in captivity in lower bengal. 245 



Observations on its habits. 



Once reconciled to captivity, it shows neither timidity nor shyness, 

 and keeps to the open parts of the aviary ; except for a moment or two, 

 when it descends to carry away its food it is never on the ground; 

 while sitting on a high perch, it occasionally takes short flights in the 

 air and again perches on the same spot ; this is probably instinctive ; 

 one may sometimes be seen sunning itself after a bath spreading its 

 wings; it has a harsh grating call, but is not a noisy bird. 



(139) THE BUEMESE EOLLEE. 

 (COKACIAS AFFINIS— McClell) 



Hab. — Except in the extreme south of Tenasserim, it is found 

 throughout Burmah; it is also found in Siam and Cochin-China, and 

 extends through the Indo-Burmese countries to Assam and as far west 

 as Calcutta. 



A specimen lived for about a month only. 



(140) THE RHINOCEEOS HOENBILL. 

 (BUCEEOS RHINOCEROS— Zmrc.) 



Description. — Head, neck, back, wings, breast, uniform bluish- 

 black; thighs, lower part of the abdomen, upper and under tail- coverts, 

 rump, pure white; tail pure white with black band across its lower 

 third (the width of the black band varies much in different specimens); 

 the most conspicuous point of this species is its large upturned casque, 

 which is generally red, but slightly yellowish anteriorly ; the bill is of 

 a light-yellow colour, having a triangular space of red at the base of 

 the maxilla, and of black on the mandible ; iris yellowish ; eyelid red ; 

 total length about 36 inches. Sexes slightly differ ; the back part of 

 the casque in the female is reddish instead of black, and the eyelids 

 are white. 



Hab. — Malayan peninsula, Sumatra, Borneo. 



Length of life in captivity. 

 About four years. 



(141) THE JAVAN EHINOCEEOS HOENBILL. 

 (BUCEEOS SILVESTKIS— Vieill.) 



Description. — In general appearance it resembles the preceding 

 species, but differs from it in having a casque which is straight and not 

 upturned ; the base of both the maxilla and the mandible black, edged 

 with red; the colour of the bill pale yellow, but it varies somewhat in 

 different specimens. 



Hab. — Java.
