Genus CISTICOLA Kaup 



The treatment given the forms of this difficult genus in this report 

 follows the conclusions arrived at by Lynes in his superb mono- 

 graph,^^ This work has rendered a perusal of earlier literature quite 

 unnecessary, and so no discussions of names, synonyms, etc., are 

 included here. The most critical test of a monograph such as Lynes's 

 is applying it to a large museum collection, and I am happy to add 

 a quite unnecessary word of praise to the many alread}^ accorded it. 

 Lynes's book has not fallen down in a single case ( I have reidentified 

 all the Cisticolas in the United States National Museum with it at 

 hand) and it has brought order out of chaos in a manner that is far 

 easier to admire than to imitate.
