Macrodipteryx vexillarius fulleborni (Rchw.). — Rchw, II. p. 372. 

 1 (5 ad. 8. 7., 1 djuv. 11. 7.; Mount Elgon. 



The two specimens of this race were shot by Dr. G. Lind- 

 blom in the Kitosh country on South Elgon. 



The young bird is exactly like the old one in plumage, 

 but the elongated rectrices have not yet attained the length of 

 those of the old bird but extend only 5 cm. beyond the tip of 

 the tail. 



Wing 220 mm., ad. 195 mm. juv; tarsus 25, 22 mm. 



Irides dark-brown; bill dark greyish brown; legs of full- 

 grown, brownish grey, of young bird, brownish yellow. 



Hirundinidae.

A large flock of these bird were seen flying about a sand- 

 bank on the edge of the forest. Here and there the commenced 

 excavations for their future dwellings were seen. It is possible 

 that the holes in the sandbank, leading into the narrow passages 

 are not dug by these swallows, for I never saw them engaged 

 in the work of digging although they flew backwards and forwards in 

 front of them and at times sat resting in the mouths of the 

 passages. 



Wing 98 mm, tarsus 10 mm. 



Irides dark-brown; bill dark- brown (brownish black); legs 

 black. 



In the Royal Natural History Museum in Stockholm there 

 are specimens of R. p. minor from Kilimandjaro which are lighter 

 and paler than ducis, but according toSclater & M.-Pread 

 (Ibis 1918, p. 715) minor occurs in Abyssinia and the upper 

 Blue Nile. The question is then, whether the individuals esta- 

 blished by S j s t e d t are really minor and that the distribution 

 of that race thus enters the region for ducis (which is hardly 

 probable) or are only paler specimens of ducis. 



Riparia cinda cincta (Bodd.). — Rchw. II. p. 394. 



2 (5(5 ad. 5. 5., 7. 5. Londiani, 7.500 ft. — 1 (5 ad. 14. 5; 

 2 66 juv. 26. 7. Soy 8.500 ft. 



In Londiani this swallow was abundant and was breeding 

 in a railway bank in the forests. At Soy, where the race was 

 also common, I saw them in the evenings flying in flocks around 

 some small pools of water in the grass-plains. In July the young
