595. Cisticola erythrogenys djamdjamensis Neum. = Cisticola luguhris 



djamdjamensis. 



Cisticola erythrogenys djamdjamensis Neumann, Journ. f. Orn. 1904. p. 163 (Djamdjam) ; id., op. cit. 

 1906. p. 269. 



Type : ?, Abera in Djamdjam, 16.xii. 1900. Oscar Neumann leg. No. 429. 



After studying these Cisticolae with Dr. van Someren I have come to the 

 conclusion that erythrogenys is the non-breeding plumage of luguhris ! Therefore 

 erythrogenys becomes a synonym of luguhris and djamdjamensis a subspecies 

 of luguhris. 



596. Cisticola robusta schraderi Neum. = Cisticola rohusta schraderi. 



Cisticola rohusta schraderi Neumann, Journ. f. Orn. 1906. p. 265 (" Nord-Abyssinien "). 



Type: Senafe, N. Abyssinia, 7,500 feet, 10. i. 1903 (not 1902!). Gustav 

 Schrader leg. 



f 597. Cisticola blanfordi sobatensis Neum. = Cisticola luguhris marginata. 

 Cisticola blanfordi sobatensis Neumann, Dm. Monatsber. 1904. p. 164 (Sobat). 



Type : J, Diek, on the Akobo River, one of the source rivers of the Sobat, 

 28. V. 1901. Oscar Neumann leg. No. 1,255. 



Neumann {Journ. f. Orn. 1906, p. 270) declares, after comparing the type of 

 hlanfordi, that his sohatensis is the same as blanfordi. Sclater and Mackworth-Praed 

 {Ibis, 1918, p. 647) adopt the name marginata Heugl. for this form, treating it, 

 as Neumann did in 1906, as a subspecies of C. luguhris. I am convinced that 

 Neumann as well as Sclater and Praed were right in their conclusions, and that 

 therefore C. h. sobatensis is a synonym of C. I. marginata, described by Heuglin, 

 This, 1869, p. 94, pi. i. fig. 1, from the White Nile between Fashoda and'Lado. 



This form is closely allied to haematocephala, and it would be a great help 

 if the differences, in the various plumages, between marginata and haematocephala 

 (1868) were clearly described. 



598. Cisticola ansorgei Neum. = Cisticola suhruficapilla ansorgei. 



Cisticola ansorgei Neumann, Bull. B.O. Club, xvi. p. 114 (1906 — " Benguella "). 



Type: ^ ad., Caconda, Benguella, 7.ix.l904 (not " 2.ix. 1904 "). W. J. 

 Ansorge leg. No. 893. 



598 a. Cisticola idmiiens perpuUa subsp. nov. 



Type: (J ad., Bailundu country, Benguella, IS.viii. 1901. C. Hubert 

 Pemberton leg. 



Differs from C. tinniens tinniens in being darker. The crown is of a less 

 bright, darker brown, and the blackish streaks are, as a rule, less obvious ; the 

 edges to the feathers of the back are narrower, darker, and more brownish so 

 that the whole upperside looks much darker ; the margins of the tail-feathers 

 are of a less bright and darker brown, the tips of the lateral pairs havfe less 

 sharply defined black anteapical cross-bars. Underside of a duller, more greyish 

 less buffy-yellowish coloration. Wings : 2 cj, 60 and 61'5 ; 2 $, 54 and 65 mm!
