Length (fresh), 5% in. ; wing, 22; tail, 24; tarsus, 7. 
Two specimens marked as females do not differ in plumage from 
the males. 
Length (fresh), 54 in.; wing, 24; tail, 23; tarsus, $. 
Another specimen, marked male, and of quite different colors, I 
have no doubt is the young of this species ; though Mr. Ober, in his 
notes, says of it (No. 428): “ The quickest to respond to my call on 
the Soufriére, was this little bird. It seems an associate of the pre- 
ceding species (Z. Bishofi), though I never saw them closely togeth- 
er; yet in general shape and habits, especially in search for insects, 
they resembled one another. As I have got both male and female 
of the other, it precludes the possibility of its being the adult of the 
former. That there may be no doubt, I have preserved one in rum.” 
The color of this specimen (No. 428) is of a dark olive-brown 
above, lighter below, and where the white markings are in the adult, 
it is of a pale dull rufous; on the throat showing some white, and 
around the eye partially white ; the marks on the ends of the tail- 
feathers are precisely as in the black specimens ; the quills are dark 
brown ; the tail-feathers are black. But what I consider conclusive 
evidence of its being the young of Z. Bishop is, that on the crown 
the black feathers are beginning to appear. Had it not been marked 
as a male, I should have taken it for the female of this species. But 
according to Mr. Ober, the sexes are alike.

REMARKS. This is a remarkable species, and at first I was at 
a loss where to place it properly ; I determined it to be a Sylvico- 
line form, yet unlike any of that family in coloration. On comparing 
it with the description and plate of Leucopeza Sempert, Mr. Scla- 
ter’s new form from St. Lucia (P. Z. S., 1876, p. 14), I determined it 
to be a second species of that peculiar genus, and, like that species, 
having long and light-colored tarsi. 
Mr. Ober requested that I would bestow the name of our friend 
Mr. Nathaniel H. Bishop on some West India bird of his procuring, 
if the opportunity offered ; and it gives me much pleasure to connect 
his name with so remarkable a species. 
The habits of this bird would seem to be like those of the wren, 
as Mr. Ober has on the labels, “Wren?” He states that they are 
“very rare and very shy, and found in the crater and dark gorges of 
the Soufriére.” 
Three specimens were obtained in November, 1877, and one in 
February, 1878.
