S. Mengtsz, , was immediately noticeable due to its weakly developed head stri- pe and the absence of a "wing shadow"'. Ticehurst (1938:119) declared. 'The presence or absence of the dusky spot on the wing below the lower bar is purely an indi\idual varia- tion". He studied 170 skins of chloronotiis. Eck examined 113 skins of the forms prore- gulus, chloronotus (inch forresti, newtoni) and simlaensis, and found only two from Nepal that clearly lacked this "shadow" below the wing bar! Both birds must for the time being be regarded as belonging to simlaensis: S, Gompa, V, well developed testes; S, Dhorpa- tan, V, well developed testes (see Material). However, they differ in their wing/tip indices (WTI), that of the former being and of the latter, ! The latter WTI is well be- low all the other WTI's. Furthermore, the S from Gompa (higher WTI) has a wing length of a good 56mm, while the one from Dhorpatan, with WTI of only , has wings on- ly mm long (). Ticehurst noted for S of chloronotus and simlaensis a. mini- mum of mm (evidently with no specimen from Nepal), whereas Biswas (1962b: 416) reports 48-58 mm for 6 S from central Nepal ( ssp. chloronotus). It seems clear that a 10-mm range of variation for these small warblers is out of the question. La Touche (1922) reported 52-54 mm for 5 yunnanensis. 8 chloronotus S from Nepal have wing lengths of 50-57 mm, while those of 7 simlaensis 6 from Nepal are 53-56 mm and of 3 additional simlaensis (?) 6, 48, and mm (giving an overall range of 48-56 mm); the last 3 6 had WTFs of , and (!) and were col
