vised synopses of the genera, the latter made by one of large experi- 
ence in the study of these minute parasites and their allies. In 
describing the new genus Oophthora, Aurivillius reviewed the litera- 
ture of the whole family which he summed up in a generic synopsis 
of the family of some weight and importance, and some of which 
I shall accept. The table is given in Scandinayian and Latin 
and I quote that given in the latter language as being the one more 
easily read. Aurivillius follows Thomson (1878) in ranking the 
group as a subfamily but bases his synopsis on Foerster’s Ueber- 
sicht, very properly not following him blindly, however. The 
Latin portion of the table is quoted at once :
