nor C are met with. There will always be found some people 

 who disapprove of calling these intermediate forms by distinct 

 names, but after all it is only a matter of convenience, and 

 perhaps the most satisfactory plan is that which we have fol- 

 lowed — viz., treating them as sub-species of the type to which 

 they show most affinity. 



Another way of getting out of the dilemma is by the use of 

 trinomial nomenclature. To those who follow this objection- 

 able plan, G. cuvieri would be known as G. horsfieldi lineatus^ 

 and G. oatesi as G. liiieatus horsfieldi. 



Lastly, I must remind my readers that the female of G. 

 oatesi (BA) is somewhat different in plumage from both B and 

 A, and may be easily distinguished from all the females of the 

 various species of Gennceus. 



I have at present only been able to examine a very limited 

 number of skins of these intermediate forms, as few Europeans 

 have visited the countries wliere they occur, but it is greatly 

 to be hoped that those who have opportunities of visiting 

 the Arakan Hills or Upper Salween Valley at some future 

 time, will endeavour to shoot and preserve all the Kalij 

 they come across. A good series of these intermediate 

 forms would be an extremely valuable and welcome addition 

 to the National Collection.
