inches long and almost twice as large as the other. Their colors have faded, 

 but in a proper light the evidence of the spots on the body is obtained, and 

 those on the head are quite distinct in the adult, but in the young the spots 

 of the body have not been found. 



The species appears to be readily distinguished from any hitherto described 

 by the system of coloration. 



By special permission of the Academy, a paper was presented and 

 referred to a Committee. The latter having made a favorable report, 

 the paper was ordered to be published, as follows : 



Descriptions of four new Species of BIRDS from the Isthmus of Panama, 



New Granada. 



BY GEO. N. LAWRENCE. 



1. Tachyphonus rubrifrons. 



Tachyphonus xanthopygius, Lawr., nee Scl. Ann. Lye. N. Y. vol. vii. p. 

 331. 



Male. Front and part of crown dull red ; back part of crown, hind neck 

 and upper part of back of a slaty brownish black ; hind neck just tinged with 

 yellowish green : lower part of back and rump bright lemon yellow ; upper 

 tail coverts and tail brownish black, the former edged with dull greenish yel- 

 low ; wing coverts black, the middle and larger with lighter or slaty grey edg- 

 ings ; quills brownish black ; under plumage plumbeous grey, the feathers 

 of the throat with their centres lighter grey ; the abdomen with a slight 

 wash of greenish yellow ; the under tail coverts margined with greenish yel- 

 low ; axillars and under lining of wings white ; irides reddish brown ; bill 

 and feet black. 



Length (measured fresh) 6 J in. ; wing 3| ; tail 2f ; bill 1^ ; tarsi f. 



Habitat. Line of the Pan. R. Road, near Lion Hill Station. 



The female is rather smaller than the male, but the general plumage is 

 much the same ; it is without the red front and has more of the yellowish 

 tinge on the plumage. 



Allied to T. xanthopygius, Scl. The females appear to closely resemble each 

 other, but the males differ much in color and markings, xanthopygius being 

 black below as well as above, with a scarlet post-ocular stripe and bright yel- 

 low shoulders ; in my species the shoulders are black, it is without the red 

 stripe behind the eye, and the colors of the general plumage are much as in 

 the female. 



The red on the forehead of the male extends back for about half the extent 

 of the crown, where it is rounding in form ; in the single specimen of the 

 male the red spot is rather dull, but it may be brighter in other or older indi- 

 viduals, possibly as bright as the scarlet stripe in xanthopygius. 



The first specimen I received of this species was marked as a male, which 

 it probably is, but as it answered to the description of the female of T. utin- 

 thropygius, I put it in rny Cat. of Pan. Birds, as that species, supposing it to 

 be young and still in the plumage of the female. I have since received the 

 male described above, and two females. 



2. Anthds (Notiocorys) parvus. 



Anthus rufus, Law., nee. Gm. Ann. Lye. N. Y. vol. vii. p. 322. 

 Male. Upper plumage dark brown, the feathers margined with pale ful- 

 vous, the lighter margins most conspicuous on the hind neck ; outer tail 

 feather white, with a portion of the margin of the inner web at the base 

 brown, the next feather white with the margin of the inner web brown almost 

 to the end, the other tail feathers brown ; wing coverts brown wilh pale ful- 

 vous margins ; quills brown with very faint paler edgings ; under plumage
