These measurements, and those of the preceding species, 

 may be compared with the tables of dimensions given at 

 pp. 152 and 150 of Anderssou's ' Birds of Damara Land.' 



The four specimens of P. erythropterus have the crown of 

 the head black, and the four of P. trnvirgatus have it brown, 

 showing the usual distinction between the two species in that 

 respect. — J. H. G.] 



332. Dryoscopus cubla (Shaw). South-African Puff- 

 Shrike. 



Male, Rustenburg, June 11th. Irides red. 



Female, Rustenburg, June 6th. Irides orange. 



Female, Rustenburg, August 9th. Irides dull crimson.

 and rich as that of the accompanying male, and the fawn- 

 colour of the underparts is more so ; the white bar on the 

 wing is as distinct in this female (which is probably quite an 



* [In Mr. Sharpe's 'Catalogue of African Birds/ 1871, this species is 

 referred to the genus Dryoscopus ; but it seems to me that it cannot be 

 generically separated from the succeeding species (atrococcitieus) , which 

 Mr, Sharpe, in the same work, refers to the genus Laniarius, — J. II. G.]
