Just as the two before-described birds seem to represent our 

 Sylvia trochilus and Regulus, so it seems that this bird supplies 

 the rjiace of our Troglodytes in India, to which it bears, the co- 

 lour excepted, a close resemblance. Its much larger feet and 

 smaller wings give it a strange appearance. Like Troglodytes it 

 hops restlessly and boldly about, often, but not at all times, with 

 its tail spread out, and is seldom quiet. It also seems often to 

 make signs as if it would attack the person who approaches it ; 

 but it hops only in trees, generally in the lower ones, and not 

 among stones, &c, as Troglodytes. Its note is a loud whistling 

 tshuti ! tshuti ! I did not hear any clear sounds. According to 

 a description in Lath. ' Gen. Hist/ it builds its nest between two 

 leaves of the mango-tree. I found in its stomach only the re- 

 mains of finely-chewed insects. In the entrails of both the males 

 were found a great many intestinal worms as fine as threads in 

 the neighbourhood of the kidneys, and it seemed as if the liver 

 of one had been gnawed by them, yet the bird appeared to be 

 quite lively and gay. Three of the males I examined were with- 

 out those worms. The liver in all of them was of a whitish colour, 

 which was quite common among the Bengal birds. This kind is 

 common in the neighbourhood of Calcutta. It is met with all 

 over India and China. In Java (and Sumatra ?) there is a kind 

 which is very much like this, and ought perhaps only to be consi- 

 dered as a variety*. Dr. Mellerborg, who visited Java in 1827, 

 likewise through Baron Gyllenkrok's patronage, has brought se- 

 veral specimens of them, but only on his second visit.
