Hub. Triton Bay, New Guinea (Mtiller) ; Mysol (Hoedt). 



This is the smallest species of this genus, and one of the most at- 

 tractive. It is very rare in collections, but few specimens having 

 been procured since it was first described by Temmiuck (I. c). It 

 is conspicuous among its relatives from having all the wing-coverts 

 tipped with yellow, and from the blue-grey bands on each side of the 

 breast. 



Male. General plumage bronzy green. Large band of bluish grey 

 on each side of the breast. A purple spot on the centre of the ab- 

 domen. Wing-coverts, scapulars, and tertials tipped with yellow, a 

 greenish- blue shade behind the yellow on the last two. Feathers 

 of the legs whitish. First primary narrowed at tip. 



Wing 2 inches 1 1 lines, tail 1 inch 6 lines. 



Female. Green, without abdominal spot. 



32. Ptilopus monachus.

 Dammar (Bernstein) ; Tidore (Raffray) . 



A series of this bird from different localities brought by M. 

 Raffray is now before me. 1 notice that those from Ternate differ 

 from Gilolo specimens, as well as those from Tidore &c, in being of 

 larger size, and also in having the blue spot of greater extent and 

 situated upon the abdomen, and not on the breast, as in those from 

 Gilolo. The type of Pt. monachus was erroneously stated to have 

 come from Celebes. A specimen in the Paris collection was obtained 

 in exchange from M. Temminck, and the locality given as Celebes. 

 This agrees precisely with Ternate examples, and has the blue patch 

 upon the abdomen. Temminck's figure in the 'Planches Coloriees' 

 exhibits this large abdominal patch very clearly. The Gilolo birds 

 may require separation.
