ZOSTEROPS NIGRORUM ‘Tweed. 
The discovery of the Negros silver eye on the little Island of 
Cresta de Gallo was the most surprising find of our trip. The 
species is found in Masbate to the eastward and in Negros to the 
southward of Cresta de Gallo, but has not been taken in Sibuyan 
and almost certainly does not exist there, although the two last- 
named islands have but 8 miles of water between them. Our speci- 
mens differ from the Masbate and Ticao bird in having slightly 
longer bills; no other difference is observable.

In their “Preliminary Notes” Bourns and Worcester described 
the thickhead of Cebu, Tablas, and Sibuyan and named it H. 
major. Later, in their “Distribution List,” the same authors have 
birds from the above islands lsted under H. winchelli, which, 
judging from Masbate and Sibuyan birds, seems to be correct. We 
secured seven specimens in Sibuyan, where the species is somewhat 
scarce. 
ARTAMUS LEUCOGASTER (Wagler). 
Abundant in Romblon and Sibuyan. 
LOCUSTELLA OCHOTENSIS (Middend.). 
One specimen of the Middendorf grasshopper warbler, secured 
in Romblon, is a new record for the province. 
MEGALURUS RUFICEPS Tweed. 
Specimens from Romblon and Sibuyan; abundant in the latter 
island. 
CISTICOLA EXILIS (Vig. and Horsf.). 
One specimen taken in Romblon, where is appears to be soméwhat 
rare and confined to the highest hills. A nest of this species 
containing three incubated eggs was found in Sibuyan July 5; 
as shown in Plate IV it is supported by a number of grass stems 
which stand 12 or 14 inches above the domed roof and at the same 
time serve to conceal the nest. The nest is composed of dry grass 
blades not very closely interwoven and is lined with spider silk, 
except at the bottom, which is provided with a thick mat of fine
