Serilophus lunatus stolidus, subsp. nov. 
Serilophus rothschildi Robinson, Journ. Fed. Malay States 
Mus. v. 1915, p. 97 (Kao Nawng, Bandon). 
We have long considered five specimens from the above 
locality in our collection not strictly referable to any known 
race; the acquisition of a large series of more typical 
S. lunatus now enables us to name them. 
Separated from S. 1. lunatus by the deeper-coloured inner 
secondaries and tertiaries, the innermost of which do not 
show dusky bases, and also by the slightly more drab, less. 
fulvous ear-coverts; from S. 1. rothschildi of Perak and 
Selangor by the fulvous crown and ear-coverts and paler 
chestnut rump and secondaries ; and from S. l. intensus by 
the lighter grey underparts and paler upper parts. 
Types. & ¢ adult from Kao Nawng, Bandon, Peninsular 
Siam, 1200-1500 ft., collected on 19 and 23 May, 1913, by 
H. C. Robinson and H. Seimund. 
Specimens examined. The typesand two immature birds 
from the same locality compared with 5 g and 6 2? of Seri- 
lophus lunatus lunatus from the Pakehan Hstuary and 
Chumporn; 3 g and 5 ¢ of S. l. rothschildi from the 
Federated Malay States; 6 ¢ and 9? of S. Ll. intensus from 
Korinchi, W. Sumatra; a pair from 8. Sumatra (Bencoolen 
and Palembang Residencies) and one from Deli, N.H. 
Sumatra. 
In this connection we may note that Hume states (Stray 
Feath. iii. 1875, p. 53) that the thighs are deep chocolate- 
brown with sometimes a white spot inside, immediately above 
the articulation: in all the specimens we have examined the 
thighs are dead, not even sooty, black. If Hume is correct 
. the South Tenasserim and South-western Siam bird is again 
different from that of Pegu; it is unlikely that the type 
actually came from Rangoon. 
Rhinocichla mitrata major, subsp. noy. 
Distinctly larger than the typical Sumatran race: wing, 
minimum (of twenty-six specimens) 100, maximum 119,
