276 MILLER, Abnormal Color Markings. ie 
every other way, has all the white feathers of the rump marked 
subterminally with round or subcordate spots of black. The 
larger feathers of the rump are in addition crossed or nearly 
crossed by from one to three black bars, each of which tends to 
narrow near the shaft so that occasionally the constriction divides 
the bar into two distinct spots. 
In the Cuban Colaptes chrysocaulosus the color is similar to that 
of C. auratus except that it is everywhere strongly suffused with 
tawny, the black markings are more extended, and the feathers 
of the white rump patch are closely and irregularly barred with 
black. Each rump feather in this species has a subterminal 
broadly cordate black spot extending nearly across both webs. 
Usually a broad black bar and sometimes a second (the latter 
always indistinct) crosses the feather below the terminal spot. 
The proximal bars tend to narrow near the shafts of the feathers, 
but they seldom if ever break up into pairs of spots as in the 
abnormal C. auratus. 
The peculiarities of its rump markings make No.5619 an almost 
perfect intermediate between Colapies auratus and C. chrysocaulosus. 
Did the breeding ranges of these two species overlap this speci- 
men would probably be considered by many a hybrid, since 
so-called hybrids often blend the characters of their supposed 
parents no more perfectly than this Flicker does the peculiarities 
of the Continental bird and its Cuban representative. 
Nucifraga columbiana (W7/s.). 
One Clarke’s Nutcracker in the series of thirty-three skins in 
the U.S. National Museum (No. 99858, Mt. Lassen, Calif., June 
23, 1884) has most of the greater and lesser wing-coverts spotted 
with white. The spots, though small, form wing bars nearly as dis- 
tinct as those normally present in the European Wucifraga caryo- 
catactes. The wing-coverts in adult V. columbiana are normally 
plain, but the extreme tips in immature birds are usually very pale 
gray, thus forming a distinct contrast with the rest of the feather. 
Pipilo erythrophthalmus (Vzev//.). 
A Towhee from North Truro, Mass. (¢ ad.. No. 4208, Miller 
collection, August 12, 1889) is normal in all respects except that
