Habitat. Fernando Po, West Africa. 
The aspect of this bird is that of a Phylloscopus, but the 
beak is longer, more depressed at the base, the culmen cari- 
nated, the wings short and rounded, the first quill subspurious, 
the fourth longest; tail much graduated, rectrices narrow; tarsi 
moderately long, acrotarsia scutate, toes slender, the outer 
longer than the inner. These characters induce me, (says 
Mr. Strickland,) to class the bird provisionally in the genus 
Prinia, 
From Mr, Fraser’s collection.
