Calyptomena viridis continentis subsp. nov. 
Like C. v. viridis Raffles, of Sumatra (type locality 
restricted to Benkoolen District) but ranging larger : wing 
attaining a length of 113 mm. 
Our Sumatran birds, of which we have only four 
examples, have wings 93-97 ; Bornean birds, wings 94-103 
(25 ex.), and a larger Sumatran series would probably 
show nearly as high a maximum. Malay States birds have 
wings 97-107 (27 ex.) ; Peninsular Siam, 99-112 (13 ex.) 
and Tenasserim birds, wings 105-113 mm. (fide Hume, 
Stray Feathers, VI, 1878, pp. 86, 499: Amherst to 
Malewoon). 
The island birds combined have extremes of 93-103, 
the continental 97-113 mm. 
The Malay States birds are intermediate but since they 
range larger than any of the Sumatra-Borneo series it 
seems for the present advisable to place them all with the 
northern form.

Nitidula hodgsoni sondaica subsp. nov. 
Differs from the typical form from Nepal in more 
coerulean, less indigo, upper side: head not appreciably 
brighter than mantle and back : ear coverts washed with 
blue, not uniform black. Size similar. 
Type. Adult male from Korinchi Peak, W. Sumatra,

Specimens examined from Sumatra (Korinchi Peak), 
mer Peninsula (Semangko Pass), Borneo (Kinabalu and 
ulit). 
Pomatorhinus montanus occidentalis subsp. nov. 
Like P. m. borneensis but ranging larger and with a 
larger bill. Tail more washed with russet. 
Eleven Bornean birds from Sarawak have wings 78-87 
mm. ; bills, tip to nostril, 14-7-16-4 mm. 
_ Twenty Malayan birds (Perak to Negri Sembilan) have 
wings 81—96 mm. ; bills, tip to nostril, 16-0-18-5 mm. 
Four West Sumatran examples have wings 86-88 mm. 
and bills 17-9-18 mm. : these we place with the Malayan 
orm,
