their noise ceased and the birds remained silent and 

 absolutely motionless. The Crowned Hornbill {Loi^hoceros 

 melanoleucus) was often seen, flying in large parties 

 from tree to tree. The Grey Louries, or Plantain-eaters 

 [Schizorhis concolor), were usually in pairs ; their variety 

 of cries and calls was surprising*. They had the Wood- 

 pecker-like habit of flying- from the top of one tree to 

 the lowest branches of the next, which they immediately 

 ascended, hopping up from bough to bough with rapidity. 

 Rollers, both Goracias caudatus and C mosamhicus, were 

 also often seen, likewise another Roller, not identified, but 

 probably G. spatulatus. Motacilla vidua was abundant 

 about the rapids, and also M. capensis. Merops hullockoides 

 and M. nuhicoides were seen every day. Both these lovely 

 Bee-eaters differed somewhat in habits from M. apiaster. 

 They were never seen flying round with the swallow-like 

 flight of the last named. The first behaved more like a 

 Chat, flying from bush to bush : the second like the 

 Spotted riycatcher, flying out to take an insect and 

 returning to its perch. 



Mr. Trevor-Battye observed that he did not propose to 

 say more of the many other interesting birds seen in this 

 region, as a good many of them had been already referred 

 to by Mr. W. L. Sclater in his paper on the birds of the 

 Victoria Palls (cf. Ibis, 1905, p. 106). He would therefore 

 turn to some of the birds seen on the river itself. The African 

 Pochard {Nyroca erythrophthal'ma) was in considerable num- 

 bers on the extensive sandbanks, which were also the resort 

 of many striking wading birds. The Sacred Ibis {Ihis 

 cetJiiopica), generally in pairs, sometimes in small com- 

 panies, was always one of the least shy, feeding to the last 

 moment, and reluctantly rising on the approach of the 

 canoes to fly round close overhead and settle again at 

 about the same spot. Two migrants, the Grreenshank 

 {Glottis nebularius) and the Common Sandpiper {Tringoides 

 hypoleucus), were noticed, while the White Stork (Giconia 

 alha) had not yet left on September 26th. The Marabou 

 Stork {Leptoptilus crumeniferus) was seen several times on 

 the open plain. A Pratincole [Olareola pratincola, or,
