HEXAGONA SUBTENUIS. In a personal letter received from 

 the Rev. Bresaclola, he claims that in my Synopsis of the genus Hexa- 

 gona, I have taken too broad a view of the species Hexagona tenuis, 

 that this species is confined to American territory, and that all the forms 

 from India and the East should be referred to other species. I readily 

 admit that Hexagona tenuis, in the sense in which I have taken it, is a

heterogeneous assembly of plants, and I suspect that with abundant 

 material other species may be differentiated. I have just received from 

 Col. K. R. Kirtikar, Bombay, nice specimens (Fig. 389) of what I 

 have published as Hexagona subtenuis, basing the name on a specimen 

 in Berkeley's herbarium. It differs from the type form of Hexagona 

 tenuis not only in the more rugulose upper surface, but in the color 

 of the pores which are distinctly yelloivish. I think this is a good 

 species, quite distinct from tenuis." We hope in time to get a clear 

 idea of the distribution and forms, but we can not without abundant 

 material. 



Correction. The last paragraph on page 460 was written by myself and 

 does not belong to Professor McGinty's article, as the printer has made it 

 appear. I assume no responsibility for Professor McGinty's opinions; in fact, 

 do not always endorse them, and I certainly would not wish to place upon him 

 any responsibility for my opinions.
