P. auriventris (Phil. & Landb.) as the type. It differs from 

 Sicalis flaveola (Linn.) chiefly in its wing-formula, in which 

 the outer primary-quills are much longer than the innermost 

 secondaries, while in S. flaveola they are about equal^ and in 

 having a longer and more pointed bill. 



Notiocorys abariensis, sp. nov. 



Adult male. Allied to N. lutescens (Lesson), but differs in 

 being generally paler on the upper surface and inclining to 

 rust-brown, instead of blackish, and in being fawn-colour 

 on the under surface, instead of pale lemon-yellow, and the 

 dark streaks on the breast not so pronounced. 



Total length 129 mm., exposed culmen 11, wing 64, 

 tail 51, tarsus 21. 



Habitat. British Guiana. 



The type of this new Pipit, which is in the McConnell 

 collection^ was collected on the Abary River in November 

 1906. 



Dr. C. B. TiCEHURST exhibited some specimens of Indian 

 birds and made the following remarks : — 



1. Young in down of the Common Indian Sandgrouse 

 [Pterocles senegallen$is^exustus auct.). 



So far as I am aware, the chicks of this Sandgrouse have 

 not been described, nor do I know of any specimens other 

 than these in existence. The down is of two kinds : in the 

 upper parts it is compound or tufted, on the underparts 

 (except the throat and chin) along the edge of the wing and 

 on the tibise it is longer, simpler, and more hair-like. Above, 

 the coloration is pale ginger, broken up by white patterns 

 and lines which are invariably '^ picked out " by black down. 

 Underparts isabelline white, darkest on the throat. The exact 

 pattern does not lend itself well to written description, but 

 I am in hopes that perhaps a coloured plate of the chick may 

 appear in my account of the birds of Sind later on. 1 would, 

 however, call attention to the white " figure of eight " on the 

 crown and another on the back, both outlined by black down 

 and enclosing in the circles ginger-coloured down. In the
