 Oil the Abilities of Herpetomonas subulata *, and the Plvjlogeny of 



the Tri/pcmosomes. By Louis Legeb. 

 Thb structure of Herpetomonas subulata points to its extremely 

 close affinity with certain species of Crithidia previously described 

 by me. To Crithidia minuta of Tabunus tergestinus, Egg., espe- 

 cially, the resemblance of the young gregarine and monad forms is 

 such that it is impossible to distinguish these two Flagellata iu 

 these stages. 



* [This parasite is described by M. Leger in the number of the Comptes 

 Ilend. Ilebd. des ISeances de la Soc. de Biologic (Dec. 30, 1904, pp. 613- 

 615) from Avhich the present extract is taken. lie states (loc. cit. p. ()13) 

 that he met with it in the alimentary canal of Tabamis (/laucopis, Mg. 

 (a species of horse-fly which occurs in Great Britain), in the south of 

 France. According to M. L6ger.it is not common, and lie found it only 

 four times in sixty specimens of Tabanvs and llamutopota collected in 

 autumn upon cattle and horses, — Tbansl.]
