forms was not seen. The edge carrying the undulating membrane 
has a wavy outline. The width of the body at the level of the 
nucleus is less than just anterior or just posterior to it. 
The narrow form (Plate XXVIII, fig. 40) was seen in one case to 
have a blue line running from blepharoplast spirally to the posterior 
extremity, and the undulating membrane was continued for a short 
distance posteriorly as a ridge beyond the blepharoplast. The 
medium form is seen in Plate XXVIII, fig. 41. 
All the forms have clear spaces around the nucleus and 
blepharoplast.

V. The remaining trypanosome to be described is a long narrow 
form, with a narrow nucleus, and a large blepharoplast (Plate XXVI.
