40 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Leucocytozoon from Chinese Partridge.* — M. Leger and C. Mathis 

 describe Leucocytozoon mesnili sp. n., an intracellular parasite from the 

 blood of Franco/ 7 n m sinensis. The macrogametes and microgametes 

 are described. There is some resemblance to Hsemamocba majoris from 

 the tit, and to a Leucocytozoon from the African francolin. 



New Parasitic Amoeba in Man.| — M. Koidzumi describes Entamoeba 

 nipponica sp. n., found in the intestine of Japanese in advanced cases of 

 amoebic dysentery. He compares it with other species and discusses 

 (1) the binary fission ; (2) the schizogony and development of mero- 

 zoites ; and (3) the encystation and chromidium formation. 



New Amoeba in Man. J — M. Elmassian describes Entamoeba minuta 

 sp. n., associated with E. coli, in a patient suffering from dysentery. It 

 shows asexual mitotic division into four, and autogamy followed by 

 sporulation. 



Malaria in Birds of Greece. § — Jean P. Cardamatis has made a 

 study of Danilewsky's Halter idiuni, which he has found in fifty-three 

 species of birds in Greece. He examined 936 specimens and found the 

 parasite in 25 '64 p.c. The transmission is effected by mosquitos. 



Haemoprotozoa in Birds of New South Wales.|| — J. Burton Cleland 

 and T. Harvey Johnston deal with Halteridivm ptilotis sp. n., from 

 Ptilotis chrysops ; H. philemon sp. n., from Philemon corniciihitus ; 

 H. geocichlse sp. n., from the ground thrush, Geocichla lunulata ; 

 H. meliornis from the honey-eater, Jleliomis novae-hollandise. They 

 call attention to the very striking resemblance between spermatozoa of 

 the honey-eaters and spirochaete-trypanosomes. 



Symmetry of Embryo Acinetse.f — B. Collin discusses the sym- 

 metry and orientation of the embryos of Ghoanophrya, ToJcophrya, 

 Acineta, and other forms. There is a constant morphological axis 

 perpendicular to the plane of vibratile cilia. This axis determines a 

 superior or apical pole, corresponding to the oral pole of a discotrichous 

 Infusorian, and very often bearing an oblique row of long cilia (rudi- 

 mentary adoral zone). The inferior or basal pole shows granular 

 secretions, and sometimes a sucker ; this is the point of fixation and of 

 stalk-formation, if there is a stalk. It corresponds to the aboral pole, 

 carrying the " scopula " in the ancestral Vorticellids. 



Hypertrophied Acinetae.** — B. Collin has studied the modifications 

 induced in Tokophrya and Acineta by over-feeding. These organisms 

 appear to be very suitable subjects for such experimentation, and some 

 interesting phenomena of degenerative growth are described.
