quite distinct from the fusiform group, since in all stages — : 

 from young forms right up to large gametocytes — the parasite 

 and its host-cell retain the rounded form. Apparently Mathis 

 and Leger's form, L. marchouxi, from Turtur humilis 

 (lOc), also agrees with this type, for in this case the authors 

 find the host-cell intact, the whole appearance of parasite 

 and leucocyte being, so far as can be judged from the account, 

 similar to that of L. f rin gill i nar um.
