90 Four New Species of Birds from Costa Mica. 



Remarks. In appearance this species resembles 8. cayenn- 

 ensis, but the tail is longer with narrower feathers ; it wants 

 the transverse black bar midway on the tail feathers as in 8. 

 cayennensis, and has the abdomen and under tail coverts 

 more rufous than in that species. 



This appears to be the first occurrence of a member of 

 this genus north of the Isthmus. 



3. Geotrygon ruflventris. 



Frout and a line under the eye extending as far as the occiput, light 

 salmon color; crown, hind neck, upper part of back, throat and upper 

 part of breast, of a rather dull violet-purple, on the lower part of the 

 breast merging into brownish-ash ; lower part of back, rump, and upper 

 tail coverts of a dull bronzy olive-green; tail feathers brownish-black, 

 the ends lighter or ashy-brown ; abdomen, vent and sides dull brownish- 

 rufous, on the middle of the abdomen is a patch of white feathers just 

 tinged with rufous; under tail coverts dark brown largely ending with 

 rufous; wing coverts, secondaries and tertiaries olive-brown, primaries 

 brownish black, the shafts of a reddish or hazel-brown ; under wing 

 coverts and axillars deep cinnamon-red ; inner webs of primaries at base 

 dull pale cinnamon ; bill black; feet in the dried specimen of yellowish- 

 flesh color. 



The sex is not given. 



Length about 9 in. ; wing 5$; tail 34; bill from front |, from rictus 1 ; 

 tarsus If. 



Habitat. Costa Rica, Talamauca. Type in National 

 Museum. 



Remarks. The number of handsome species of this genus 

 discovered in Central America within the last few years is 

 quite remarkable, this making the sixth ; it is however much 

 more sombre looking than most of its allies, the colors being 

 darker and more subdued. It is so unlike all others of the 

 genus that no comparisons are required. 



4. Porzana cinereiceps. 



(Female. Upper part of head and cheeks bluish-cinereous, darker on the 

 crown, but clearer and lighter on the cheeks ; neck before and behind, 

 upper part of back and breast bright reddish-chestnut, paler on the throat 

 And grayish near the chin ; back olivaceous-brown, on the rump and upper
