pering gradually from the base, 10-20, thick, with conidia 
80-404 thick; sterigmata 6-15» long; conidia formed in 
chains, vertically arranged, not radially, spherical, rarely 
oval, 2-3» in diameter, at first hyaline, then gradually 
changing from yellow to green and finally to brown. 
This species has been reported in most cases of mycosis 
as being very frequently found in the respiratory tract of 
birds. It affects the eye, ear, and other parts of the body 
if they are accidentally injured or become diseased, as well 
as the lungs of men who feed birds in the manner previously 
mentioned. It occurs in cases of ceratomycosis, according to 
Leber (782) and Uhthoff ('83), and іп otomyeosis reported 
by Siebenmann ('89). Siebenmann considers A. nigrescens 
Robin as identical with A. fwmigatus. The species is very 
toxic for rabbits, guinea-pigs, birds, and monkeys. Dogs and 
cats, however, are not affected.

1909. 
Under the name of ‘‘nodosités juxta-articulaires,’’ Jean- 
selme has described a disease which occurs in Indo-China and 
Madagascar. Two of the cultures which were made closely 
resemble A. Tokelau in growth characters. The description, 
as given by Guéguen (’09), is that of a slow-growing Asper- 
gillus, producing meager fructifications of a greenish white 
eolor after a growth of three weeks on Raulin gelatin medium. 
No liquefaction of gelatin takes place before fourteen days, 
and only a slight liquefaction after a month. Its optimum 
growth temperature is 22-25°C., but no development takes 
place at 37°C. From these observations it is difficult to 
understand why an injection of spores of this fungus should 
prove fatal to rabbits and guinea-pigs.

This species has been reported as the green mould occur- 
ring frequently in the air sacs of birds, but more precise 
observations tend to show that these parasites are mostly 
A. fumigatus.
