Davis Strait (Taylor). In several sets of Drummond's mosses 
no. 73, from the Rocky Mountains (distributed as Cafoscopium 
nigritum), there is no trace of this species. Dr. Mitten kindly 
sent a portion of the Davis Strait plant and indicates that Ho/m- 
gvenia rufescens (Dicks.) Lindb. has not yet been found in North 
America. In a letter dated April 21, 1896, he says: “I have 
looked through all my specimens of Orthothecium rufescens and 
find no trace of any North American examples. All Taylor sent 
me are in with O. chryseum, as are the 221 of Drummond in both 
my sets. I suppose I must have mistaken one of Taylor's to be 
the first named.”
