26 Mr. C. H. B. Grant on a Collection of 



The one adult female I have examined, a head from 

 Kaniassia, shows that the helmet is smaller than in the 

 males, but is strongly and well formed, as opposed to the 

 weakly formed helmet of its allies. 



Even the young bird has the helmet far more developed 

 than in young birds of its allies, in fact tlie helmet is equal 

 in size to that of many adults of the other races. 



The head from the Turkwel River undoubtedly belongs 

 to this race, so that it is probable that it ranges somewhat 

 into the country of N. p. major. 



In naming this race I have had occasion to examine the 

 whole of this group of Guinea-Fowls, and I have to thank 

 Mr. llothschild and Dr. Ilartert for the loan of thirty 

 specimens from Tring, which, combincil with material in 

 the National Museum, have given me a hundred specimens 

 of this group for examination, and these from localities 

 which cover the whole of its known range. 



The races I am able to recognise are as follows : —
