THE MALAYAN BROWN WHITE-THROATED BULBUL.
Criniger tephrogenys tephrogenys, Fauna B. I., Birds, 2nd ed. vol. i, p. 362.

As this bird was described by Moore from a Tenasserim bird, its trivial name would have been better if given as “The Tenas¬serim” rather than “The Malayan.” However, as it is only found in the South of Siam and Tenasserim and, apparently, all through the Malay States, I forbear to change the name more than necessary.
There is nothing on record about the nidification of this Bulbul, but it will probably be found to be much like that of the com¬paratively well-known Indian White-throated Bulbul, very fully described further on. It is a bird of the hottest and most humid evergreen forest, haunting the valleys, low broken hill country and the adjacent plains, especially those forests where there is much green undergrowth, How far up the hills it ascends I do not know but, probably, not more than about 2,000 feet ; further information is, however, wanted on this point.
The only known nests, with eggs, are four taken by Kellow near Simpang (1906), Taiping and Perak (1910). “Near” apparently means within 20 miles.
The nests are described as “very massive, strongly but loosely built cups of dead leaves, twigs, roots and weed-stems, bound together with longer roots and stems and lined with coarse roots and tendrils.” All were placed low down in thick bushes or tangles of creepers in evergreen forest on the banks of streams. One of the parent birds and a nest were sent to me with the series of eggs.
The nest sent to me has a thick lining of bamboo-leaves between the walls of the nest and the true lining. There is also a little moss, probably green when used, fastened into the walls of the nest.
The nests were taken between the 11th of March and the 3rd of May, but some found early in March were too hard set to blow.
The eggs, like all other eggs of this genus, are extremely beautiful. The ground-colour of the small series referred to above varies but slightly from a rosy pink to a deeper rosy with a tinge of carmine. The markings of the darkest clutch consist of broad scrawls, small and big irregular blotches, some of which look as if they had run, and spots of deep purple-red or reddish-black. Similar marks of brick-red underlie these, whilst deeper still there are faint spots and blotches of lavender and violet showing through the rosy ground-colour. At the larger end all the markings are numerous and occasionally form indefinite caps or rings ; elsewhere they are less numerous, though nowhere scanty. The palest clutch has far fewer markings, especially of the darker kinds but, on the other hand, has far more pale reddish smears and blotches, which only show up well Under a good glass. The two other clutches are intermediate, though one has the markings very blurred and dis¬tributed equally over the whole egg.
The texture is very fine and intensely glossy, far more so than in the eggs of any other genus of Bulbul I know of ; the shell, also, is stouter in comparison with its size.
Eleven eggs average 25.2 x 18.5 mm. : maxima 27.0 x 19.6 mm. ; minima 23.9 x 18.6 and 24.1 x 17.3 mm.
