Arakan birds are said to have the ear-coverts wholly 
black, a white spot on the uppermost tertiaries and the. 
lateral tail-feathers still more deeply tipped with white than 
in G. p. pectoralis ; they have been named melanotis by 
Blyth (Journ. Asiat. Soc. Bengal, xii. 1843, p. 949). 
Gecinus canus microrhynchus, subsp. nov. 
In working out the very large collections made by our- 
selves in Peninsular and 8.W. Siam, we have had occasion 
to critically examine the available specimens of the species 
broadly knownas G. occipitalis. One of us has also examined 
the series belonging to the Zoological Survey of India. We 
are in accordance with Stuart Baker in considering that the 
true Gecinus occipitalis (Vigors, P. Z.8. 1830, p. 8) is fairly 
distinct, and can be separated from allied forms by darker 
and duller coloration and size. It appears to be confined to 
the Himalayas west of Nepal. 
Adult g specimens from Muree have a wing of 153; 
from Mussoorie, 158; from “ N.W. Himalayas,” 156 9¢ ; 
and from Simla, 160. Nepal birds are about 153 and are, 
as Baker states, intermediate; while specimens trom the 
stated habitat of his P. c. gyldenstolper range from 139- 
147 mm. — 
We have before us nine birds from Koh Lak and the 
vicinity, S.W. Siam, three from Lat Bua Rao, Hastern Siam, 
three from Cochin-China, and five from 8. Annam. We 
find that the Indo-Chinese and Hast Siam birds agree well 
with the description and figure of Gyldenstolpe in which, 
it may be remarked, the bronzy or olive-gold wings are 
strongly indicated, and they may therefore be placed under 
his name Grecinus c. hesset.
