In spite of assiduous collecting in the Malay States for 

 many years, we have not succeeded in obtaining any speci- 

 mens of Chrysocolaptes except on Lang Kawi Island and 

 again in the extreme south, where it reappears once more 

 after a gap of several hundred miles. 



An adult male from Singapore Island has a wing of 

 143 mm., and another from the coast of Johore opposite 

 measures in wing 146, while its bill is also considerably 

 shorter than those of northern examples — in fact, these 

 are altogether smaller birds, and on this account may be 

 distinguished as 



-^ Chrysocolaptes strictus chersonesus, subsp. nov. --^ 



I do not see how Picus strictus Horsfield, of Java, can be 

 maintained as specifically distinct, so being the oldest name 

 (Trans. Linn. Soc. xiii. 1822, p. 176) it must have pre- 

 ference over all others.

Gyldenstolpe writes: — "The Rufous Piculet inhabiting 

 Siam belongs to the form which Hesse has separated under 

 the name of S. 0. reichenoivi. This subspecies also inhabits 

 North Cachar, Burma, and Tenasserim. It is chiefly cha- 

 racterized by its being much brighter-coloured on the upper 

 and under-parts of the body. Its size is also much smaller 

 than typical S. ochracea Hodgs.^^ 



I have not seen Hesse^s paper, but my female, as com- 

 pared with a specimen from Sikkim, 6000 ft., and another 

 from the Garo Hills, Assam (both unsexed), is paler above 

 and below, more ochraceous, less rufous, and the head and 

 wings are perhaps rather more olive. The wing is the same
