eleven, and the inner feathers comparatively short. The nostrils 

 are pervious, the tongue is lanceolate, the furcula is U-shaped, 

 the after-shaft is diminutive, and the powder-down patches are 

 abundant, though writers differ as to their extent. E. helices — 

 as Prof Newton says in his excellent account ^ — is not to be 

 described in a limited space otherwise than generally ; it has a 

 black head, with a white stripe above and under each eye, and a 

 white throat : the remaining plumage " being variegated with black,

 lines and spots of darker brown and white. The sexes are similar.

 nearly conceals the body. The note is a soft or plaintive long-
