It is also rather paler on the under parts than lowi has the feet naked or 
very thinly feathered. 
In lowi the outside of the foot is furnished with a row or mff of feathers and 
in some specimens the inside of the foot is also feathered (see figs. 2 and 8). 
The degi'ee of feathering in amf?/s is a variable feature but it is never as 
in hwL 
Some am^lis were collected at Goraantong in 1929. One had two feathers 
on the outside of the foot ; a second had one feather on the outside of one foot ; a 
third had three feathers on the outside of one foot and in others there were a few 
feathers on both the inside and the outside of the foot. By some authorities the 
foot is said to be naked. 
3. COLLOCALIA FHANCICA MEARNSI Oberh, 
One example of this species was brought to me from Eerhala island in 
Sandakan Bay. The white-nests fi*om Berliala are of exceptionally fine quality : 
it seems feasible that mearnsi is scattered round the coasts of Noi-th Borneo. 
Nothing has been recorded concerning the nidification of this species and it is 
cm'ious that a nest, miknown to science, should have been an article of commerce 
in Borneo for many years. This species can most appropriately be known as 
" Meakns White-Nest Swiptlet. " 
Very little is known about this bird. The single specimen from Berbala 
Island is not unlike the specimens of ameUs from Gomantong hut it is much 
darker ( more blackened on the back ) , and has the rump ( L e. the part of the back 
just in front of the tail ) distinctly paler than the back. The feet were naked but 
it is said that they ai-e sometimes feathered. 
4- COLLOCALIA ESCULENTA CTANOPTILA Oberh. 
This is the species usually^ but erroneously, known as Hnehi, Popularly it 
may be known as " The White-Bellied Swiftlet. " 
In appearance it is quite unmistakable. In size it is much smaller than any 
of the species mentioned above: wing from 100-108 imn. The upjier parts are 
black waslied with metallic green : the throat and breast are grey and the abdomen 
white. 
The white-bellied swiftlet is responsible for the mossy nests which are useless 
from the commercial point of view. Malays call the swifts " Layang-layaug "( a 
name also applied to swallows ) but the Sungei folk of the Kinabatangan River use 
the Sulu *' Kalam Pisau The nests are called "puteh", "itam" and "kmmt" 
with the Sulu "Salang" substituted by the Malay ''Sarang" (nest). 
[In 1914 (Jom-nal of the Straits Branchy Eoyal Asiatic Society) the late 
Dr. J. C. Moulton proposed certain popular names for these swiftlets in his
