Gmelin’s name mulabaricus does not apply to this bird at all. 
His bird is named after the Calao de Malabar, Buffon, Hist. Nat. des 
Ois., and here a good plate is given which shews that malabaricus 
is the same as coronatus, the outer tail feathers proving this beyond 
all doubt. 
Shaw and Nodder give both description and plate of albiros- 
tris from India, and it is probable that the proper name for the 
Burmese form is lewcogaster of Blyth (J. A. S. B. x, p. 922, 1841) 
described from a bird seat by a Mr. Bark from Tenasserim with 
some other skins of birds and mammals.

All races of the Eastern Hoopoe, 7. ¢., of races east of Sikkim, 
are distinguished by being much larger than those to the west, and 
with having an even proportionately longer bill on an average, though 
abnormal birds are found everywhere with very long bills. Thus in 
Ceylon the average is only 47.5 mm. in a small series, but there is 
one bird with a bill of 57 mm. In Southern India a large series 
averages 48 mm. exactly, but there is one specimen which has a bill 
of 73 mm. ; 
Assam birds are huge, and have wings averaging 146.1 mm. 
and bills of 54 mm., Burmese birds have these measurements res- 
pectively, 139.5 mm. and 54.5 mm., whilst Siam birds have wings of 
142.5 mim. and bills just over 51 mim. 
Under the circumstances I retain them, under the name 
longirostris, the Assam birds forming a link with the still larger 
Tibetan form sutwrata.
