clinically resembling thrush. A microscopic examination of 
substances taken from the pharynx revealed the presence of 
ovoid cells 8-9 X 5-64, united in groups of eight or ten. 
Budding took place only at the extremities of the cells. In 
culture asci with four globose ascospores, 2» in diameter, were 
formed. There was no liquefaction of gelatin and no film 
formation in liquid nutrient solutions. Saccharose present 
in quantities less than 10 per cent in nutrient solutions was 
completely changed to alcohol.

This — was found by Vuillemin and Legrain in a tumor 
of the inferior maxillary region of a man. It appears in the 
form of oval or elliptical cells 2-10 X 3-4u, with a membrane 
covered with isolated granulations or striations disposed 
in regular lines. The cells form one, rarely two, buds and 
enclose fat bodies of a red color. Chlamydospores are some- 
times present in eultures. In liquid media the fungus does not 
produce a film but forms a red sediment. It does not liquefy 
gelatin. Two to four spherical or elliptical spores appear 
in each ascus. This yeast is slightly pathogenie for the rab- 
bit when inoculated intraperitoneally.

This species was discovered by Remack and Robin, and 
later studied by Casagrandi and Wilhelmi. It is normally 
present in the stomach and intestines of the rabbit, and of 
certain birds and reptiles. 
The cells of this fungus are very large, 6-16 X 2-4и, oval 
or more or less rectangular, and united in groups of two or 
three. Budding takes place at the two poles of the cells. The 
optimum growth temperature is 35-37°C. No film is observed 
in liquid media. Ascospores, one to four in each ascus, are 
present only in the excrement of the rabbit. The spores are 
oval with a double membrane. At the beginning of germina- 
tion, the exospore breaks at one end or at the side of the
