While it is true that there is a tendency among more southern examples of this 

 species to a more brownish tone of coloration, the difference is far from being suffi- 

 ciently constant to warrant their subspecific separation. The extremes of graynesa 

 and brownness are shown in specimens from Guayabo, Costa Eica, while the series 

 from Nicaragua and Panama, respectively, show both styles of coloration.
