Since the type of tlii.s vaii.>ty was ol.taim-d, two other specimens (Nos 

 53,418 9, and r,:i,4l!) ^, ,S(3,,teuil.er, 1,S(;7 ; II h'id-way) have hcen secured 

 by the I nited States Geological .Survey of tiic 4utli I'arallel, in conuuand of 

 Mr. Clarence Kin-, in the West Humboldt Mountains, Nevada. These 

 specimens are even more ditlcrcnt from true m/ifarias tlian is the type of this 

 race, showing that it is really distinct, as a variety. In the sanu> tliickets 

 at the same season, perfectly typical specimens of V. Holitarim were obtained : 

 the latter having, no doubt, come from their more northern sunmier home 

 on their pas.sage southward into ]Mexico. 



In ilie Humboldt Mountain sjiecimens the crown shows no trace of ash, 

 and is even darker and more brownish than the back. In fact, the relation 

 of the V. casKlni to F. xolitaru, is an almost exact parallel to that of V. 

 josqyha' to V. i/ihiis, as lar as c(.loration is concerned, in each case tlie ex- 

 treme being widely dilferent, but connected by specimens showing inter- 

 mediate characters. 

 Nothing is known of the habits of this race.

As the specimen in linest plumage 

 (described above) is moulting the 

 quills, th(> measurements are taken 

 from another (,^7.01()). In this the 

 first qnill is not quite one third the 

 second, wliieh equals the sixth, the 

 third and fourth longest.
