them is (vcc from feathers for a couple of millimeters. There is 

 no projecting ridge or fold above them such as occurs in many 

 Mniotiltida*. In .' j and Witro* s the feathers come 



dose up to the posterior end of the nostril. 



rhe tongue ends in two points, one on each side; 

 there is a series of fine tooth or serrations mi each side, each 

 larger than its proximal neighbor, so that tho terminal 

 th is the largest. Sometimes the two terminal tooth on each 

 side are of equal site. This sort of a tongue occurs in many Passer- 

 ine birds which have no dose relationship, as the Catbird and the 

 Scarlet Tanager, It is not therefore in any way distinctive 



- i Phe head is fnll\ feathered with no special apteria 

 nor is there any unusual arrangement of feathers in longitudinal 

 series Tho upper cervical tract is narrow at tlrst but becomes 

 broader and more densely feathered between the shoulders and then 

 becomes narrow again before joining the dorsal tract. This enlarge- 

 ment of the cervical tract is the only characteristic feature of the 

 leneral pterylosis, It has not been reported for any other Passer- 

 ine bird sv> far as 1 know, but a somewhat similar arrangement ts 

 found in the kingfishers. Tho cervical tract anterior and posterior 

 to this enlargement is. in R : .-.\\ only three or tour feathers 



« tde but the enlargement b sue feathers wide. Tho rhombic dorsal 

 v •- w oil-marked and symmetrical and resembles that of 



■ an J. many other Tassoivs. The pterylosis 



surface shows no peculiarities save that the ventral 

 traots air unusually short, narrow and ill-defined. Tho primaries 

 rather short and the secondaries lone, giving the wine the 

 short, rounded shape characteristic of the genus. Tho really 

 remarkable fact here is the shortness of the eighth and ninth pri- 

 maries. In the Mniotiltuhv (with I \ and in . 

 tanagers, the eighth primary is one of the . - and tho ninth 

 • tlo shorter and is longer than tho fourth, but in . : : .W<r 

 tho eighth and ninth primaries are tho s: and tho ninth
