116 Captain G. Shelley on 



by Dr. Kirk from East Africa. The collection which con- 

 tained them includes many other interesting forms, which I 

 shall refer to in a future paper. 



1. Parus albiventris, sp. n. 



General plumage black; median wing- coverts white; greater 

 wing-coverts and the quills edged with white on their outer 

 webs ; the white edges of the inner primaries and outer secon- 

 daries shaded with ashy olive ; primary-coverts with almost 

 obsolete pale edges ; the outer tail-feathers with the greater 

 portion of the exterior web and the euds of the feathers 

 white, the next pair having the end half of the outer webs 

 very narrowly edged with white ; centre of the chest, abdo- 

 men, thighs, and under tail-coverts white ; under wing-coverts 

 white ; inner margins of the quills cream- colour ; bill black ; 

 legs slate-colour. Total length 7' 75 inches, culmen '4, wing 

 3-3, tail 2-75, tarsus '8. 



Hab. Ugogo. 



This species, sent home by Dr. Kirk, is represented by two 

 specimens, probably a male and a female, the latter of which 

 I have here described. The other agrees well in its measure- 

 ments, but is a trifle brighter in plumage, and the ashy-olive 

 shade on some of the quills inclines rather to grey. 



2. COSMOPSARUS UNICOLOR, Sp. n. 



General colouring ashy brown ; a triangular patch in front 

 of the eyes almost black ; wings and tail glossed with metallic 

 green, and with numerous narrow obsolete bars, only visible 

 in certain lights ; wing-coverts but slightly glossed with 

 bronzy green ; the green gloss on the secondaries rather 

 stronger ; primaries nearly black, with the green gloss gene- 

 rally of a deeper shade than on the remainder of the wing ; 

 tail deep metallic green, or brownish black very strongly 

 glossed with metallic green, and with numerous narrow black 

 obsolete bars, more distinct than on the wing-feathers ; under 

 surface of the tail black ; bill and legs black. Total length 

 12 inches, culmen -7, wing 5-1, tail 7'3, tarsus 1'35. 



Hab. Ugogo. 



Three specimens, all in identical plumage.
