Tijpe of S. nandensis. Differs from the above only in having the upper 

 half of the throat jet black, with the pale edges to the feathers confined to 

 the middle throat and inclining there to bright yellow spots. " Iris dull 

 crimson ; bill horn-blue, with the tip black ; feet flesh-colour." Total 

 length 5-5 inches, culmen 0-7, wing 3-15, tail 2-1, tarsus 0-95. 2 , 10. 4. 96, 

 Nandi (Jackson). 



The Black-cliinned Grej-backed Weaver inhabits Central 

 Equatorial Africa. 



The species is only known by the type discovered by Emin 

 at Buguera, close to Wadelai, an adult male, and by the type 

 of 8. nandensls, a female bird from Nandi, so it is highly 

 probable that they represent the two sexes of one species, as 

 Dr. Eeichenow has suggested (Vog. Afr. iii. p. 35) ; but as this 

 has yet to be proved I have treated them as subspecies. 



The measurement of the wing, in the type of S. mentalis, 

 as given by Hartlaub, appears to me to be an error, for I 

 think it should be the same as in 8. tefhronotus and 8. 

 nundt')i)>is.
