Mr. R. B. Sharpe's Catalogue of Accipitres. 487 



p. 458, as having been recently described by the late Pro- 

 fessor Sundevall, under the title of Plangus neoycBus, in CEf . 

 k. Vet. Akad. Forh. 1874, No. 2, p. 28. I have no knowledge 

 of this species beyond what is contained in Professor Sunde- 

 valFs notice of it in the above-named periodical, from which 

 I transcribe the following particulars : — 



"Plangus, n. gen. plumis occipitis paucis oblongis, lon- 

 gioribus, cristam formantibus ornatus. Cauda longior (ala 

 cubitali antica paullo brevior). — Sp. unica cognita, ex Brasilia, 

 magna, Aquilse sequalis, prsecedentibus'^ affinis; a Morphno 

 prsesertim naribus oblongis, longitudinalibus distincta. Ala 

 magna, lata et longa : quiescens, apice caudse paullo brevior, 

 pennis cubiti anticis | alae fere attingentibus. Tarsus \ alse 

 cub : s sequalis ; digiti longiusculi, fortes * -J^- ^ -J?- 



" Plangus neogaus, nob., fuscus, gastrseo toto albo, maculis 

 rachidum angustis, f uscis vario, remigibus rectricibusque extus 

 fusco-cinereis, maculis minutis, fuscis, crebre variis. Fascia 

 caudse nulla. Ala 580 mm. Specimen unicum in Brasilia, 

 prope Caldas occisum, anno 1855 attulit et Musseo Stockhol- 

 miensi donavit cl. G. A. Lindberg." 



The genus Urubitinga, to which I next propose to refer, 

 should, I think, be restricted, as I have already mentioned, 

 to two species, U. zormra and XJ. antkracina, unless JJ. gund- 

 lachi be admitted as a third^ and considered specifically dis- 

 tinct from U. anthracina. 



I have not much to add to Mr. Sharpens account of these 

 species ; but it may be desirable to note that both in U. zonura 

 and in U. anthracina the iris is bi^own. 



I may also mention that a specimen of U. anthracina from 

 the Island of St. Vincent is now living in the Gardens of the 

 Zoological Society ; this example was in immature dress when 

 it arrived at the Gardens, but is now in full plumage, with 

 the exception of a slight tinge of rufous brown on the back 

 and sides of the head, and also on the tertials. I am indebted 

 to the kindness of Mr. Bartlett for the following note respect- 

 ing the moulting of this specimen, which I here insert, as it 



* The species here referred to are Urubitinga zormra and Busarelhis 

 nigricoUis.
