 cies was shot at our first nightstation not far from Grebel Auli 

 as well as at our farthest station south of Kaka. 



48. Lybius vieilloti (Leach). Shot near our farthest station 

 south of Kaka and in one or two places between that spot and 

 Goz Abu-Gomr. 



49. Mesopicus goertae (St. Mull.). Not uncommon in the 

 acacia brushwood. We met it even north of Ed Dueim on the 

 west bank of the river and now and then all the way between 

 there and the limit of our journey, where it was also shot. 



Of the four skins that were preserved during our Expedi- 

 tion one belongs to the subspecies Mesopicus goertae abessinicus 

 Rohw., viz an adult $ shot north of ed Dueim (N:o 421 of the 

 Cairo collection) and three to the subspecies centralis Rchw viz 

 two <? &, one young and one adult (the former has hardly any 

 trace of yellow on the belly) belonging to the Cairo museum 

 (N:o 420 & 422) and one <? in the collection of the Upsala 

 Museum. 



50. Dendromus nubicus (GrM.) smc. Shot near our farthest 

 station south of Kaka. 



One of the two females that were skinned has the crown 

 as usual black with rounded white spots, the other has the 

 crown of a sooty black with a few intermixed red feathers 

 among the black ones. This latter one has the malar-stripes 

 black and not red as in the males. 



51. Dendropicus obsoletus (Wagl.). smc. A female specimen 

 of this bird was shot near our southernmost station. Total 

 length about 138 mm. 



52. Palaeornis cubicularis (Hasselqu.). Not uncommon in 

 Hit' dense woods along the White River from Abba Island south- 

 wards. In the middle of February some Shilluks near G-ebelein 

 offered us some little more than halfgrown young ones of this 

 species.
