14 L. A. Jagerskiold. 



99. Pelicanus onocrotalus L. *. This pelican was not very 

 common along the White River. We only now and then noted 

 some few specimens of it. 



100. Pelecanus rufescens Gm. f. Single specimens and small 

 flocks of this bird were very common on the White River. 

 Though they were as a rule rather shy, I shot many of them. 



101. Gelochelidon nilotica (Hasselqu.) f . (--= Sterna anglica). 

 The "gullbilled tern" was observed several times near Khartum. 

 On the 5 th of April I shot a specimen in full summer dress near 

 el Geteina (about 46 miles south of Omdurman). 



102. Sterna caspia Pall. t. Observed near Khartum in 

 February. On the 4 th of April I shot a specimen not far from 

 el Gerassi. 



103. Hydrochelidon hybrida (Pall.). I shot an old. bird in 

 full winter dress in the swamps some few miles north of Kaka 

 on the 13 th of March. 



104. Rhynchops flavirostris Vieill. Now and then a big flock 

 of this interesting bird was seen, but on our way southwards 

 not until we reached Shellal Gebelein (on the 15 th of February). 

 But on our way northwards we found, on one of the last clays 

 of April on some sandbanks in the 6 th cataract, incubated eggs 

 which doubtless belonged to this species. Near their nests the 

 Rhynchops occurred single or in pairs. There they were not 

 at all shy but pursued the intruder with piercing cries in the 

 ordinary way of terns. For the rest they were wary and diffi- 

 cult enough to shoot. 



105. Chenalopex aegyptiacus (L.). Exceedingly common in 

 the parts of the country visited by us. In February the males 

 were moulting and we shot lots of them out of the flocks, whicl 

 could not escape our fast sailing nuggers. At that time ther 

 were also many females with halfgrown young ones to be seei 

 probably late broods. 



In April and May all the Nile-geese appeared by pairs, an( 

 one of the very latest days of April I shot, near the sixth cat* 

 ract, a newly hatched dunling, probably one of the first ones oi 

 the year.
