a pair. On August 10, a female (collected) 
was starting a nest in the outer tips of a 
branch some 10 feet from the ground. 
Another female (collected, but unfit for a 
specimen) was observed carrying food on 
August 10. 
Zosterops conspicillata hypolais, Bridled 
White-eye.* — The Yap subspecies, hypolais, 
is strikingly different from all the other races 
of the species. It is by far the most grayish 
race of the species. The eye-ring is inconspic- 
uous and the dark area under the eye is gray- 
ish rather than blackish. The white loral 
region is much reduced. The upperparts are 
gray, with a greenish tinge, most conspicuous 
on rump and crown. The underparts are 
somewhat like those of rotensis but slightly 
more yellowish, less huffy, particularly on the 
flanks. The size seems the same as in most 
other races of this species in which the wing 
varies between 55 and 58 millimeters in 
length in adult males. (Mayr, in litt.) 
This species was usually confined to the 
undergrowth at the edge of the jungle. One 
could find it in numbers from 2 to 15 in 
almost every such area 100 yards long. 
Rukia [Kubaryum] oleaginea, Large Yap 
White-eye.* — This species differs from the 
related Zosterops conspicillata by being 
larger, darker, and more brownish olive. "In 
general coloration it is remarkably similar to 
sanfordi from Ponape. It is somewhat darker, 
particularly on the crown, forehead, and 
lores. There is an extensive blackish zone in 
the malar region and under the eyes, which 
is barely indicated in sanfordi. The under- 
parts also are darker and more grayish, while 
in sanfordi they are more brightly greenish 
buff. Rump and tail, as well as the edges of 
the primaries and secondaries, are duller. The 
legs are duller, more grayish horn color rather 
than yellow as in sanfordi The two principal 
differences between the two species are, how- 
ever, in the shape of the bill, which is nearly 
twice as long as in sanfordi , and in the eye- 
ring which is obsolete in sanfordi The ex- 
posed culmen measures about 14 millimeters 
in oleaginea and over 20 in sanfordi” (Mayr, 
in litt.) 
In the month spent on Yap, only two indi- 
viduals were observed; one on August 6, 1 
mile northwest of Yaptown, Yap Island, and 
one on August 7, less than l A mile from the 
same area. One was in a bush overhanging 
a swamp in dense jungle, and the other was 
in low, thick underbrush 200 yards from a 
swamp. 
Lonchura punctulata, Weaver-Finch.* — 
The three skins agree best with a series of 
the race cabanisi from the Philippines. They 
are also rather similar to the race topela from 
the Asiatic mainland but are distinguished 
from this subspecies by the fine barring on 
their flanks and by a less extensive brown 
area on the throat. (Mayr, in litt.) 
This weaver-finch was found in all open 
and grassland areas on the islands. Flocks of 
40 were observed in the shorter, dry grass 
of the savanna regions, and they were espe- 
cially numerous in flocks of 5 to 20 birds 
along grassy roads -and wide trails where they 
were feeding on seeds. Some immatures were 
begging for and receiving food on August 16. 
This species probably was introduced on 
Yap.
