110 BIRDS OF TENASSERIM. 



anterior angle of the eye ; angle of the gonys and base of 

 throat, and eyelids mottled black and white. 



Dr. Cautor, no doubt, describes the same parts of the Malaccan 

 bird as being black. Possibly he described from a female and 

 the colors not improbably differ in the sexes, or he may have 

 described from a dried skin, in which the parts do become black ; 

 and as alike in Tenasserim and the Malay Peninsula these 

 birds are extremely shy and difficult to shoot, Dr. Cantor is 

 not likely to have shot one himself, and in that climate the 

 colors of the soft parts change very rapidly after death. 



The feathers of the occiput and sides of the head elongated 

 so as to form an excessively full crest, extending backwards 

 5*25 inches from the posterior margiu of the casque ; the fore- 

 head, entire top, back, and sides of the head and neck, crest, 

 and entire upper parts, dark brown, with a strong metallic green 

 reflection ; ear-coverts rather darker and wanting this reflection ; 

 feathered portion of throat, breast, abdomen, a dull chocolate 

 brown, somewhat paler in the middle of the abdomen ; the 

 feathers somewhat glossy, but almost entirely wanting the mark- 

 ed green reflections of the upper surface ; tibial plumes simi- 

 lar but darker, and exhibiting more of these reflections ; vent 

 paler and drabby ; lower tail-coverts a somewhat pale drab 

 brown, fringed paler. 



Wing, as usual, much rounded ; fifth, sixth, and seventh quills 

 equal and longest; tail somewhat rounded ; external feathers 

 1*5 shorter than central ones. 



Tail with about the basal three-fifths greyish drab ; terminal 

 two- fifths black or nearly so, glossed with green, as the rest of 

 the upper parts. 



The/quills have a barely perceptible pale brownish margin 

 to the outer webs. 



Temminck's figure, PI. Col., 520, which is extravagantly ill- 

 colored, clearly represents a not perfectly adult bird ; the white 

 patches on the beak and the conspicuous pale margins to the 

 quills being, as we know, from young specimens obtained in the 

 Straits, signs of immaturity ; in the young bird, besides these 

 points of difference, the crest is much less developed, the colors 

 are everywhere duller, the basal portion of the tail is browner 

 and less of a greyish drab, and the entire lower breast and 

 abdomen is much paler and more of an earthy brown. In the 

 adult in good plumage the lower surface of the basal portion 

 of the tail is pure grey. 



146. — Aceros nipalensis, Hodgs. 



Colonel Tickell recorded this from the Tenasserim Hills, and 

 Davison saw it repeatedly at Mooleyit, and near enough to
