I. HISTORY AND ORIGIN OF THE PARASITE 
THE external features of this Trematode have been described by Mr. H. F. 
Conyngham.' The history of the parasite is given in the following account 
kindly furnished me by Dr. J. W. W. Stephens, to whom Dr. Watson 
communicated it : — 
' The patient was a Pagan who had come from Adainawa, German West 
Africa — one of a gang of freed slaves brought to the Resident of Zola, 
Northern Nigeria, nearly all of whom were in a terrible condition due to 
starvation. 
He made a certain amount of progress at first, but did not improve as 
the others, and had constant diarrhoea. The stools were watery and of a 
bilious colour, no blood or mucous in the same. He was taken into the 
hospital but died the same night, and on inspecting the stools passed during 
the night numerous reddish-yellow, translucent, gelatinous, oval bodies were 
found. 
Post-Mortem. — The lungs and heart were normal. Liver normal. The 
spleen small, hard, and black. The stomach contained some food, and on 
opening the small intestine the duodenum and upper part of the jejunum 
were found full of the oval bodies, none of them adherent, although they 
were alive. The mucous membrane was reddish, but no haemorrhages or 
petechiae were apparent. The rest of the bowel was normal, a few of the 
oval bodies being found loose in the large intestine. The kidneys were 
normal. The oval bodies have shrunken considerably, and are only about a 
third of the normal size. 
These Pagans appear to be extremely fond of raw meat, and eat fowls 
raw.'
