeces of swine infected 
with Tricliinella are infective for other animals. This statement was 
made by Ressling (1910) and confirmed by Raebiger (1911). Such 
a fact introduces an anomaly into the life-history of this parasite, which 
had not hitherto been suspected, and it is of great importance from an 
epidemiological point of view as it largely increases the chances of 
infection. 
It may be of some interest to give a brief account of the new worm 
parasites which have been added to the already long list of those infecting 
man. Within the period under consideration 11 new forms have been 
discovered. Many more have been described as new but have been 
found later not to be so. Of the total number four are flukes, four 
tape-worms and three Nematodes. The new flukes are Fcisciolopsis 
fulleborni, F. goddardi, Ecliinostomum iloccinum and E. malayanum. 
With regard to the first two there is considerable controversy as to 
whether they are really distinct from the better known species 
Fcisciolopsis buski, and the question must still be regarded as unsettled. 
There seem to be well-marked differences between these forms at the 
time of collecting but beyond that we have no structural details. 
The new tape-worms are Taenia bremneri, Dibothriocephalus parvus, 
Diplogonoporus brauni and Braunia jcissyensis. Of these the last is the 
most interesting. It is the first representative of the Liguline tape¬ 
worms ever found in man, and is characterised by being unsegmented 
externally. The new Nematodes are Lagochilascaris minor, Agamofilaria 
georgiana and Physaloptera mordens, of which the last mentioned is 
probably the most interesting.
