bangs and penard: surinam birds. 41 



Rallidae. 

 46. Aramides cajanea cajanea (P. L. S. Miiller). 



Six specimens, both sexes, adult and immature, all from Vicinity of 

 Paramaribo, January, February, March, and April. 



A fully adult bird, 268,^ has a uniform, dark, slate-gray crown. In 

 a bird not quite fully adult, 270,^ the back of the head has a tinge of 

 olive-brown, while a still younger bird, 552,^ has the entire head brown- 

 ish with traces of slate-gray. 



Some time ago, (Bangs, Amer. nat., 1907, 41, p. 182) attention was 

 called to a slightly paler and smaller form inhabiting Pearl Islands in 

 the Bay of Panama. On again examining these birds in connection 

 with the new material, we are of the opinion that this form is suffi- 

 ciently distinct to warrant separation and propose the name
