CORBICULA AndERSONIANA, H. sp. 



Rather small, thin, subequilateral, transversely ovate, tumid ; medium- 

 sized specimens closely resemble in shape G. incdquilateralis, Prime, both 

 sides are obtusely rounded, epidermis bright green, interior violet, paler 

 near the margin. This species is quite distinct from the other Burmese and 

 Indian ones, it is, however, exceedingly close to C. tianida, Desh., P. Z. S., 

 1854, from Borneo, as figured by Issel. 



Type from Momein in Yunnan : long. 20|, hit. 12 mil.

1. Pellorneum pectoralis, n. sp. 



Dese. — Head to nape dull dark chestnut ; back, wings, and tail umber- 

 brown, the last indistinctly barred and with narrow pale tips, the outer 

 primaries edged paler. Lores and frontal feathers pale, tipped with pale 

 black, extending as an obscure supercilium to the nape, where the feathers 

 become broadly dingy white on their upper web, dark brown on the lower, 

 those on the back of the neck are broadly black- centred. The ear- 

 coverts are umber-brown, darker behind, forming a crescentic margin again 

 bordered lighter. The chin is pure white for three-quarters of an inch ; a 

 dark gorget of broadly black-centred feathers then crosses the upper breast, 

 the centering of the feathers becoming very large, oblong, and conspicuous on 

 the elongate feathers of the sides of the neck, but paler and less defined 

 on the flanks. From the gorget all beneath is pale rufescent ochre. The 

 mnder tail-coverts are dark, bordered with white. 



Legs pale ochre. Irides vermilion. 



Wing. Tail. Tarsus, Bill at front.

Hab. — Saddya, Assam (M. J. Ogle). 



This species is nearest and closely allied to Bellornewni Mandellii, 

 W. Blanford, described from Darjeeling, which is the same as Hodgson's 

 P. Nipalensis, a MS. name never published. It is a larger bird as regards 

 wing, and the legs are more robust. The principal difference lies in the far 

 larger extent of the dark streaking on the sides of the neck : the dark centred 

 feathers are longer and broader than in P. Mandellii, the black oblong spots
