white. [In Prinia inornata Sykes. the lores are brown.] Another allied form to Pri- 

 nia inornata is Prinia extensicauda Swinh, from China but that species differs from 

 the first-mentioned in being much greener above and more yellow below. It also 

 differs from Prinia hlanfordi Wald. in having the bill black even in summer as in 

 other particulars. In Prinia hlanfordi Wald. the bill is said to be brown both in 

 summer and winter but in Prinia inornata Sykes. the bill is black during the sum- 

 mer and during the winter brown with the base of the lower mandible of a påle 

 liorny fleshy colour. In my specimens, however, the one shot on the 31st of Janiiary 

 and the other on the 8tli of February, tlie bilis are of the same colour as those 

 of Prinia inornata Sykes. during the winter time. 



I believe my specimens are young birds after their first moult. They are 

 more rufous than old birds especially on the edges of the quills and the tail-feathers, 

 but the subterminal band on the tail-feathers are clearly distinguished in my spe- 

 cimens, wliich is said not to be the case in young birds.

41. Lanius nigriceps longicaudatus GJould. — The Black-headed Shrike is 

 represented in Siam and Cochin China by the above-mentioned subspecies which is 

 distinguished from the typical Lanius nigriceps Frankl. by being as a rule of more 

 bright colours and also being of greater dimensions. This species was never observ- 

 ed in Northern or in Fastern Siam, though it was not uncommon in the bamboo- 

 jungles in the Central parts of the country. The specimens in my coUection are 

 from the neighbourhood of Tha Law and were shot one day at the beginning 

 of April, and at this time the species seems to be moulting. Especially the tail- 

 feathers are very much worn why the tail measurements are very uncertain.

42. Lanius cristatus L. — The Brown Shrike is only a winter visitor in this
