plast wliich stained deep pink almost black and jiist anterior lo it 
is the equally large granular nucléus; stretcdiing from the ble- 
pharoplast along the margin of the cell and terminating at the 
pointed extremity is seen the pink staining contractile band. d'his 
end of the parasite contained many deeplv stained chromatoid 
granules especially grouped round the nucléus. The posterior 
non-motile end is seen to be drawn out to a considérable length 
ending bluntly ; it stained a délicate pink and suggested a loose 
ectoplasmic sheath. l'igure 2 depicts a very similar parasite but 
with a much more pointed anterior end and a shorter posterio'* 
extremitv. Figure 3 is a stout form about to divide, both the 
l^lepharoplast and the nucléus are much elongated and figure 4 
represents a parasite undergoing the process of simple longitud¬ 
inal fission, many of these parasites also exhibited ail the stag¬ 
es of unecpial division. Figure 5 is another large form which 
shew's the bent snout-like anterior end so characteristic of the 
parasite, hdgure 6 is one of the tadpole-shaped forms, the anter¬ 
ior end is here shewn pointing downwards while the blepharo- 
plast lies at the extreme end of the posterior extremity. These 
parasites are very active wriggling along with the drawn out end
