Hessamara, North Lakhimpur. A fine series of this Grass-Warbler was 

 collected hereabouts, it bears a striking superficial resemblance to Prinia 

 lepida, although of large dimensions, most diflicult to obtain amongst the 

 dense grass and reeds which it frequents. As this means a short range shot,, 

 the usual difficulty arises how to obtain specimens without mutilating the 

 skin and thus rendering it useless for preparation. December, January, 

 April. 



Iris sienna brown ; bill horny back or upper mandible dark 

 bluish horny ; lower mandible pale bluish horny. Tarsus horny brownish, 

 plumbeous or brownish slaty horny. These records extend its distribu- 

 tion considerably east. The types were secured at Dhubri, Lower Assam. 



95. Grayninicola bengalensis, Jerd. [388]. — The Large Grass-Warbler. 

 Obtained in the grass lands around Dinjan (Dibrugarh), 22-3-03, $, and 



seen at other localities on the Bramapootra and Subansiri ^' churs." A great 

 skulker and seldom shows itself. The crest feathers are distinctly 

 spinous. 



96. Megalurus palustris, Horsf. [389]. — The Striated Marsh- Warbler 

 "Tik tiki," Bengali. 



Resident throughout the plains. The vagaries of this Marsh-warbler, as 

 it rises and descends from and on to clumps of grass or reed jungle utter- 

 ing a lively trill attract the attention of the most casual observer. 



97. Phragamaticola aedon (Pall.) [393]. — The Thick-billed Warbler. 



Arundinax aedon, Gates, F. B. I., Vol. i., p. 393. 



Possibly only locally distributed, four, all males curiously, obtained at 

 Dejoo, North Lakhmipur, in more or less cultivated quarters. 17/20-4-07. 

 Silonii)ari, 29-8-11* seen about 6-30 to 7-0 a.m. in the bungalow compound 

 in the thick hedges and rose bushes, very windy last night, some rain. 

 This record is apparently on its first descent of a cold weaLher migrant. 

 Its song is very feeble. 



Iris pale brown; bill, upper mandible, dusky horny, lower mandible fleshy; 

 tarsus slaty plumbeous. 



98. Phylloscopus ajfinis (Tick). [405].— Tickell's Willow- Warbler. 

 Generally distributed throughout the plains in the cold season at all 



events, partial to light open tree and scrub growth, never found in forest. 

 Margherita, Rungagora, Hessanrara, Derpai, Dejoo. Colouration of soft 

 parts : Iris brown ; bill, upper mandible pale horny brown, lower mandi- 

 ble pale horny yellow ; tarsus olivaceous horny ; soles dingy-yellow. This 

 last character is well marked. 



99. Phylloscopus fuliginiventer (Hodgs ) [409]. — The Smoky Willow- Warbler. 

 Throughout the plains in the cold season, locally distributed owing to 



its habits as it is decidedly aquatic. Various weeds sedges and dead brush- 

 wood alorg the river banks afford it shelter and suit its requirements; 

 keeps much to the ground and hops in and about these haunts in pairs. 

 Plentiftil in March, April. Rungagora (R. Dibru). This Warbler bears a 

 close resemblance to P.fuscata homeyeri, and haunts similar localities. 



100. Phylloscopus fuscatafuscata (Blyth) [410] — Dusky- Willow- Warbler, 

 Plentifully distributed during the cold season as late as the second 



week in May. Dejoo, North Lakhmipur, 7-9-08*, 11-9-10*, 28-9-10 $, 

 12-5-07, S- Numerous records intervening dates for various widely sepa- 

 rated localities. Frequents low scrub and bushes. Often takes its food 

 on ground. It flits rapidly from cover to cover when on the move.
