b. Breast light sulphur-yellow, slightly darkening in older birds, but always 

 distinctly yellow ; light grey on the head, verging gradually into light 

 olive-greenish, becoming more sulphur-yellow on the rump and upper tail 

 coverts -. smithi. 



186A. LANIUS LUEBBERTI Echw. 



Eeichenow (Vog. Afr. ii. p. 619) describes a new Shrike from 

 Brakwater in Damaralarid as follows : 



" Above throughout pale grey, a black band from the base of the 

 bill through the eye and ear coverts, above which is a plainly marked 

 white eyebrow ; wing coverts and quills black, primaries white at the 

 base, inner primaries and secondaries with narrow white tips ; below 

 white, breast and abdomen tinged with salmon ; under-wing coverts 

 white, those of the primaries grey, middle tail feathers black with 

 narrow white tips, others with base and tip white, outer pair pure 

 white ; bill and feet black ; length, 8-25 ; wing, 4-5 ; tail, 4'0." 



It appears to be closely related to L. minor. 



195A. DRYOSCOPUS CUBLA HAMATUS Hartl. 



Eeichenow (Vog. Afr. ii. p. 594) distinguishes the tropical form of 

 the Puff-back Shrike under the above name. The males, apparently, 

 are identical, but the female can be distinguished by the greyer 

 tinge of rump, and is without any trace of the olive-green shade 

 present in the typical form. According to Eeichenow this form occurs 

 from East Africa to Angola and North Damaraland. 



I am not able to sustain or otherwise this subspecies with the 

 specimens at my disposal. 



196. DRYOSCOPUS RUFIVENTRIS (Shaw). 



This species should be referred to under Shaw r 's name as above, 

 which was founded on " le Boubou " of Levaillant. 



196A. DRYOSCOPUS RUFIVENTRIS HYBRIDUS Neum. 



Eeichenow (Vog. Afr. ii. p. 583) distinguishes a northern sub- 

 species of the Greater Puff-back Shrike by the pale ochreous colour 

 of the whole of the under-parts from the crop downwards. 



It takes the place of the typical subspecies from the Transvaal 

 northwards to the Zambesi and beyond to German East Africa. 



204. LANIARIUS MARAISI Scl. f. 



Dr. Eeichenow believes that this species is founded on a young 

 bird of L. ntbiginosus ; in my original description I stated that I
