Bill. Wing. Tail. Tarsus. 



P. tricolor. 

 Male, from Landana, Congo .... -60 3-75 3-20 -90 



I may mention that the above lists comprise specimens of 

 P. nigricans killed in January, May, June, July, August, 

 and October — and of P. layardi in February, March, June, 

 July, and September — showing that the differences between 

 these two species are not merely seasonal. — J. H. G.] 



327. Cratbropus jardinii. Smith. Jardine's Babbles. 



Male, Rustenburg, May 29th. Irides with a crimson outer 

 ring and an orange inner ring ; bill black ; tarsi and feet 

 dark ash- colour. 



Female, Rustenburg, May 29th. Resembling the male, but 

 with the outer ring of the irides scarlet. 



This Babbler is common about the mountains, where it is 

 found in companies. 



Crateropus bicolor, Jardine. Southern Pied Babbler. 



Male, near Rustenburg, June 24th. Irides orange, fading 

 into light yellow at the outer edge ; bill black, tarsi and feet 

 dark dusky brown. 



Female, near Rustenburg, June 26th. Irides brownish 

 orange ; bill, tarsi, and feet as in the male. 



This is a much scarcer species than the preceding one, and 

 also much more wary. I met with two or three companies 

 near the Eland's river, a tributary of the Crocodile river ; 

 but it was with some difficulty that I shot the two speci- 

 mens sent. 



MoNTicoLA BREviPES, Watcrh. Short-footed Rock -Thrush. 

 Male adidt. Irides dusky ; bill, tarsi, and feet dingy black. 

 This species is widely distributed about the mountains, but 

 is not very common. 



CossYPHA HUMERALis, Smith. White-shouldercd Chat- 

 Thrush. 



The bird sent was killed in February by my brother at Rus- 



from the Pangani River, in the same district, should be so much smaller 

 than the next specimen, which is said to have been obtained at Zanzibar 

 itself on the Zanzibar island.
