Di'. Bayori's collection tliere are all the interg'rades, in wliicli these 

 markings are more or less reduced , to connect them , and in 

 Adamua, German Cameroons, from whence several of the inter- 

 mediate forms liave been described by Kraatz as se})arate species, 

 a similar variation occurs, liut it is curious tliat in an enormous 

 series of both trivittala and afzeli from Sierra Leone, tliat I had 

 an opportunity of examining, botli forms were uniformly constant. 

 Besides these intermediate forms many other variations in size 

 and coloration have been named by recent autliors as species, 

 sub-species, local i-aces and varieties, but as tlie connecting links 

 Ijecome known it is found impossible to difierentiate them, and 

 the distinctive names therefore become useless, and I believe the 

 synonymy of this variable species will be as follows : 



With white or pair markings. Hitliout wliite or pale marliings. 

 Legs black. Legs black,
