The species, curiously enough, does not seem to have 
been hitherto recorded from Sumatra itself, though we have 
obtained it from the Aroa Ids. off the east coast (Journ. Fed. 
Malay States Mus. ii, p. 15 (1906). In the Malay Peninsula it 
is exceedingly common from September to May, though 
possibly it does not reside throughout the year. 
In habits the bird is a ground chat, having the manners 
of Brachypteryx and Notodela, though it is not so strictly 
terrestrial as either of these genera. It cannot, we think, be 
correctly placed with the Robins, as has been done by 
Seebohm, insomuch as the nestlings and quite young birds 
have not a spotted plumage. 
142. Notodela diana subsp. sumatrana nov. 
a-t. 66,3¢%. Sungei Kumbang, Korinchi, Sumatra, 
4,600 feet. 31st March-16th April. [Nos. 
531, 559, 598, 721-2, 828-9, 903, 947.] 
“Tris hazel, bill black, feet dark purplish slate.” 
Males :—Duller than Notodela diana diana of Java and with 
the white neck spots and frontal area larger. The general 
colour of diana may be described as dark “indigo blue;”’ that 
of sumatrana as “dark Payne’s grey’ (Ridgway). 
Females :— Brown of upper parts perhaps a little deeper 
than in Javanese birds, the throat darker and the fore-neck 
without the ill-defined pale greyish patch. 
Types :—Adult male from Sungei Kumbang, Korinchi, 
4,700 feet. Collected on 2nd April, 1914, by H.C. Robinson & 
C. Boden Kloss. [No. 559.] 
Total length, 152; wing, 79; tail, 67; bill from gape, 17; 
tarsus 28.5 mm. 
Adult female :—Same locality, etc., collected on rath April 
IQI4. 
Total length, 140; wing, 77; tail, 60; bill from gape, 18.5; 
tarsus, 25 mm. 
The habits of this species are exactly those of the species 
of Brachypteryx. It is found in pairs among thick undergrowth, 
or fallen timber, and never comes into the open. We only 
found it in the zone between 4-5,000 feet, where it was fairly 
common but not nearly so abundant as By. leucophrys. 
The genus is new to Sumatra but the Himalayan form, 
N. leucura (Hodgs.) is met with on the mountains of Central 
Perak, Malay Peninsula. -
