bushy places. Besides at Amoy, I have also observed it at 

 Hongkong and Fowehow. 

 27. Prinia sonitans, n. sp. [Ibis, Vol. II, 50.] 



I have named this from the crackling noise it produces when 

 hopping or flying from twig to twig. 



Length 5-^ • wing 1 T 7 7 ; tail 3. Bill along culmen ^ to gape 

 ^. Tarsus -^ ; middle toe ±% ■ outer sightly longer than 

 the inner, hind-toe ^-. Bill and inside of mouth black. Irides 

 orange-yellow. Legs buff, browner on the claws. Head fine 

 deep bluish-grey ; chin and cheeks white ; occiput and back 

 olive-green, blending with the grey towards the fore-part and 

 becoming tinged with sienna on the rump. Wings light hair- 

 brown margined with buff olive-green. Tail pale brown, mar- 

 gined and tinged with buff olive-green. Breast a clear pale 

 buff tinged with primrose, deepening on the under-parts and 

 very deep on the thighs. 



The female has the head less bluish than the male ; and in the 

 young the head is uniform with the back. 



This species is resident here, and builds domed nests on the stalks 

 of reed-plants ; the eggs, 7 or so in number, are strangely red. 

 Mr. Blyth remarks on our bird — " Your Prinia from Amoy 

 comes exceedingly close to P.flaviventris, Delessert, which is 

 common in the Bengal Sundarbans, Tenasserim, &c, and I 

 have received it also from Singapore ; but yours has a longer 

 tail, wants the bright yellow of the lower-parts below the 

 breast, and there is an admixture of white in the loral region and 

 ear-coverts not seen in our species. Moreover, Pr. flaviventris 

 lays a similar red egg, as I am informed by Major S. R. 

 Tickell." 

 28. Drymoica extensicauda, n. sp. \_lbis, Vol. II, 50.] 



A common resident, and seems to delight in fields of grain, long 

 grass, &c. It is often seen standing on a stalk, throwing up 

 its tail and twittering a short series of unmusical notes. 

 Length 5^ ; wing 1 t 9 q ; tail 2f, long and graduated deeply, the 

 outer feather measuring only 1 T 3 7 . Bill along culmen ^L, to 

 gape -j- 6 ^ ; deep blackish-brown, paler just at the tip, and yel-
