Pipilo fuscus buUatus, new subspecies 

 Oregon Brown Towhee 

 Ti/pe. — Male; no. 46578, Mus. Vert. Zool.; Eagle Point, Jackson County, 

 Oregon; January 9, 1926,- collected by William E. Sherwood. 



Dis'tinguishing character's. — At the maximum size of the races of 

 Pipilo fuscus; the bill, in particular, long and heavy. Coloration, 

 tending to slate gray, a shade that becomes accentuated in worn spring 

 plumage ; sides and flanks more heavilj^ and extensively saturated with 

 brownish slate than in carolae. 



Range.- — Known only from the Upper Sonoran valleys of Josephine 

 and Jackson counties, southwestern Oregon. The habitat of hullatus 

 is apparently entirely separated by mountainous territory from the 

 northern boundary of carolae, at the upper margin of the Sacramento 

 Valley. 



Remarks.— ^■pecim.ens from Kerby, much nearer the coast than 

 the other localities represented, are slightly more tinged with brown, 

 though at that they are more grayish than carolae. (For comment 

 upon the Kerby specimens, see Grinnell, 1912, p. 199.) Birds from 

 Ashland, Eagle Point, and Trail exhibit the extreme of slatiness seen 

 in the brown towhees of the Pacific coast. 



In nomenclatural treatment of the Pacific coast forms of the brown 

 towhee we are following the procedure advocated by Oberholser (1919, 

 p. 210), who asserts the existence of intergradation between the fuscus 

 and crissalis groups, usually heretofore regarded as specifically dis- 

 tinct. His claim of intergradation between senicula of northern Lower 

 California, and alhigula^ of the Cape San Lucas region, through the 

 subspecies aripolius (Oberholser, loc. cit.) of middle Low«r California, 

 is corroborated in statements by Thayer and Bangs (1907, p. 140). 



The Pacific coast races of the brown towhee now stand as follows, 

 listing them from north to south. Reference should be made to the 

 accompanying map for approximate geographic allocation. 



1. Pipilo fuscus hullatus Grinnell and Swarth. Oregon Brown 

 Towhee. 



2. Pipilo fuscus carolae McGregor. Sacramento Brown Towhee. 



3. Pipilo fuscus petulans Grinnell and Swarth. San Francisco 

 Brown Towhee. 



4. Pipilo fuscus crissalis (Vigors). California Brown Towhee. 



5. Pipilo fuscus senicula Anthony. Anthony Brown Towhee. 



6. Pipilo fuscus aripolius Oberholser. San Pablo Brown Towhee. 



7. Pipilo fuscus albigula Baird. San Lucas Brown Towhee. 



1 According to Oberholser (loc. cit., footnote) this name should take the 

 form alhigulus. However, Baird named the bird Fipilo albigula; even though 

 olhigidus be correct, the fact is that albigula is what the original describer 

 called it, and tliat is also correct!
