Cyst-formation, development, and life-history of Herpetomonas muscce-

(particularly complex in this form) described, id. (278).

F. Group Relationships ; Classificatory Changes. 
Chlamydomyxa is to be placed in the Mycetozoa, being probably allied 
to the Mycetozoidea {Euplasmodidce), Penard (260). 
PoPOFSKY (270) considerably amplifies the classification of the Acantho- 
metrea^ introducing especially several new families and sub-genera. 
Relationship of the Actinomyxidia to the Myxosporidia, Caullery & 
Mesnil (65) & Leger (183). 
Calkins (58) creates the family Cytoryctidce for Cytoryctes, Caryoryctes 
n. g., and Lymphosporidium, which he places in the sub-order Micro- 
sporidia, though with reservations. [The Recorder fails to see much 
resemblance between these forms and a typical Microsporidian. Consider- 
ing, for one thing, the very different character of the nucleus (of the 
"distributed" type in his family), it seems much better to leave these 
forms in the Serosporidia, where, indeed, Lymphosporidium has been 
hitherto placed.] 
On the affinities of Trypanoplasma and Trypanosoma and the derivation 
of the latter, Lieger (181). 
Affinities of Trypanosomes with the flagellum morphologically anterior 
(type T. noctace, after Schaudinn) with Herpetomonads, Leger (187). 
The Astomata so-called do not represent a natural group; the Opalinoe 
are very different from the other members and should be placed in a 
distinct family, Leger & Duboscq (193). 
Basing his views on a comparative study of the fixative apparatus of 
Vorticellidce, Faure (100) derives the Discotricha (or Peritricha) directly 
from the Holotricha, through forms like Scyphidia. and Hemispeira, which 
^ are to be regarded as primitive. This has more in its favour than a 
Hypotrichous origin through the XJrceolaridoe.

Piroplasma hominis is conveyed by a tick, Bermacentor reticulatus, 
Wilson & Crowning (360). 
Transmission of Typanosoma noctuoe and Spirocha^ta ziemanni by the 
gnat Culex, which is a true alternate host ; hereditary infection of the same, 
Schaudinn (301). 
After his investigations on leeches as the alternate hosts of piscine 
Trypanosomes and Haemogregarines, Brumpt (49) is fully convinced that 
the Glossinoe are true alternate hosts of mammalian Trypanosomes. 
White rats found naturally infected with T. lewisi ; infection undoubtedly 
conveyed by fleas or lice, Laveran & Mesnil (175). 
Probably a mosquito transmits Trypanosoma equinum from the native 
host {Hydrochoerus) to domestic animals, at the hour of drinking, Elmassian 
& MiGONE (92).
