then advance "8 on to the centre of the pouch, and terminate in 

 an imperfect angle. 



(3.) $ . Round the eye bare. The plumes advance on the 

 forehead to about 'S in. beyond exterior plane of eye towards the 

 commissure only slightly in advance of the eye ; they then recede 

 inwards and downwards "5, and, forming inwardly an angle of 

 about 80°, advance on to the gular pouch about '8, terminating 

 in an angle of 45°. 



(4.) (5' . Round the eye bare. The plumes advance on the 

 forehead to just over the middle of the eye, form an obtuse 

 angle towards the commissure in about the same plane, and 

 then recede well clear of the lower jaw, advancing again on to 

 the gular pouch "6, and terminating in its centre in an unde- 

 termined angle. 



Of P. major we read (/. c), "tour de I'oeil et region des 

 freins nus. La partie emplumee du front formant par devant 

 une ligne convexe, et depassant Fceil de six ligues. Les plumes 

 des joues s^avancent vers la base de la mandibule inferieure 

 jusqu^au deljl de Fangle de la bouche, et celles du has du cou 

 se prolongent jusque sous I'aplomb de Fceil, en formant sur la 

 peau nue de la gorge un angle aigu." 



In the frontal plumes this description of P. major closely 

 agrees with our (1), but in that of the gular plumes with our (2); 

 I suppose, therefore, it is the intermediate plumage. 



In P. minor the feathered forehead, it is said, is " un peu 

 echancre par devant, et ne depassant guere le bord anterieur de 

 I'oeil." So far it would agree with our (2). But "la partie 

 emplumee des joues ne s'avance que jusque sous le bord 

 posterieur de I'oeil." This last shows a greater expansion of 

 bare skin than in our most developed (4). I suppose therefore, 

 for the present at least, we must allow P. minor to enjoy its 

 rank as a species, and take to oui-selves the merit of only having 

 discovered the mature development of P. major. 



The rectrices in our bird number 12, and are of equal length. 

 The tertiary quills extend to the end of the primaries. 



Now for a few facts brought to light by dissection. 



(1.) $. Ovary minute. Stomach nearly empty, containing 

 exuviae of Crustacea, small fragments of drift-wood, and morsels
