1877.] MR. D. G. ELLIOT ON THE IBIDIN^. 491 



believe judging from the examples I have seen, that the Siamese birds, 

 when ahye,have veryhttle white on the neck, the indication mentioned 

 above being possibly caused by the rose-colour having entirely faded 

 out. There was, unfortunately, no description of the colours of the 

 naked skin sent with the specimens. The neck and upper part of the 

 rWlJ Jfl ™^""l^'-«^»' 8l«i««d with greenish bronze. Upper tail-coverts 



like the back, some of the feathers having the webs disunited and 

 ont^:*. I'nmanes and wings very deep rich Prussian blue, the lesser 

 coverts white. Tail Prussian blue, with a green gloss on the edge of 

 he feathers. Underparts rufous-brown, glossed with green. Under 

 tail-coverts green with a blue tinge. Bill, accordhig to Hume, 

 very dark plumbeous, blue at base, shading to a dull ochraceous 

 clay colour towards the tips." In the specimens before me it is ap- 

 parently dark green, lightest at the tip. Legs and feet coral red. 

 Hume gives the irides as "bright orange." Total lei.eth 33 

 inches; wmglGi, tail 8 bill al<^ig culmen 6^, tarLs 3 Inches 

 Another specimen, also brought by M. Harmond from Camboja, 

 measures as follows :-total length 37 inches; wing 161. tail ^ 

 bil along culmen /|, tarsus 3| inches. It appears to be a larger 

 and stouter species than the I. papiUosus. The sexes unfortunately 

 are not indicated in any ot the specimens. There are such trenchant 

 differences exhibited b^ this species from all others of this group of 

 birds, especially m the shape of its skull, which resembles somewhat 

 ot that its gigantic relative the Thaumatibis gigantea, that it would

Graptocephalus, 



with the following characters : — 



Head and neck bare, covered by a variously coloured skin. Skull 

 square-shaped on top ; occipital region high and wide, sloping to 

 the forehead, which is prominent and descends rapidly to the maxilla 

 Secondaries are equal in length to the primaries, and both reach 

 near y to the tips of the rectrices. Second and third primaries equal 

 and longest. Tarsus half an inch longer than the middle toe ; outer 

 toe slightly longer than inner. Tarsi covered with small hexagonal 

 scales. Under tail-coverts extending over two thirds the length of 

 the tail, ° 



I could not remove the skull, and therefore am only able to 

 describe the form as it appears in the skin.
