"TN their " Fungi of Ceylon " Berkelej^ and Broome 

 -L enumerated 44 species of Ustilaginece and Uredinece. 

 Subsequent examinations bj^ various mycologists have reduced 

 that number to 36. The present list, which contains 130 

 species,' does not make any pretence to completeness, but 

 merely records those which have been collected at Peradeniya 

 and, practically by chance, during visits to different parts of 

 the planting districts. Systematic collecting would be certain 

 to increase this number considerably, especially in the hotter 

 and drier districts, in which" very little has yet been done. It 

 may be noted that those of the older records which have not 

 been confirmed relate chiefly to species in those districts. 



Attention may be specially directed to the notes on Ustilago 

 spermoidea, Thecaphora inquinans, Th. Berkleyana, Puccinia 

 congesta, P. fremandrce, Uredo gossypii, and Ravenelia maero- 

 cystis.
