55. Ridgtvay on Pachyrhamphus albinucha. 



[Note ou PachyrhamiTilms albinucha, Burmeister. By Robert Ridgway. 

 Proc. U.S. Nat. Mus. xiv. p. 479.] 



Mr. Ridgway lias made a very interesting discovery. In 

 the stores of the U.S. National Museum he lias found, a 

 specimen of the Pachyrhamphus albinucha of Burmeister, 

 described by that author in 1868 (P. Z. S. 1868, p. 635), 

 but since absolutely overlooked. This curious form has a 

 pycnaspidean tarsus, and must consequently belong to the 

 Cotingidse, being probably most nearly allied to Casiornis. 

 Mr. Ridgway proposes the new generic term Xenopsaris for 

 it. It is found, according to Dr. Burmeister, in the sedge of 

 tlie shores of the Rio de la Plata*.

Mr. Ridgway characterizes two new species of Thamno- 

 philus from specimens in the U.S. National Museum. These

 from Trinidad, the first apparently so.

* Since this notice was wi'itten we have observed that Dr. Cabanis 

 (Allg. deutsche Gesellsch. Berlin, Bericht ix. p. 4) has proposed another 

 generic term {Prospoietus) for the same bird, which he considers to belong 

 to the Tyrannidse, near ScrpopJint/n.
