(li>.i;»): tlepth of hill at base, 7.02-S.ia (7.87); tarsus, 12.95-13.21 

 (1P».21); middle toe, 9.91-11.43 (10.()7).' 



Mountains of southwestern Mexico, in States of Durango (El Salto, 

 Cliaeala, Ciudad Durango), Zacatecas (San Juan Capistrano) and 

 Jaliseo (San Sebastian) and Territory of Tepic (Santa Teresa). 



The adult male of this well-marked form resembles in coloration the 

 adult female of ,5'. n. notatus, but the olive-j'^ellowish color of the rump is 

 iiuich more strongly contrasted with the olive-green of the back, and 

 the black of the throat extends much further backward. In fact, the 

 ])attern of coloration is precisely the same as in the adult male of 

 xS". ;/. ;?r>to^?(5,S', and I therefore believe that the type of S.fovrerl^ supposed 

 ])y its describers to be an adult male, is in reality an adult female. At 

 any rate, it agrees minutely in coloration with adult females in the 

 collection of the Biological Survey, obtained in the States of Zacatecas 

 and Jalisco, by Messrs. Nelson and Goldman.
