many of them nesting among the reeds and willows near 

 Hatzeg, but since that time he has seen none. Herr Csato 

 mentions that, in May and June of the same year, Herr Buda 

 and himself shot some specimens in the Kriseny marsh, and 

 further says : — " It is not shy, and sits on the top leaves 

 of reeds, uttering its grating note [schwirrenden Ton] from 

 early morn till night/^ He has happened to hear A. lusci- 

 nioides, A. locustella {rayi, Penn.), and A. fluviatilis all to- 

 gether, and makes the following distinctions : — 



A. luscinioides. Buzzing note weaker, one-toned, and 

 shorter than fluviatilis. Sits on the upper leaves and dry 

 tops, and is only found in marshes. 



A. fluviatilis. Buzzing note double-toned, loudest, and 

 longest. Sits on branches of alders, near the trunk, and on 

 bushes and ferns. 



A. locustella. Buzzing note weakest. Sits on the top 

 twigs of willows.

Not uncommon among the reedy lakes of the Mezoseg and 

 other localities, but, from their mouse-like habit of running 

 and creeping at the bottom of the reed-stems, are rather ditii- 

 cult to obtain. We found them at Tohat and Zah. 



121. AcROCEPHALUS PALUSTRIS (Bcchst.). 



Common in marshy and willowy ground. Herr Csato says 

 it nests in the hemp- and rye-fields in the Strell valley. 



*122. AcROCEPHALUs sTREPERus (VieiU.). 

 Common in marshes and by river-banks. 



■^123. AcROCEPHALUs ARUNDiNACEus (L.) . NcUU Vcreb 

 (Reed-Sparrow). 



Very common in the Mezoseg, their harsh grating cry re- 

 sounding from among the reed-beds in every direction. 



"^124. MoTAciLLA ALBA, L. White Wagtail. 

 Common everywhere.
