334 Eleventh Supplement to A. O. U. Check-List. Tar 
Sphyrapicus varius daggetti GRINNELL, Condor, III, Jan. 
IQOI, 12. 
Suckow, in 1800, gave a new name (vofkensis) to the northern 
form, which restricts the name “der to the southern form named 
S. v. daggetti by Mr. Grinnell. 
417v. Antrostomus vociferus macromystax vs. 4. macro- 
mystax (cf. RitEy, Osprey, V, 1901, rol). 
No change considered necessary until further evidence of the 
distinctness of the two forms becomes available.

reason for reversing its previous carefully considered ruling on 
these two cases.

(cf. GRINNELL, Condor, III, 1901, 20; RipeGway, Bds. N.

Peuceea vs. Aimophila (of. Ripcway, Bds. N. and Mid. 
Am. &.1g0!, 230.) 
Although there is admittedly no distinct line of demarkation 
between the two groups, as they are commonly recognized, there
