as I can personally consult them at present—contain any decisive 
statement from which one or the other of the two Hong-Kong species 
mentioned above might be recognised. In 1897. GlARD and BlLLE" 
apparently ignorant of the existence of the Di stoma pancreatine 
described a Distoma coelomaticum which the latter author had found 
plentifully in the pancreas of an ox killed at the slaughter-house of 
Cao-Ban g (1 onkin) ; there had at first been some mistake as to the 
habitat ol the parasite which led to the denomination coelomaticuw 
but this mistake was corrected afterwards upon a suggestion of 
Railliet. The details given in GlARD and BILLET'S description 
are sufficient to show that Distoma coelom at icum, also structural!) 
resembles Dicrocoelium Invocation and Distoma paucreaticum , but 
theie is again no statement which would be indicative of one of our 
two species in contradistinction from the other. 
The latest description of Distoma pane real icum is given t 
AILLIE1 and Marotel in 1898. The specimens upon which the 
I apei is based were collected by Dr. GOMY, a French veterinai
