Coloration as a Factor in Generic Classification. 



The above note on a species of that large group of 

 Ringed Plovers, usually recognised under the generic title 

 ^gialitis'^, suggests another, viz., the importance of colour 



* I am personally of the opinion that by the rules of nomenclatui'e the 

 proper generic term for this group of Plovers should be Charadrius, while 

 the Golden Plover should be I'luvialis.
