Acrocephalus baeticatus. The second was collected by C. H. B. Grant in Inbambane, 

 Mozambique. Without examination of the wing Acrocephalus baeticatus and 

 Calamocichla ziduensis resemble eaeh other far more than Ph/lloMrephus 

 strepitans and Calamocichla parva. The coloratiou and size of tlie bill arc 

 absolutel)' the same in both species. 



This new form is intermediate between C. leptorh/ncha and C. gracilirostris. 

 It has the small size of the former, bnt the coloration of the latter. The lores 

 are pure white, and the white is continued above the eye as in ffi-acil/rost>-is and 

 cunenensis, not slaty whitish as in leptorhyncha. The first primary is shorter 

 than in leptorhijncha and narrowed iu its terminal half It is a little less than 

 half of the second.

This bird is distributed from South Mozambique to Zaluland, and probably 

 to Natal, east of the Drakensberg Mountains, where it may replace C. gi-acilirostris. 

 I have seen many specimens of true c/racilirosfris from Newcastle, west of the 

 Drakensberg Range, but none from the coast regions of Natal. 



Calamocichla gracilirostris Hartl. 



Ciilamolwrpe (jraciliroslris Hartl., Ihis 18C4. p. 348 [Natal]. 



Above russet or fulvous brown, brighter on the rump, upper tail-coverts, and 

 edges of wings, below nearly white, slightly washed with yellowish buff on the 

 flanks. Lores and eye-streak white. 



Bnt for the pure white lores and eye-streak this species resembles very much 

 lighter specimens of C. leptorhijncha and the rufons dress of C. brevipennis, but 

 gracilirostris and zuluensis are distinguished from all other species of Calamocichla 

 by the shape of the first primary, >which is narrowed in its terminal part, and 

 somewhat pointed. It is somewhat less in length than half the second. 



The bill is not quite so broad as in most of the other species. 



This species never gets a grey dress, such as all the West African forms 

 of Calamocichla , as well us jachsoi/i, acquire at a certain season. 



It is of far less wide distribution than is stated by Seebohm, Cat. Birds, 

 vol. vii. p. 122, Reiclienow, Vdgel Africas, iii. p. 583, W. L. Sclater, Stark's 

 Birds of South Africa, vol. ii. p. 102, all these authors having accepted as correct 

 the statements by various authors who recorded other species of Calamocichla 

 under this name. 



It is distributed over South Africa from Capetown northwards to Omam- 

 bonde, near Otavi, in the west, and to South Transvaal and Western Natal iu 

 the east, that means high up the Orange River system. Bnt it does not appear 

 to occur in the lower Limpopo River,* nor in the coast region of Natal, east of 

 the Drakensberg Range, from where 1 have not seen a single specimen, and 

 wbere it may be replaced by the similar bnt much smaller C. zuluensis. 



As, however, I only know two specimens of G. zuluensis, the task to 

 clear up this question must be left to our friends of the South African Ornitho- 

 logists' Union. 



* From the wliolc Limpopo system I have seen only one small specimen from the Matlabas River,
