514 Arthur : New species of Uredineae 



which should read Cerotelium. The derivation is from *^ooc, wax, 

 and teliam (from ri/oc). 



There are also errors in the recent paper on " North American 



species of Peridermiam" by Arthur and Kern, published in the 

 August number of this journal, which might be pointed out here. 

 The host of Pcridermiitm Holwayi (Joe. cit. page 431) proves to be 

 Abies lasiocarpa (Hook.) Nutt This was ascertained by Professor 

 Holway, who visited the type locality in August of this year in 

 company with Mr. F. K. Butters, who knows the trees of the 

 region well, and found that there can be no question regarding the 

 error in the original determination. Abies lasiocarpa and Pseudo- 

 tsuga mucronata have a similarity of appearance which makes it 

 quite easy to mistake one for the other. It was found, however, 

 that while the Abies is abundant in the type locality, the Pseudo- 

 tsuga is entirely absent, although it does occur on slopes of the 

 same mountains at a lower altitude. As no Feridermium has yet 

 been correctly reported on Psendotsuga, the lines referring to this 

 host on page 41 1 should be cancelled, and the species with its cor- 

 rected host transferred to the top of the next page to follow P. 

 pseiido-balsameum. In the first column of the table, on page 405, 

 Abies should be substituted for Pseudotsug-a. Besides this, th 



is an erroneous citation of a host under Petidermium Cerebrum- 

 On page 424 the three lines referring to Finns ponderosa should 

 be stricken out.
