EHTTIDOCEEOS. 81 



except in size. They average much smaller, but a large egg of the 

 present species is quite as large as a small one of D. hicornis. 

 They are precisely the same shape, size, and vary in the same way 

 in regard to gloss and colour, though 1 have seen none so dark as 

 some of those of A. tickelli, but the shell is finer, and in no speci- 

 men have I noticed the uniformly pimpled appearance so common 

 in the eggs of B. hicornis. 



Eleven eggs measure from 2-3 to 2-65 in length by 1*62 to 1'87 

 in breadth. 



Ehytidoceros subrnflcollis (Blyth). Blyth's Wreathed Homhill. 



Khyticeros auhruficollis (Blyth), Hume, Rough Draft N. ^ E. no. 146 

 bis {Cat. no. 146 ter). 



Mr. W. Theobald makes the following remarks on the breeding of 

 this species, Blyth's Wreathed Hornbill, in Tenasserim ; — " Lays in 

 the third week of February. Eggs, three in number ; ovato-pyri- 

 forin. Size 2'20 inches by 1*55 inches. Colour, pure white. 

 Mode of incubation said to be similar to that of the Homrai." 



Major Bingham, writing from Tenasserim, remarks : — " I have 

 as yet taken no eggs of this species, though I found several nests, 

 which were precisely Uke those of B. undulatus, but in immense 

 high trees, and far more secure than the nests of any other species 

 from the height and inaccessibility of the localities chosen. The 

 entrance holes were closed up exactly in the same way as in the 

 case of the others, with a plastering of mud, &c." 



He subsequently wrote: — "It is not very abundant in the 

 Thoungyeen, and I only got two nests, one on the 5th March with 

 two eggs, and the other on the 7th, with only one egg. The three 

 eggs measure respectively 2-22 x 1-63, 2-28 x 1-68, 'and 2-49 X 1-78. 



"In the next year I got one nest on the 1st March at Meea- 

 wuddy containing one egg, 2-3x1 '65. Nest in the hollow of 

 myoukchaw tree {Homalium tomeniosum) at a height fully of 60 

 feet from the ground." 



Mr. Gates found the nest in Pegu. He says : — " A man on the 

 22nd March found a nest of this species. It vias placed in a 

 wood-oil tree about 70 feet from the ground. It contained only 

 one egg, which was nearly hatched. In colour it is a duU white 

 without any gloss, and the shell is rather rough to the touch. It 

 measures 2-25 by 1'5. These dimensions agree well with Mr. 

 Theobald's." 



The eggs of this species appear to me to be absolutely undistin- 

 guishable from those of jR. undulaiug, and therefore no separate 

 description is necessary.
