136. Nigrita canicapilla, (Strickland.) 



Aethiops canicapillus, Strick., Proc. Zool. Soc. London, 1841, p. 30. 

 Fraser, Zool. Typ. Birds, pi. 48. 



Specimens labelled as males only from the Camma and Moonda. The adult 

 male is described and figured as above. 



137. Nigrita ldteifrons, J. and E. Verreaux. 



Nigrita luteifrons, Verr. Rev. et Mag. Zool., 1851, p. 420. 



Strictly congeric with the preceding, but smaller. All the specimens in the 

 present collection are labelled as males, which in its adult plumage is described 

 by Messrs. Verreaux as above. 



Young 5 Entire plumage bluish cinereous or plumbeous, paler on the 

 under parts of the body. Wings and tail black, under tail coverts tinged with 

 pale rufous. No trace of the black of the under parts of the body which is in 

 the adult bird. From the Camma. 



138. Nigrita fdsconota, Fraser. 



Nigrita fusconota, Fras. Proc. Zool. Soc, London, 1842, p. 145. 



Fraser, Zool. Typ. Birds, pi. 49. 



Some exercise of the imagination is required in rating this bird in the same 

 genus as the two preceding. The male is figured as above, and that sex only 

 is represented in the present collection from the Camma. A single specimen 

 was formerly received from the Moonda. 



This bird probably belongs to a group of which, perhaps, Estrelda is the type, 

 and seems to represent a subgenus, or perhaps a genus, certainly quite dis- 

 tinct from Nigrita. 



139. Nigrita bicolor, (Hartlaub.) 



Pytelia bicolor, Hartlaub, Cat. Bremen Mus., p. 76. 

 Nigrita bicolor, Sclater Jard. Contr. 1852, p. 34, pi. 83. 



Scarcely of this genus, but more nearly related to the immediately preced- 

 ing. This species is in Dr. MacDowell's collection from St. Paul's river, and 

 it has now been received in several of Mr. Duchaillu's collections. 



Specimens labelled as of both sexes are much alike, and the adult bird is 

 intended to be represented in the plate above cited, but the bill is given too 

 short and entirely erroneously. The bill is somewhat lengthened, with the 

 commissure curved. 



Young <$ Upper parts dull ashy brown, darker on the rump and upper 

 tail coverts, neck before and breast dull reddish ashy brown, abdomen and 

 under tail coverts clear ferruginous. Wings and tail brownish black. From 

 the Camma and formerly from the Moonda. 



140. Sycobius cristatus (Vieillot.) 



Malimbus cristatus, Vieill. 



Tanagra malembica, Daud. Ann. Mus., Paris, ii. p. 148, pi. 10. 

 "Sycobius nigrifrons, Temm." Hartl. Cat. Jour., 1855, p. 356. 

 Shaw Nat. Misc. pi. 581, Vieill. Ois. Chant, pi. 42. 



Several specimens of both sexes from the Camma and formerly from the 

 Muni. 



141. Sycobius malimbus, (Temminck.) 



Textor malimbus, Temm. 



Ploceus rubricollis, Swains. An. Menag., p. 306. 

 Malimbus cristatus, Vieill. (female). 

 Vieill. Ois. chant, pi. 43. 



One specimen only from the Camma, and another was formerly received from 

 Cape Lopez. Appears to be a distinct species and is at least not identical with 

 Euplectes rufovelatus, Fraser, Zool. Typ. pi. 46. 



1859.]
