640 U.S. NATIONAL MUSEUM BULLETIN 221 



Butler established this form upon a series of five specimens with similar 

 data, four of them in his private collection, one in that of Frank S. Wright. 

 Peters and Griscom {op. cit.) have pointed out that Butler's material in- 

 cluded at least two subspecies, and have restricted the application of the 

 name "to that element in the original series, showing the diagnostic charac- 

 ters of the male shot on Dec. 8, 1879, which is marked 'type' in Butler's 

 handwriting on his original label, and which also carries a U.S. Nat. Mus. 

 type label." 



How many of the original series may be considered cotypes of brunnescens 

 under this restriction is unknown to me, nor have I information on the 

 present whereabouts of Butler's and Wright's skins. 



Genus AMMODRAMUS Swainson 



[(Coturniculus) passerinus] var. perpallidus "Ridgway, Mss." Coues 

 Key to North American birds, p. 137, October 1872. 

 =Ammodramus savannarum perpallidus (Coues). See Van Rossem,

 58605. Adult male. Antelope Island (in Great Salt Lake), Davis County, 

 Utah. June 4, 1869. Collected by Robert Ridgway. Original number 

 1102. United States Geological Exploration of the 40th Parallel. 

 Coues gave no indication as to specimens seen by him, but since he used 

 Ridgway's MS. name, the types should be sought among those examined by 

 Ridgway. In the latter 's report on the ornithology of the Geological Explora- 

 tion of the 40th Parallel, we find but two specimens listed, of which one, a 

 juvenile from Nevada, is hardly worthy of consideration; in the circum- 

 stances. No. 58605, marked by Ridgway himself as "Type," is the only 

 possible type specimen.
