Sharpe, Birds S. Afr. p. 110; — Boc. Orn. d'Aug. p. 97. 

 An adult female. 



*17. Ceryle maxima (Pall.). 

 Sharpe, Birds S. Afr. p. Ill; — Boc. Orn. d'Ang. p. 98. 

 An adult female. 



*18. Halcyon semicoerulea (Forsk.). 

 Sharpe, Birds S. Afr. p. 114; — Boc. Orn. d'Aug. p. 102. 



Two adult and two immature specimens. All four differ 

 from any other specimen of this species from more nor- 

 thern parts of Africa , especially by the gray color on 

 head and neck, which is not tinged with fulvous, by the 

 deep, nearly purplish blue on back, wings and tail, with- 

 out any greenish tinge, and by the very pale rusty color 

 on abdomen and under tail-coverts , while those parts are 

 reddish brown in all the birds from more northern localities. 



Iris brown, bill red, feet dull red. 



19. Halcyon cy an oleuc a ( Vieill.). — Four males. 

 *20. Lophoceros alboterminatus, n. sp. 



An adult male and two adult females , all three collected 

 in February. 



Adult male: Entirely similar to L. melanoleucus , as 

 far as I can judge from a comparison with the descrip- 

 tions of the latter, which is wanting in our collections; 

 but differing constantly from it by its centre pair of 

 tail-feathers being tipped with white in the 

 same degree as the outermost pair. In looking 

 through the rich literature of L. melanoleucus, I find only 

 one place (Boehm, J. f. 0. 1883, p. 168), where white- 

 tipped centre tail-feathers are mentioned J ). Wing 25,4 cm. 



1) Professor Barboza du Bocage kindly informed me that in all the 8 spe- 

 cimens of L. melanoleucus at his disposal the innermost pair of tail-feathers 

 is entirely black.
