of Hongkong, Macao, and Canton . 
see no further difference to justify a separation ; but there seems 
a strong tendency towards Parus cinereus of Java. 
35. Zosterops 
An abundant resident at Hongkong, where it may constantly 
be seen, roaming from tree to tree along the roads in small parties. 
Its well-blended tints of yellow and green, and the snow-white 
ring that encircles its sharp black eyes, may be seen to advan¬ 
tage by the observer that stands under the tree whereon these 
sprightly little fellows are exploring the twigs and leaves for 
small insects. On the 2nd of April I had the good fortune to 
discover its nest at the end of a bough of a large-leaved tree. It 
was attached to several leaf-stalks about 8 feet from the ground, 
and might at first sight have been mistaken for some insect's 
nest. It consisted of a small cup, composed of delicate grasses, 
spider's-web, and moss, and resembled much the nest of a 
Humming-bird. This pretty little structure contained two clear 
white eggs, one of which was slightly punctured. The nest and 
eggs I enclose to Mr. Sclater. 
36. Motacilla boarula, Linn. 
I frequently saw this bird, and from meeting individuals with 
food in the mouth, I feel sure they breed in Hongkong. A male 
and female, procured in summer plumage, I transmit for com¬ 
parison with the European bird*. 
37. Motacilla luzqniensis, Scop. 
This bird was pretty abundant in February; and in March I 
witnessed the assembling of immense flocks on the tops of the 
houses, evidently preparing for migrating. A few weeks later 
they had all gone. 
38. Motacilla ocularis, Swinh. 
A resident species. I enclose a male in complete summer 
plumage for comparison with the Indian species of the Pied 
Wagtail group. It greatly resembles M. lugubris, but the grey 
back in summer is a sure distinction. 
* These examples do not appear to differ from the European M. boarula.
