NoTK. — Owing to the author's absence in the field when his article on 
the 'Mammals of Mt. Mazama' was going through the press, he had no 
opportunity to read the proof. As a result, a few errors have crept in and 
a few intended changes in nomenclature were not made. 
The following corrections should be made: 
Page 210, line 2 from bottom, after alpinus add faliginusus. 
Page 216, line 19, for Sciuropterns alphms (Richardson), read Scluroptenis 
(il.pinus fuUg'mosus Rhoads. 
Pages 215, 216 (and elsewhere), begin the specific names colutnbianus, 
ataericana, alphius, kl(iin((tJiemis, and califormcns with small letters instead 
of capitals. 
Page 216, line 5 from bottom, add : Several additional specimens have 
been sent me by .Mr. B. L. Cunningham, of Fort Klamath. 
Page 217, line 11, for Bachman read Allen. 
Page 229, line 12, for Vespcrli/io yumanensis, H. Allen, read Mijotis 
II amanensis saturatm Miller. 
Page 229, line 17, for VespertUio read Myotis. 
Page 229, lines 5 and 6 from bottom, for PJptesicus read VespertUio. 
Page 229 (and elsewhere), change the generic name VespertUio, wher- 
ever it occurs, to Myotis. 
Throughout the article strike out the comma between the specific name 
and the authority.
