Trypanosoma ingens, n. sp. 



nearer the posterior end than the anterior, and in our specimens has stained 

 a pale pink. 



The body substance is markedly granular behind the nucleus, while in 

 front the structure described as myonemes is particularly well marked. 



More minute measurements of one of these trypanosomes are as 

 follows : — 



microns. 



Posterior end to micronucleus 18 



From micronucleus to nucleus 4 



Nucleus : long diameter, 8 microns ; short diameter 4 



Nucleus to anterior end 40 



Free flagellum 17 



Total 83 



It is unnecessary in this preliminary note to go more fully into the 

 structure of this trypanosome, or to describe it at greater length. An 

 examination of the coloured drawings reproduced in Plate 7 will give a 

 more distinct idea of its appearance than any written description. 



The drawings were made by Lady Bruce, R.E.C. Figs. 1, 3, and 4 are 

 from reed-buck, fig. 2 from the ox. All are magnified 2000 and stained 

 Giemsa.
