At Walembele, Colonel Northcott obtained Palceornis 

 docilis and Melittophagus pusillus. 



One of the most remarkable species exbibited was Lanius 

 gubernator, Hartl. J. f. O. 1882, p. 323, Taf. i. fig. 2, which 

 was previously known only from Equatorial Africa. 



Mr. J. L. Bonhote exhibited a series of adult skins of 

 the Red-throated Diver (Colymbus septentrionalis) showing 

 the various stages of the moult, and pointing out that the 

 species had a distinct autumn dress before the moult, which 

 was assumed by a regular abrasion during the latter end 

 of the breeding-season. From the immature specimens 

 Mr. Bonhote pointed out that they moulted straight into 

 their adult dress, probably during their second winter. 



Mr. Bonhote also exhibited two specimens in moult of the 

 Great Northern Diver {Colymbus glacialis), showing that in 

 this species the new feathers which grow at. the autumn 

 moult are at first greyish, and assume immediately, by 

 change of colour, the characteristic dark background with 

 white spots.
