 type in form of wing, which has lirst three quills much gradated 

 and fifth longest, and it has the legs, feet and nails of the next sub- 

 genus, 



Digenea, mihi, 

 which diff^ers from Dlmorpha proper by having the wings shorter, 

 with the fifth or sixth quill longest, the legs and feet longer and 

 slenderer, and the nails less bent, but larger ; the thumb larger and 

 the nail cuneate. The types are tricolor and leucomelanura,

Passing next to the subgenus 



Synornis, 

 we have a medial Muscicapan wing, whereof the first quill is spurious, 

 the second long, and 3-4 longest. The bill is more exposed at its 

 base, the rictal and nareal hairs are shorter, and the legs and feet 

 are more ambulant, with smaller thumb and nails, neither slenderly 

 elongate nor shortly falcate. The type of this form is our Joulaimus, 

 but it is the species whereof the male seems to be Sykes's Saxicola 

 rubeculoides, and the female Gmelin's Muscicapa leucura. 



S.Joulaimus, mihi Above earthy brown, below diluted to luteous ; 



throat and breast bright rusty ; sides of head and neck dull slaty ; tail 

 black, with white lateral base. Female below void of the red colour, 

 being throughout sordid white. Length, 5| inches ; bill, -^-^ ; tail, 2 J ;
