there side by side. I trust that if an answer is forthcoming to this problem 
of distribution, measurements of the bill and tail, if not also other parts, 
will be given, for those of the wing alone do not afford an altogether satis- 
factory guide. Mr. C. H. B. Grant is misleading in stating that the 
difference lay in the wing alone. The two specimens on which “ maraisi ” 
was described are both old ones, as is shown by the development of the 
bill, yet in every respect they are much smaller than the average “ nasutus .”

At p. 273, Grant places Lophoceros damarensis in the synonymy of 
L. erythrorhynchus caffer* stating that, in his opinion, the types are 
albinistic individuals. This is not the case, for there are four specimens 
of this bird in the Transvaal Museum taken at Windhuk, Damaraland, 
which agree perfectly with Shelley’s description. This bird is apparently 
not a subspecies of L. erythrorhynchus , but more likely a very distinct 
species, and it is surely the height of arbitrary procedure to reject it on no 
better grounds than conjecture. 
At p. 283, Grant assumes, probably correctly, that the type of Irrisor 
erythrorhynchus was procured at Knysna and that /. viridis from east of 
the Sunday River is a synonym. The fauna of the two districts is seldom 
identical, owing to the great difference in climatic conditions, and I was 
therefore not surprised on examining the series in the collection of the 
Transvaal Museum to find that the sexed from Knysna were smaller 
than those from Grahamstown and elsewhere east of the Sunday River ; 
but it is only fair to state that the only other specimens are one sexed as 
a $ and another not sexed, so that it is possible the two sexed as $<$ may
