d; Mongtse, S. Yunnan, 2. vi. 10 (Owston). 



The distribntion of this bird is given by Sharpe {Handlist, iv. p. 237) as 

 follows : E. Himalayas (Sikkim to Assam) ; Manipiir ; Bnrmese Provinces (Karen- 

 nee, Muleyit) ; Malay Peninsula. It is therefore interesting to find it in Ynnnan.

255. Prinia inornata extensicauda Swinhoe. 



Drymoipus inoniatns Anderson, Western Ynnnan, ii. p. 640. 



A series of nine specimens, ei^Hit males and one female, shot at Mon.stse, 

 Ynnnan, iu April, May, June, .Jalv lUlO (ISTos. 21, .30, 63, 101, 208, 255, 256, 257, 

 287). 



Compared with typical P. i. e-ctensiciuda from the Amoy, birds from Ynnnan 

 and Upper Burma have very small bills ; on the other hand, those from Formosa — 

 as Swinhoe pointed out in 1803 {Ibis, 1863, p. 299)— are "rather larger," and 

 possess "usually more robust bills." They all agree, however, in having the back 

 generally greyer and more olivaceous than P. inornata. In some examples of the 

 latter, noticeably from Mnddapur, the up])er parts are very brown, fre<juently with 

 a rnsty tinge on the lower back and mm]), and South Burmese birds (so-called 

 i/rtK/b/Y/i) are often very fulvons about the head and nnderparts. Of course these 

 warm tints may be largely' due to season, and are certainly more apparent in winter- 

 killed specimens. 



This group is umiuestionably a difficult one, and we will need to compare a 

 very large series of skins with full data (which is often not forthcoming in some 

 of the older specimens), before we can come to any definite conclusions. 



Having examined the specimens in the Triug and British Mnseums, we publish 

 the following notes iu the hope that they may lie useful to future workers : — 



Prinia inornata inornata Sykes. 



Upper parts brownish, with freijuently a distinct rnsty tinge on lower back and 

 rump. (The rufous tints are more pronounced in winter.) Average length of wing, 

 oO ram. 



Hah. Indian Peninsula. 



Prinia inornata jerdoni (Blyth). 



Slightly larger. Upper parts usually darker and less rufous, even iu winter. 

 Tail shorter, with subterminal spot more distinct. Average length of wing, 52 mm. 

 Ilnb. Extreme south of Indian Peninsula and Ceylon.
