Genus PIPRISOMA, Blyth, 1844. 



The genus Piprisoma contains two species which Sharpe places 

 with Prionocliilus, but which I prefer to keep separate on the 

 ground of their having but nine primaries. 



In Piprisoma the bill is of much the same shape as in Acmono- 

 rhynchus but proportionally shorter. Viewed from above the bill 

 is nearly an equilateral triangle with the two sides sinuated. In 

 this genus the plumage is dull and the sexes are alike. Both species 

 are resident over the whole area they inhabit. 



Key to the Species. 



a. Upper plumage and sides of the head ashy 



green ; lower mandihle coarse P. squalidum, p. 382. 



b. Upper plumage and sides of the head green ; 



mandible slender , P. modestum, p. 383.
