and much shaded with green on the sides. Under coverts of the wings green- 

 ish yellow. Bill corneous, the margins white, tarsi light bluish. 



Female similar but smaller. 



Hub. Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu. 



Obs. This species much resembles in form and color T. ffularis, Horsfield, 

 from Java, but is much smaller and otherwise different. It also resembles T. 

 canicejjs, Lafres, (which seems to be Najwthera sulphurata, Miiller,) and is about 

 the same size. It is a very remarkable form for Western Africa. 



In color this bird appears to be similar to Dasycephala syndactyla, Swainson, 

 (which is described as 9| inches long,) but it has no syndactyle character, and is 

 much smaller. Several specimens are in the collection. 



7. Trichophorus notatus, nobis. 



Bill moderate, nearly straight ; wing with the fourth and fifth quills longest. 

 Tail rather long. 



Bhnensions. Total length (of skin) about 7^ inches, wing 3^, tail 3^ inches. 



Colors. Male. A spot of yellow in front of the eye. Entire upper parts 

 yellowish olive green, darker on the head ; wings and tail the same color as the 

 back, with the inner webs of the feathers dark reddish brown. Quills edged on 

 their inner webs with pale yellow, outer feathers of the tail with large spots of 

 pale yellow at their tips. Under parts bright yellow, tinged with green on the 

 sides. Bill corneous, edges of both mandibles white ; tarsi light colored. Un- 

 der wing coverts yellow. Female, similar but rather smaller. 



Hab. Moonda river, Western Africa. Discovered by Mr. P. B. Du Chaillu. 



Obs. Owing to evident difiSculties in determining the species of birds which 

 have been referred to the genus Tricophorus, we have invariably declined pre- 

 senting any as new in the various African collections that have come into our 

 hands. But the two birds that we now describe are so strongly marked, that 

 we have abandoned our previous custom. 



The present bird belongs to the same group as T. canicapillus, Hartlaub, cha- 

 racterized in some measure by the bill being straighter than usual in this genus. 

 It does not, however, closely resemble that species, nor any other known to us, 

 and is strongly marked by the bright yellow spot in front of the eye, which cha- 

 racter distinguishes it at once from T. eximius, Hartlaub (Cabanis Journal, 1855. 

 p. 356), and it is much smaller. Four specimens are in the collection. 



On motion of Dr. Rand, the Academy proceeded to an election for 

 Librarian to fill the vacancy caused by the resignation of Dr. \V . S. 

 Zantzinper. 



The Chair appointed Dr. Brinton and Mr. Schafhirt, Tellers. The 

 election having been held, the tellers reported that Dr. J. Aitken 

 Meigs had been unanimously elected. 



F.LECTION. 



Drs. Wm. Mayburry, Thos. George Morton, and George R. More- 

 house, of Philadelphia, and Mr. Alfred Monnier, of Camden, were 

 elected Members; and Mr. J. Barnard Davis, of Shelton, England, was 

 elected a Correspondent of the Academy.
