Berestnefi described several forms in owls, ravens, and magpies, but noted 

 that they were in leucocytes; and in the same year came Schaudinn's paper 

 on the development of Leucocytozoon ziemanni, which is given in detail later on. 

 The Sergents, in studying the parasite in the little owl in Algeria, supported 

 Schaudinn. In 1905 Laveran and Lucet studied Theobald Smith's parasite, 

 and concluded that it was enclosed in a leucocyte. In 1906 Neave described 

 a parasite in Numidia ptilorhynca; and in 1907 Sambon and Seligmann 

 described one in Lagopus scoticus (the red grouse) ; and Dutton, Todd, and 

 Tobey another in Astuvinula monogvamniica (the Congo grey hawk); and 

 lastly Sambon has reviewed the whole genus in a singularly able manner, and 

 has described species from the capercailzie {Tetrao urogallus) and the pheasant 

 [Phasianus colchicus). Important work has been done by Fantham, who 

 demonstrated a schizogony in L. lovati Sambon and Seligmann, 1907. E. H. 

 Ross has suggested that Kurloff's bodies may be Leucocytozoa, and may 

 produce spirochsete-like organisms.

ziemanni Liihe, 1906. L. danilewskyi is found as a parasite in the haematoblasts 

 (or, according to other authors, in the leucocytes) of the little owl, Glaucidium 

 noctucB {A thene noctuce Retz) , and the wood-owl, Syrnicum aluco L. 



The history of the life-cycle, according to Schaudinn, may be begun with
