 perceive the great difference alluded to, I annex an accurate admea-

Head, all the upper surface and sides of the chest blue-grey ; 

 lesser wing-coverts and the edge of the shoulder brown ; the remainder

 on the inner edge ; scapularies deepening into slate-grey near the 

 end, and tipped with pale grey ; tail very light grey, the centre fea- 

 thers tipped with blackish-brown ; chin, throat, centre of the breast, 

 abdomen, and under surface of the wing creamy white ; a faint wash 

 of blue on the lower part of the flanks and the under tail-coverts ; 

 bill blue, deepening into black on the sides of the nostrils, at the tip 

 and along the side of the lower mandible ; irides brown, legs beau-

Remark. — As the name I have assigned to it implies, this species 

 differs from every other member of the genus in the extraordinary 

 size of its bill. In form and colouring it is precisely similar to the

 specific characters.

Mem. Z.S. 



Having lately procured a specimen of this rare and interesting fish 

 (which I have had the pleasure of presenting to the British Museum), 

 I beg leave to lay before the Society the result of my observations 

 upon it when in a fresh state. The remarks I shall make will be 

 for the most part supplementary to Mr. E. T. Bennett's long de- 

 scription of another specimen from this locality, printed in the first 

 volume of the 'Transactions of the Zoological Society*;' but I hope 

 they will be found to have some bearing upon the question of the
