One of the most remarkable birds obtained was Lanius 
guhernator 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 pointed out that the 
species had a distinct autumn dress before the moult, which

moult were at first greyish, and assumed immediately, by 
change of colour, the characteristic dark background with 
white spots.
