On a further study of Cassin (Proc. Acad. Sciences, Phil. 
1856, p. 194) I feel convinced that his Lusciniopsis hender- 
soni refers to this species, and not, as before supposed, to my 
L. macropus. Lord Walden has received this little wanderer 
from the Andaman Islands. 
25. Creeper-coloured Grasshopper-Lark. Locustella 
certhiola (Pall.). 
The first I got of these was on the 20th May, when some 
native birdcatchers brought me a male. It was sexually well 
advanced, and, strange to say, had its tibial tendons fleshy 
and not osseous, as in all our other Chinese species of Grass¬ 
hopper Lark. So constant did I find this character that I 
began to think it generic. In plumage, it is true, this species 
has a tendency towards Cisticola; but in habits it is neverthe¬ 
less a true Locustella. 
$ . Very flat on the forehead, straight in line with the bill. 
Legs and feet flesh-brown. Bill light brown, black on cul- 
men and tip. Length 5’5 inches. Wing 2*65, its tip falling 
1*6 short of tail-tip, ’55 longer than tertiaries; first quill -3 
shorter than the second, which is the longest, and exceeds the 
third by *1. Under tail-coverts *45 short of tail-tip ; upper 
tail-coverts 1*1. Tail 2*2 long, the outer feathers being *8 
shorter than centrals, of twelve much graduated feathers, five 
on each side being mucronate at their tips, the two centrals 
pointed. Tarse in front '77; middle toe and claw *87. Claws 
long. Bill from forehead ’52, from gape *72. 
On the 31st May Mr. Campbell sent me three from Light¬ 
house Island, and on the 25th June I came upon one in my 
garden flitting from plant to plant. 
26. Wanderer Willow-Wren. Phyllopneuste borealis , 
Bias. 
On the 31st May Mr. Campbell sent me a host of these, 
no less than twenty-three specimens. When I next saw him 
he told me that for a day or two the trees and bushes in his 
island literally swarmed with this bird; and I frequently
