THE HiEMOPLAGELLATES. 



285 



It is uncertain whether the Flagellate organism described by Labbe (29) 

 from the medicinal leech (Hirudo), which had probably sucked the blood 

 of a horse or ass, should be placed here or not. This parasite (fig. 39), 

 to which Labbe gave the name of Trypanoraonas danile wskyi,' 

 was elongated almost filiform (15-20 /i by 1 /i), with apparently along, thin, 

 more or less coiled flagellum at either end. It also possessed a delicate un- 

 dulating membrane. Labbe considered one of the flagella to be a very 

 attenuated prolongation of the body and membrane, on the analogy of the 

 spindle-like forms figured by Danilewsky (cf. fig. 16 G of Hanna's Trypano- 

 some from Indian pigeons). In that case, the parasite would really be a 

 spirochajtiform Trypanosoma, but the figures, so far as they go, do not 

 convey that impression. Re-investigation of it is necessary in order to 

 settle its position.

 well developed, however, especially in T. grobbeni. The 



^ Even if this form is found to agree generically with Trypanoplasma, 

 Labbe's name Trypanomonas could not be used, since this designation 

 was originally employed by Danilewsky for the young forms of a Try- 

 panosoma, with which, therefore, it is synonymous.
