NATURAL HISTORY OF BIRDS. 



which consists of ten rectrices only. In some forms the exterior pair of tail-feathers 

 is curiously recurved and twisted. In Dicranostreptus megarhynchus^ from New Ire- 

 land, the outer tail-feathers are extraordinarily produced, being nearly double the 

 length of the bird's body, and in the genera Bhr'uu/a and Dissemurus, from India 

 and Malayana, they are ending in a, racket or spatule, many of the species having 

 curious frontal crests. We quote from Jerdon : " They are birds capable of strong, 

 rapid, and vigorous, but not of sustained, flight ; and they feed almost exclusively on 

 insects, which they capture on the wing, or on the ground, or occasionally on leaves 

 or flowers. They are a most characteristic featui-e of Indian ornithology; for, go

 a hawk with claws and beak for some seconds, as Mr. Philipps asserts that he has
