the gecko, and of Oriental sore and kala-azar. Moreover it suggests the pos¬ 
sibility of an intestinal mode of infection in the latter disease. In the case of 
L. Henrici it appears as if the intestinal infection, still persisting in the lizard, 
has already given rise to a blood and tissue infection. 
Note on a cell-invading fungus. 
In some of the chamaeleons examined it was noted that a fungus (Text-fig. 2) 
was present, and in smears and.sections it was found that there was a definite 
invasion of the cells of the cloaca. The fungus occurs in the form of ovoid 
bodies embedded in the cytoplasm of the cells. Reproduction takes place by 
budding till the whole cell is invaded. In this process the nucleus becomes 
pushed aside and distorted and the cell eventually degenerates. Buds are

also formed, protruding into the cavity of the cloaca and when this has oc¬ 
curred growth into the lumen takes place with the formation of more elongate 
elements and finally filaments. No culture of this organism was attempted 
and nothing more of its life-history is known. The general characters are de¬ 
picted in the drawing shown in Text-fig. 2.

The protozoal organisms seen in the gut of these two lizards resembled 
one another and I have no reason to suppose that the forms common to these 
two lizards belong to different species. Those common to the two are Bodo 
lacertae, Grassi, or, as Alexeieff (1912) has renamed it, Prowazekella lacertae, 
Chilomastix sp., and Entamoeba sp. In addition to these three organisms, in
