 (Mirador) var. sai-torii.^ 



Colors tawny-brown and bright fulvous. Face without darker con- 

 centric rings (?). Wing, 12.50, 12.75; tail, 7.30, 8.50. Hab. Gua- 

 teni.ila .......... vm: fill v esc ens .^ 



3. S. occidentale. Lower parts transversely barred. Head and neck 

 with roundish spots. Wing, 12.00-13.10; tail, 9.00. Hub. Southern 

 California (Fort Tejon, X.\ntcs) and Arizona (Tucson, Nov. 7, Bexdire). 



' Symium nebulosum, var. sarlorii, Ridgway (Me.xican Barred Owl). Hab. Miiador, 

 Me.\ico. Char. Adall (9, 43,131, Mirador, near Vera Cruz, Mexico, "pine region"; Dr. C. 

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

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

 same, and there is about the same proportion between the light and the dark bars as is seen in the 

 average of nebulosum. The face is plain dirty white w^ithout the brown bars or semicircles, — a 

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

 and of bands on the tail, as in nebulosum. The white beneath is without any ochraceous tinge ; 

 the primary coverts are plain dark brown. AVing-formida : 4 — 3 = 5; 1 intermediate betw'een 

 8 and 9. Wing, 14.80 ; tail, 9.00 ; eulmen, 1.05 ; tarsus, 2.20 ; middle toe, 1.60. This race of the 

 S. nebulosum presents very appreciable differences from the bird of the United States. As stated 

 above, the brown is much daiker and less reddish, while the face is wholly destitute of the con- 

 centric dusky rings seen in nebulosum proper. To Dr. Charles Sartorius, who, by the presentation 

 to the Smitlisonian Institution of numerous elegantly prepared specimens, has added so much to our 

 knowledge of the birds of the vicinity of Mirador, I take gi'eat pleasure in dedicating this new form. 



^ Syrnium nebulosum, va.r. fulvcscens. Symium fuliicsecns, Salvix, P. Z. S. 1S68, 58. Ch.\r. 

 General appearance of var. nebulosum, but smaller and much more ochraceous. Ground-color of the 

 plumage ochraceous, inclining to a deep fulvous tint on the upper parts, but paler below. Feathers 

 of the upper surface tipped with dark umber-brown, and sometimes with an additional bar about 

 the middle of the feather. The fulvous bars much exposed, so as to exceed the brown in amount. 

 Face grayish -white, tinged outwardly with ochraceous. Beneath with the markings of nebulosum 

 on a deep and uniform ochraceous ground. Wing. 12.75 ; tail, 8.50 ; eulmen, .95 ; tarsus, 2.45 ; 

 middle toe, 1.20 (Coll. Bost. Soc, No. 367, Guatemala ; Van Patten).
