Sp. char. Bill stout, straight, variable in length, usually about equal to 
the head, the tip considerably expanded and punctulate. Feathers extending 
on the b^se of the bill to a nearly equal distance on both mandibles, their 
outline straight and vertical ; those between the rami reaching but little fur- 
ther. First primary usually longer than the second, the rest equally gradu- 
ated. Upper tail coverts very long ; tail moderate, doubly emarginate, cen- 
tral feathers pointed and projecting. Adult. — Upper parts variegated with 
ashy, pure black, bright chestnut and white, each feather having a terminal 
black field, and being margined with reddish and tipped with white or ashy. 
Tertials dusky brown, edged with ashy or light chestnut ; wing coverts and 
secondaries dusky ash edged with ashy white. Primaries deep dusky ; shaft 
of the first white, the central portions of the others the same, their bases brown 
and tips black. Rump and upper tail coverts brownish black, the outer pair 
of the latter white barred with dusky. Central tail feathers dusky brown, 
the others light greyish ash scarcely edged with white. Beneath white ; the 
throat and breast slightly rufescent, and with oval or cordate spots of brown- 
ish black, most numerous across the breast, and extending sparsely along the 
sides as shaft lines. Middle of belly and under tail coverts white, mostly 
immaculate. Bill and feet greenish black. 
Length 6 '5, wing 3*75, tail 2T ; bill (average) 1 inch ; tarsus *85, toe *8, 
tibia, bare, *50. 
Habitat. — Entire temperate North America. Bahaia Islands. 
The present bird, the single admitted* American representative of a genus 
* I am by no means satisfied that but a single species of Ereunetes exists in North 
America. The differences in size, in length and proportions of the tarsus even, and es- 
pecially in the bill, cause it to seem almost impossible that all the specimens before me 
are specifically the same. Thus, the difference in the length of the tarsus, between the
