The additional material I collected since submitting my i^reliminary 

 report gives little need for iurther comment. All the additional speci- 

 mens were taken during early summer. The female (ISTo. 92559) is the 

 I)alest one, with a decided cinereous tinge on the nape, corresponding 

 closely with the male described by Mr. Taczanowski {I.e.). 



With the same author I ngree in his opposition to including this spe- 

 cies in the genus Locustella.
