type in having the -white of the lower parts tinged, or rather stained, with a 

 beautiful, delicate rufous or almost a salmon-orange. The terminal band of 

 the tail also inclines decidedly to this color, while the white of the under 

 surface of the wing (particularly towards ends of secondaries and primaries) 

 is tinged with a more pinkish shade of the same. 



Another of Mr. Lawrence's specimens differs in the clearer white beneath 

 (that is, with less reddish tinge the pureness and continuity does not vary) 

 which extends entirely around the neck, giving a sharper definition to the 

 black pictures. The " moustache," however, is almost entirely absent ; the 

 black transverse spots on larger posterior scapulars are rather more conspic- 

 uous, and the terminal band of the tail is more purely white. 



Adult Female. (31984, Cuba, J. Ackhurst.) Generally similar to sparve- 

 rius, but rufous brighter, the bars narrower and less numerous, the nape or 

 upper part of back, and rump being almost immaculate. Tail with ten black 

 bars, these scarcely touching the shaft ; the last is about -36 wide, the others 

 about -16 ; tip of tail scarcely paler than base ; lateral feather with outer web 

 edged broadly with paler or ochraceous white, rufous next the shaft; immacu- 

 late ; inner web with only 3 or 4 very narrow bars on terminal half. Head as 

 in the male, but vertex considerably tinged with rufous. 



Whole lower parts, including frontal and lateral regions of the head, contin- 

 uous, pure white ; breast with a very faint yellowish tinge; side of the breast 

 and sides with a few scattered minute elliptical, longitudinal flakes of rusty 

 more black on the shaft. Whole under surface of the wing white, as in the 

 male. 



Wing formula, 2, 34, 1. Wing, 7-00 ; tail, 4-70; tarsus, 1-40; middle toe, 

 90 ; culmen, 51. 



A Cuban female belonging to Mr. Lawrence is exactly similar. One in the 

 S. I. Collection, from Hayti (42420, Port an Prince, Jue 5th, 1860, A. C. 

 Younglove), differs only in less purely black bars, and in utter absence of the 

 moustache. A male from the same locality (43418) is like it in the last 

 respect. 



After having carefully examined quite a large series of Tinnuncules from 

 Cuba and San Domingo, I feel compelled to recognize two distinct species, 

 of which the present is presented as new although it has frequently been no- 

 ticed ; but only, however, in connection with the sparveroides, with which it has 

 been confounded. The diagnosis will I hope sufficiently explain my reasons 

 for separating these two birds. 



Differential Characters of American Species o/Tixnunculus. 



A. Breast, sides and lining of the wing spotted with black ; under surface of 

 primaries transversely barred with white and dusky. No conspicuous 

 white superciliary stripe. (1. Sparvcrms.) 



a. Head above and wings fine bluish ash ; one (outer) tail-feather only va- 

 riegated. 



1. Vertex with a conspicuous patch of rufous. Male. Black zone of tail 

 one inch in width ; breast strongly tinged with reddish ochraceous; 

 spots of black on breast circular. Female. Above, ful vous-mf ous ; 

 whole breast and sides with longitudinal dashes of a lighter tint of the 

 same. var. sparverius.* 



H. Vertex without more than a trace of rufous. Male. Black zone of tail 

 60 of an inch in width ; beneath, continuous dull white, with elliptical 



* Fatco sparverius, Linn. Syst. Nat. 176(3, 128. Tinn. sparverius, Vieill. Tinnunculus pha-

 ama northward ; not in W. Ind. nor S. Am.)
