Distribution. Occurs over the greater part of the peninsula of 

 India, from the Himalayas to Ceylon. Its western limits are 

 dillic-ult to define for want of information. It is abundant in 

 South Guzerat, and 1 have seen specimens procured at Dehra aud 

 at Dharmsala, but noue from intermediate localities. It probably 

 follows the margin of the arid region of llajputana, keeping well 

 outside it. To the east it ranges along the foot of the Himalayas 

 to Dibrugarh, and it lias been procured in the Cairo hills. Blyth 

 records it from Arrakan and Tenasserim, and in the latter divison 

 Biugham, as quoted by Hume, once obtained a specimen. 



Habits, $'c. Breeds in March, April, and May, constructing a 

 small nest about 3 inches long, which is suspended from the 

 extremity of a twig on a tree. The nest is made of fine vegetable 

 fibres and down and generally well concealed under some drooping 

 li-avrs. The eggs, usually two in number, are glossless white and 

 measure -58 by "41. 



Genus ACMONORHYNCHUS, n. gen. 



I propose this genus for the reception of a remarkable Flo \\cr- 

 pecker which is found only in Ceylon and which has hitherto been 

 placed either in Prionochilus or in Pachyglossa. It differs from 

 both these genera in possessing only nine primaries. From 

 Dicceum it may be recognized by its very large, coarse bill, and 

 from Piprisoma, by its rounded tail and the numerous hairs which 

 cover the nostrils. 



In AcmoiHjrhi/nckus the sexes differ and the young bird resembles 

 the female. Its habits are those of the family, but nothing is 

 known about its nidification.
