Professor James uses the *Mcadly parallel column" to indi- 

 cate the similarity of the second part of the paper by Professors 

 Coulter and Thompson above noted, to one published by him in 

 Volume iv. Journal of the Cincinnati Society of Natural History 

 in 1881, and complains that these authors have not referred to 

 it. It seems to the writer that this is considerable ado about a 

 small matter. On page 269 of the Indiana Report, Professor 

 James is referred to. Indeed, this is one of the subjects the dis- 

 cussion of which can only reach similar results. The main facts 

 are all in; only the numerical details can be modified. The Chest- 

 nut and many other species have long been known to inhabit all 



w 



three continents. It is not at all strange that similar passages 

 occur in the two articles, as Dr. Gray and several others have 

 discussed the subject at considerable length, and we cannot regard 

 the Implicated charge of plagiarism as sustained. — N. L. B.

After eighteen years of field experience Professor Greene 

 concludes that the calyx offers the best characters in defining 

 Polemonlaceous genera, Polenioninm filicimim is a new species 

 from the Pinos Altos Mts., placed next to P. flavtim recently
