630 The American Naturalist. [July, 
size of the oriole, has some bright color, though the general 
tone is sober, and has that bare or bald circlet around the 
eye which imparts a singular aspect to the face. The bird in 
question is Sphecotheres salvadorii, so named from the eminent 
Italian ornithologist. There is much olivaceous, becoming 
almost yellow around the body, running into a bluish gray 
about the throat and side face, white on the abdomen, yellow 
on the upper portion, white in wide patches on the outer tail 
feathers, the inner ones black, jet black on the crown as far 
as the staring spaces enclosing the eyes. The female is clad 
in dusky brown or slate mainly, mottled by darker spots on 
the upper surface, the under parts with running spots or irreg- 
ular lines of olive or dusky over a pale yellow ground. The 
tail is marked similarly with that of the male, only brown 
takes the place of black, and dull yellow of white on some of 
the feathers. Clear white occurs about the vent and an open 
spot around the eye. Mr. Stone collected this bird as well as 
Oriolus striatus, a true oriole, common, probably, over the island. 
In this case the general coloration is not greatly unlike that of 
the female above described, with, however, a purer brown both 
above and beneath; but the distinctive feature of the striatus, 
as the name implies, rests in the streaks which appear almost 
everywhere in narrow or broader lines over the body and 
even monopolize the crown of the head. In fact, about the 
only parts free from these long black, brown or gray streaks 
are the wings and tail, yet these are lined off or margined 
with slightly different tints. The female does not show mark- 
ings at variance with those of the male. The length is a good 
12 inches. 
Hattam Thickhead (Pachycephalopsis hattamensis), is a 
small bird about 7 inches in length, found in the moun- 
ains of Northwest New Guinea. The sexes do not differ 
in color or size. Back and wings are a deep olive which 
becomes a mere line on the wing-coverts; these are almost 
black. The under-wing coverts and tail are a light brown 
somewhat varying in shade. The head and nape of neck are 
gray, the lores white, as are also the chin and throat. Lower 
down this changes into a greenish yellow, shading off on the 
abdomen. Bill and feet dark.
