CALAMOHERPINiE. 157 



1st quill nearly half the length of the 2nd, which is a little shorter 

 than the 3rd and 4th, which are equal and longest, and the 5th is 

 nearly as long ; tail somewhat long, much graduated, the 

 feathers narrow; tarsus moderate, stout; feet strong; claws leng- 

 thened, moderately curved. 



The peculiar form has quite the general aspect of Acrocephalus, 

 but differs in its much wider bill, and the form of the wing. Some 

 class it along with Megalurus and Chcetornis, but its somewhat 

 more lengthened wing, and broad, little compressed, bill, are against 

 this view, whilst its colors are quite those of Acrocephalus 

 brunnescens, to which its general resemblance is so strong that I at 

 first passed it over.

I first procured this species in the Carnatic near Nellore, where, 

 however, it is not very common ; and Mr. Blyth subsequently 

 obtained it tolerably abundant in the vicinity of Calcutta. It 

 has also been procured in the Nepal Terai, and in Tenasserim, 

 and probably frequents suitable localities over most parts of 

 India. I presume that like the last it is migratory. 



Gen. Dumeticola, Blyth. 



Char. — Bill straight, as in Cinclus, but shorter, stout, compressed, 

 strongly notched at the tip ; gape smooth ; tail rounded, moderate ; 

 wings short, the first three somewhat graduate, 4th longest and
