Hah. Panama, Turbo [Lieut. Michler ^ ^). 



The type of this species has been kindly sent to us from Philadelphia, it being the 

 property of the Academy of Natural Science of that city. It is in poor condition, the 

 bill being much injured. The species is closely allied to Thamnophilus nigriceps, Scl. 

 {cf. Cat. Birds Brit. Mus. xv. p. 194, t. 12), and indeed before we placed the types 

 together we were under the impression that they belonged to one species. Compared 

 with T. nigriceps the wings and tail of T. virgatus are clearer cinnamon, the shaft- 

 stripes of the head considerably wider, the head thus being not nearly so dark ; the 

 stripes, too, of the under surface are wider and more numerous on the abdomen instead 

 of being confined to the central portion ; the under surface of the wings and inner edge 

 of the quills are cinnamon and not fawn-colour, as in T. nigriceps. 



The two birds are peculiar in their style of plumage, and unlike any other members 

 of the genus Thamnophilus. In their striated head and neck they resemble T. bridgesi, 

 but that bird has no cinnamon colour in its plumage. 



The only known example of this bird is the type, which was obtained during Lieut. 

 Michler's Expedition to Darien. Cassin did not give it a name in his list of the birds, 

 but Mr. Lawrence described it in 1868.
