104( TRERON TEYSMANNII. 



de grisatre sur les autres parties et se répandant unifor- 

 mément sur tout Ie dessous de l'oiseau. De larges lisérés 

 jaunes aux couvertures alaires grandes et moyennes, plus 

 étroites aux rémiges secondaires. Blanc grisatre du dessous 

 des rectrices clair et occupant plus du dernier tiers de leur 

 longueur. Souscaudales vertes , mais tres largement bordées 

 de blanc roussatre." We have seen by this general diagnosis 

 of the two species , that the male and female are of the 

 same coloring, or in other words, that the male has not, 

 as in Treron aromatica and griseicauda , the shoulders 

 dark grey , nor the shoulder-feathers and the mantle tinged 

 with brownish red inclining to purple. Our new species 

 showing this same color, only on the hindest part of 

 the mantle and the hinder shoulder-feathers, this circum- 

 stance leads to an addition to the diagnosis of the subdivi- 

 sion , giving at the same time a very conspicuous character- 

 istic to our new species. 



In size, Treron Teysmannii is superior to Treron floris 

 and even a little to Treron psittacea, the wing measuring 

 six inches to six inches and four lines; the tail however, 

 is of the same length as in Tr. psittacea, whereas it is a 

 third of an inch shorter in Treron floris. The bill from 

 front to point has in length seven lines and is of a greenish 

 horncolour. The tarse and toes appear to have been of 

 a greenish gray. 



Front , throat , rump and upper tail-coverts greenish yel- 

 low. Under part of body yellowish green. The middle 

 pair of tail-feathers yellowish olive color. The other tail- 

 feathers grayish at the base, passing into a large band of 

 dark bluish gray, while more than the last third of these 

 feathers is of a grayish white color which spreads 

 also over the upperside of the other tail-feathers, but in 

 decreasing extension towards the outer feathers. Under 

 tail-coverts green , very broadely margined with fulvous 

 yellowish white. Crown and sides of the head, neck, 

 small wing-coverts , shoulder-feathers and mantle green with 

 a grayish hue; with the exception of the hindest part of
