The data for this table were obtained from the distribution of the various species given by De Toni (1889-1907); from the 
lists of Collins for New England (1900), Jamaica (1g0r), and Vancouver Island (1913), of Hauck for Porto Rico (1888 a), of Bér- 
gesen for the Virgin Islands (Danish West Indies) (1913-1919), of Setchelland Gardner for northwestern America (1903), and of 
Saunders for Alaska (rgor); and from information kindly furnished by Mr. Frank S. Collins and Dr. Marshall A. Howe.
