Two skins of this curious bird are in the collection. They may 

 probably be females of a more brilliantly coloured male ; but the 

 form, which appears to belong to the Piprince, is quite new to us. 



136. Cotinga cayana (Linn.). 

 Locality not recorded. 



137. Cotinga porphryol^ema, Sclat. et Dev. Rev. Zool. 1852, 

 p. 226, et Contr. Orn. 1852, p. 136, pi. 96 ; Des Murs, Zool. Voy. 

 Casteln. Ois. p. 65. 



Hab. Sarayacu. 



A pair of this beautiful Cotinga, which was, we believe, first dis- 

 covered by Poeppig in the province of Maynas, although his specimens 

 remained unnamed in the Leipsic collection until after it had been 

 described by Sclater and Deville from the specimens obtained during 

 Castelnau's expedition. Hawxwell also obtained specimens of this 

 Cotinga on the Ucayali, some of which are now in the British Museum. 



138. QUERULA CRTJENTA (Bodd.). 



Several specimens, all from the Upper Ucayali. 



139. Cephalopterus ornatus, Geoffr. 



Order II. PICARI.E. 

 Fam. Momotid^e. 



140. Momotus brasiliensis, Lath. 

 Upper Ucayali. 



More rufous below than Sclater's specimens ; but these birds ap- 

 pear to vary much with every slight change of area. It will pro- 

 bably be necessary to reduce the number of species allied to M. bra- 

 siliensis when we have a better series of examples. 



141. Momotus martii, Spix. 

 Hab. Upper Ucayali. 



Fam. Alcedinid^e. 



142. Ceryle torquata (Linn.). 

 Hab. Lower Ucayali. 



Mr. Bartlett has also sent the eggs of this Kingfisher, which are 

 glossy white, like those of other members of this family.
