noticeable that the smallest bird in the whole series of 

 skins of this species is a fully adult male in perfect 

 plumage from Kaukaryit with a wing of only 109 ram. 

 The following subspecies seem to be maintainable : — 



(1) Thereiceryx lineatus lineatus. 



Cupito iineatus Vieill. Nouv. Diet. d'Hist. Nat. iv. 1816, 

 p. 500 : Java. 



Very small; \vi»ig average 117"3 mm. (13 birds). 

 Habitat. Java and Bali. 



(2) Thereiceryx lineatus hodgsoni. 



Megalcema hodgsoni Bonap. Consp. Av, i. 1850, p. 144: 

 Nepal. 



Meyalcema maclellaruli Moore & Horsf. Cat. ii. p. 637. 



The tyi)e of M. maclellaniU is said to have come from 

 north-east Bengal, and the ticket on the type itself is 

 marked as from Assam ; as Assam at one time formed the 

 north-east corner of Bengal both are correct, but the name 

 is merely a synonym for T. I. hodgsoni. 



A very large bird : wing about 130G mm. (103 birds). 



Habitat. Nepal, through the Himalaya and eastern Bur- 

 mese Hills to Siam north of the Peninsula. 



(3) Thereiceryx lineatus intermedins. 



Stuart-Baker, Bull. B. O. C. xxxix. 1918, p. 9: Pahpoon, 

 Burma. 

 Type. No. 88.11.30.449, ? , ex Hume Coll., Brit. Mus. 

 Intermediate in size between T. 1. hodgsoni ajid T. I. 

 lineatus, with a wing of about 124 mm. (71 birds). 



Habitat. Central and south Burma and penin.sular Burma 

 and Siam. 



? (4) Thereiceryx, ?subsp. nov. 



From N.W. India. 



A very large bird, with an average length of wing over 

 137 mm. 



If a sufficient series of specimens from the north-west of 

 India west of Nepal shows that the great size is consistent, 

 this will suffice to constitute a fourth geographical race.
