Mr. Swainson on several new groups in Ornithology/. 359, 



Ala mediocresy sub-attenuata ; remigibus 1«« et ^^ gradatis^ 3'w, 



4^^, et bt^fere aqualibus, longissimis, 

 Cauda mediocrisy aqualis. 

 Pedes graciles, breves; tarsis squamis anterioribus divisis^ late* 



ralibus nullis. 



Bill moderate, depressed, tip of the superior mandible hooked. 



Wings moderate, rather pointed ; the first and second quill gra- 

 duated, the third, fourth, and fifth nearly equal and longest. 

 Tail moderate, even. Feet short, slender, the anterior scales 

 divided ; lateral scales none. 



Type. Muscipeta barbata. Sw., Zool, 111. 2. pi. 116. 



This group, containing numerous species, leads immediately 

 to the Tyrant Flycatchers, Some few species will, of course, 

 present deviations from these characters^ yet the comparative 

 length of the two first quill feathers separates Tyrannula from all 

 the European, African, and Oriental groups; and confines tha 

 genus to the new world. 



CULICIVORA. 



Rostrum breve. 



Ala brevissima, rotundata ; remigibus l*"^ et 2^^^ gradatis^ 3'»«, 



4'«, 5^^, &a^ et 7 f"^ fere aqualibus^ longissimis. 

 Cauda gracilis^ elongata^ gradata. 

 Pedes gracileSj longi^ tarsis squamis lateralibus frequentibus. 



Bill short. Wings very short, rounded ; the first and second 

 quills graduated; third, fourth, fifth, sixth, and seventh, nearly 

 equal and longest. Tail slender, lengthened and graduated. 

 Feet long, slender ; lateral scales numerous. 



Type. Muscicapa stenura. Temm., PI. col. pi. 167. f. 3. 



I possess two other undescribed species of this genus. The 

 length of the legs indicates some peculiar economy, of which, at 

 present, we are ignorant. The bill does not materially differ 

 from that of the last genus, otherwise than in the tip not being 

 so abruptly bent.
