superciliarj' region is entirely black ; thus one of the points marked 

 by du Bocage as differences between T. minutus and T. anchietce 

 is of no importance. The absence of black on the mantle, however, 

 separates T. anchicta' sufficiently ; and this separation is again sup- 

 ported by the geographical distribution of the two species. 



Hah. Anchieta"s Bush-8hrike was first discovered in Angola 

 (Pungo-Andongo), but has since been found on the east coast of 

 Africa, opposite Zanzibar. Thiis this species probably ranges from 

 Angola right across the continent to the Zanzibar coast.

Bill of Dryoscopus cubla. 



Bill considerably bent, hooked and notched ; the proportion of 

 height to breadth varying much even iu one and the same species, 

 e.g. iu D. cuhJa, leading thus to the broad-billed D. sabinei, for which 

 the generic term Chaunonotus was invented. Nostrils oval, in front of 

 a coriaceous groove, which is overgrown with little feathers ; nostrils 

 themselves exposed ; bristles weakly developed. Pirst jirimary be- 

 tween half and three quarters of the length of the next primarj'. 

 Wings rounded, fourth and seventh primaries forming the tip. Tail 

 rounded, equal to or slightly shorter than wings. Tarsus covered 



* Among the doubtful species belonging to this obscure and diiScult genus 

 may be mentioned the following : — 



Devoscopus somalicus. 



Lanius somalicus, Hartl. Ibis, 1859, p. 342 ; Finsch ^~ Hartl. Vdg. Ostafr. 



p. 3.33 (1870) ; Heuglin. Faun. roth. Meer. no. 125. 

 Dryoscopus somalicus, Hcvyl. Orn. N.O.-Afr. pp. 460, csvii. 



"Above fine black, excepting the middle of the back being transversely varie- 

 gated witb grey and wbitisb ; below white, without any rose-tint ; tail much 

 \\ke i\[a.{ oi L. minor. Hah. SomaU Land." 



If correctly described, this Dryoscopus would be distinct from the rest ; but as 

 we are informed that the only two birds obtained were " lost during a fight," 

 the species must have been described from memory.
