SAVI'S WAKBLER. 



This species seems to be generically inseparable from the 

 Sylvia fluviatilis of Johann Wolf, made by Dr. Kaup, in 1829, 

 the type of his genus Potamodus. In 1838 Bonaparte pro- 

 posed for Savi's Warbler the generic name of Pseudoluscinia, 

 which a few years later he altered to Lusciniopsis, and one 

 or the other of these terms has since been very commonly 

 used for it. But, if the group of aquatic Warblers be further 

 broken up, the name Potamodus should certainly be used for 

 that section which contains Savi's Warbler and the River- 

 Warbler just mentioned two species which agree in every 

 essential character, and in appearance differ chiefly by the latter 

 having a much less rufous tinge generally, and its throat 

 being distinctly striped with dark longitudinal markings. 



The vignette represents the nest of Savi's Warbler given 

 to the British Museum by Mr. Bond as before mentioned, 

 and the first ever brought to the notice of naturalists, 

 for the opportunity of figuring which the Editor is indebted 

 to the kindness of the authorities of the Museum, and 

 especially to that of his friend Dr. Albert Giinther.
