16. SiGMODTJS MENTALIS, Sp. n. 



From Sassa, October. Having compared Mr. Bohndorff's spe- 

 cimens with S. rujiventris in the British Museum from Gaboon, I 

 find that the former may always be distinguished by the smaller 

 grey spot on the chin. It is strictly confined to the base of the 

 latter, whereas in S. rujiventris the grey spot on the throat is 

 much more extended, occupying the whole chin and part of the 

 upper throat as well. 



Adult. Greneral colour above black with a greenish gloss; wing- 

 coverts like the back ; quills black, externally greenish black like 

 the back ; tail black with a greenish gloss, and ribbed with dusky 

 cross-bars under certain lights ; round the hind neck a black 

 collar, uniting with the black throat ; entire head and nape 

 blue-grey, pearly grey or white on the lores and round the eye ; 

 cheeks, ear-coverts, and base of chin blue-grey ; remainder of 

 chin, throat, and sides of neck black ; fore neck and chest white ; 

 remainder of under surface pale cinnamon-brown ; sides of upper 

 breast, axillaries, and under wing-coverts greenish black ; quills 

 below black, all but the first primary and the inner secondaries 

 with a large white spot on the inner web. Total length 8*3 

 inches, culmen 0'85, wing 455, tail 3'2, tarsus 0*85.
