There are at least three birds of this group which arc in their 

 adult plumage Blaty-black or blackish, with a white baracroM the 

 tail. The tir>t of these and largest in siae i> the Falco urubitinga 

 of the older authors. Lesson in 1839 proposed to convert the term 

 Urubitinga into a generic name, and it was so adopted bj Lafres- 

 naye in L842, before the creation ofCabanis'a genus Hypomorpkmu 

 for the same type. Sec .M. de Lafreanaye's remarks on tin- subject 

 in the 'Revue Zoologique' for 1848, p. 240. With regard to the 



specific name to be employed for this bird we ca I use Brisson'i 



" brasitiensu" as is done in Strickland's 'Ornithological Synonyms,' 

 because Brisson's* names are not to be employed in a binominal 

 system of nomenclature. Nor i> it proper to adopt Illiger's .Ms. 

 term " longipee," as proposed in I'rinee Bonaparte's ' Conspectu-,' 

 while there are nianv other names lor this bird already published. 

 So the earliest specific name available seems to be Shaw's tonunu 

 (Fafro eonurue, Shaw's Zool. vii. p. 62), and this species should 

 stand as Urubitinga tonura. It appears to have an extensive range, 

 extending from Paraguay, all over Bolivia, Peru, Brazil, Guiana and 

 New Granada into Southern Mexico, where specimens were obtained 

 by M. Salle (see P. Z. S. 1857, p. 227). 



The second allied species of Urubitinga is the " Fafro anthra- 

 cinus, Lieht. in Mus. Bcrol.," under which name it is described by 

 Nitzsch in a note to his * Pterylographie ' (p. S3). This is the 

 same as Dn Bus's Morpkrau mexicanus (Bull. Ac. Brux. 1847). 

 See M. de Lafrcsnaye's observations in the 'Revue Zoologique' for 

 18-18 (p. 240), where he clearly points out the differences between 

 this bird and the Urubitingd zouvra. The Urubitinga anthracina 

 inhabits the northern portion of South America, Guianat and New 

 Granada £, Guatemala and Southern Mexico§, where MM. Botteri 

 and Salle both procured it, and M. Du Ibis's types were collected. 

 The third species is Urubitinga schistaeea as characterised above, 

 which is distinguishable at once from the preceding by its inferior 

 size and narrower tail-band. The following diagnoses are sufficient 

 to point out the differences between these three species || : — 



1. U. zonura. Major, cauda dmridio baaaH rt wuargine apicaH 



a I bis. 



2. U. anthracina. Media, cauda fascia lata et margine apicali 



albix. 



3. U. schistaeea. Minor, caudat facia anguttaet margine apicaH 



ill his. 



Such are these birds in their adult plumage : in their immaturity 

 they are quite different. 1 have not yet seen tl iU.echi-
