Hah. Costa Rica, to and including Ecuador, 



Male. Top of head shining metallic-green. Under surface hronzy-green ; chin 

 black ; throat and breast violet-blue. Sides of neck green like the crown. Under 

 surface gray washed with green on the flanks. Upper tail coverts and median 

 rectrices reddish-bronze, lateral rectrices black. Wings purplish-brown. Maxilla 

 black, mandible flesh-color, tip black. Total length, 3j in. Wing, 2| in. Tail, 1| 

 in. Culmen, f in. 



Female. Above bronzy-green, beneath gray. Median rectrices bronzy-green, 

 lateral ones bronze at base, then black, and tipped with grayish-white. Dimen- 

 sions like the male. 



Some specimens have the metallic-green of the crown continued on to tlie occi- 

 put, even on to the nape. I do not think, however, that this in any way indicates 

 the existence of two species. 



Next to Damophila comes the genus Iache, consisting of three species, two of 

 which are extremely rare and but little known. They are small birds with con- 

 siderable brilliancy in their plumage, and it is believed that the coloration of the 

 sexes is totally unlike in all the species. The generic term Circe, in which these 

 birds have generally been placed, cannot be continued, as it is preoccupied for 

 a group of Acaleps; I therefore propose Iache, which I believe has not been pre- 

 viously employed. * 



Genus CXV.— IACHE.' 



Circe, Godlu, Intr. Troch., octavo cd., p. 168 (noc Mekt., 1835, Acal.). 



Ch. "Bill rather longer than the head, slightly 

 curved, and tapering towards the tip ; wings rather 

 long; primaries rigid (!); tail rather short and slightly 

 forked, the feathers broad ; tarsi clothed ; feet small ; 

 hind toe short."— (Goidd, 1. c.) Sexes unlike. 

 Ranye. Mexico.
