composed and garnet brown, forming a conspicuous patch as 

 in Leucotreron marchei, but the patch smaller and its color 

 darker than in the latter species ; on each feather at the base of 

 the decomposed area a narrow blue streak, about Roslyn blue; 

 feathers of alula chsetura black, edged with green; wing-lining, 

 axillars, and greater part of inner webs of primaries and second- 

 aries pecan brown; rectricies above forest green, shafts black, 

 below deep gull gray, the tips paler, shafts white. Iris dark 

 carmine ; bill ox-blood red, tip dirty deep chrome ; legs, feet, and 

 bare skin around eye ox-blood red; nails buffy brown, tips 

 black. Length, about 340 millimeters; wing, 165; tail, 125; cul-

Fig. 1. Leucotreron merrilU McGregor, sp. nov., generic details. One-half natural size. 



Distribution. — Pohllo Island and Laguna and Albay Provinces, 

 Luzon. 



Remarks. — This very conspicuous species was discovered in 

 Polillo Island in October, 1909, but the single specimen obtained 

 at that time was recorded as Leucotreron marchei, as I 

 suspected that it might be an immature bird. However, six 

 specimens collected near Paete, Laguna Province, Luzon, are 

 adult breeding birds and there can be no doubt that they rep- 

 resent a perfectly distinct species. I have recently examined 

 a living bird of this species which was captured in Albay 

 Province, Luzon. The sexes are alike in plumage. 



Specimens of Leucotreron TYierrilli collected in June were 

 feeding on the fruits of Symplocos ahernii Brand, a small timber 

 tree of minor importance. It is probable that this species and 

 the other forest-inhabiting pigeons are important agents in the 

 distribution of the seeds of trees.
