 Lye. Vol. YI. p. 3-1:4, suggesting that Say's description applies 

 rather to a young H. inflecta, than II. hirsuta, but anticipating 

 that " further researches will prove this to be a distinct 

 species." I now learn that II hispida L. inhabits some parts 

 of Kova Scotia, and also Canada East ; and Dr. Gould suggests 

 — as indeed seems highly probable — that R. porcina is identi- 

 cal with it.
