1 Siirnium, nebulosum, var. stirhrii, Ridgwav (Mexican Barred Owl). Ilah. Mirador, 

 Me.xii'o. C'liAlt. Atliill. (9. 43,131, Mirador, near Vera Cruz, Mexico, "pine region"; Dr. 0. 

 Sartorius). In general n])pearaiice like nebulosum, but the brown very much darker, and less 

 reddish, — that of the markings below very nearly black ; the pattern, however, precisely the 

 .same, and there is about the same proportion between the light and the <lark bars as is seen in the 

 average of nebu/asuin. Tint face is ]>laiu dirty white without the brown bar.9 or semicircles, — a 

 constant and conspicuous I'eutine in nebulosum. There is the same number of spots on the primaries, 

 and of bands on the tail, as in nebulosum. The white l>eiieuth is without any ochraeeous tinge ; 

 the primary coverts are plain dark brown. Witig-foi-nnda : 4 — 3 = ."> ; 1 intermediate between 

 8 and i). Wing, 14.80 ; tail, D.On ; eubin^n, l.O'i ; tarsus, 2.'20 ; middle toe, 1.60. This race of the 

 ,S'. iiebulosuiii |ircsents very iippreciiible dilfe- wics from the bird of the United States. A.s stated 

 above, the brown is nnieh darker ami less ■edijisli, while thi' f n e is whidly destitute of the con- 

 centric du.sky rings .seen in nrhulosum )>riilK' •. To Dr. Charles .Sartoriu.s, who, by the pn'sentatiou 

 to the .Sudtlisouian Institution of numi'rousel.-giintly pivpared specimens, has added so much to our 

 knowledge of th<' birds of the vicinity of M'' idor, I take great pli'asure in dedicating this new form.
