TELOSPORIDIA 



mononucleate d merozoites, the whole process taking some twenty-six or more 

 days. The minute merozoites now enter the red corpuscles and grow into 

 typical Halteridia. It appears that there are no trypanosome stages, and, 

 indeed, the only form of that nature met with was Trypanosoma avium Novy 

 and McNeal. 



This is quite a different history from that of Schaudinn for H. noctucB, but 

 it must be observed that it is incomplete, and, therefore, deductions cannot 

 safely be drawn from it. 



Other Species. — A large number of species are described by Celliand Sanf elice, 

 Novy and McNeal, and others, which have been found in birds as well as in 

 some reptiles.

 (After Sambon.) 



Sambon has described, under the name of Hcsmoproteus mansoni (Fig. 176), 

 a new species found in the red grouse [Lagopus scoticus), the gametocytes of 

 which are not closely adherent to the nucleus of the erythrocyte, as is usually 

 the case, and sporogony takes place in a parasitic fly of the grouse {Ornithomyia 

 lagopodis), in the stomach of which ookinetes were found. 



Anschiitz has described a schizogony of H. oryzivorcB taking place in the 

 circulating blood of Padda oryzivora.
