trypanosome may divide by equal longitudinal fission (fig. 37, C, D), 

 but more commonly multiple fission occurs (fig. 37, G, H), and is 

 unequal. Rosette forms are produced, in which the parent form can 

 be recognized by its long flagellum (fig. 37, H) and attached to it are

daughter individuals, smaller in size, from which flagella are growing. 

 Minchin and j. D. Thomson (1912) find that the daughter forms may 

 be set free sometimes with a crithidia-like facies (fig. 37, I), the 

 blepharoplast being anterior but near to the nucleus. The daughter
