Dr. Wilson has described only the sexual forms of Ji'. thunbergii 

 Wilson from Japan, the viviparous forms of which are not known yet; 

 and it is possible that E. plniformosantis n. sp. may be a synonym of 

 Wilson's species. 



7i'. af/ills (Kalt.), recorded from South China hy Prof. v. d. Goot, 

 has never been collected in Formosa. 



In my opinion E. tnbereulostemmata (Theob.) from Africa might be 

 a synonym of E. rilej/i Williams from North America.
