316 MESSRS. ROBINSON AND KLOSS ON 



Total lengtli 135 ; wing 67 : tail 52 : tarsus 23 ; bill from 

 gaj)e 17 mill. 



We have examined twenty-six si^ecimens collected by Mr. 

 W. J. F. Williamson in Bangkok, all obtained between September 

 and March : the wing lengths range between 64 and 70 mm. 



We have examples of the Eastern Bush-Chat from Kuala 

 LumjDur taken during the winter months. 



It is possible that the birds referred to by Hume and Davison 

 and by Gates in our synonymy belong in part to the following form. 

 449. Saxicola torquata przwalskii (Pleske). 



Prutlacola maura var. Przwalskii, Pleske, Wiss, Res. Przw. Reisea, 



vog. I, 1889, p. 46, taf. iv figs. 1, 2, 3 (Kansu). 

 rratincola torquata przioalskU, M., p. 409 (Maprit). 



Herbert's S bird from Maprit had a wing, according to Baker, 

 of over 72 mm., and was provisionally recorded under the above name. 



The Malay Peninsula and Bangkolv_are obviously the wiuter- 

 in<^'- area of the smaller eastern race, but it is quite possible that a 

 few individuals of the larger form visit it also. 

 Calliope calliope (Pall.).

(Siberia). 

 Calliope caint^fchatkeiisis, Williamson, Journ. N. H. Soc. Siam, ii, 



1917, !>. 187 (Bangkok). 

 This bird will probably be met with in the extreme north of 

 our ret'"ion : it is not uncommon at Bangkok in the winter. 

 Cyanosylvia suecica subsp. 



MotaciUa suecica, Liun., )Syst. Nat. i, 1766, p. 336 (partim: Sweden). 

 Cjjanecula suecica, A., p. 337 (Tavoy) ; Williamson, Jom-n. N. H. 

 Soc. Siim, iii, 1918, p. 21 (Bangkok). 



Numerous examples of this species were taken at Bangkok 



during the winter season of 1917-18 by Mr. W. J. F. Williamson at a 



time of exceptional tioods in that part of the country, but it is not 



certain that the bird occurs there regularly : it may possibly be met 



Avith eventually just within our area.
