Ad. supra nigricans, sordide cyanescente nitens : subtus albus, pectore laterali dorso concolori : ala quoque 

 dorso concolori, secundariis anguste albido terminatis : supercilio distincto a naribus ducto et pileum 

 marginante, postice cristato, dilute sulfiireo : facie laterali gulaque nigricantibus vix brunnescenti-albo 

 variis : rostro rubescenti-brunneo ad basin nigricante : pedibus flavicanti-albidis, subtus nigricanti- 

 brunneis : iride flavicanti-brunnea. 



Adult. Crown, sides of the head, tbroat, and bind part of neck black ; the rest of the upper surface bluish 

 black, each feather having a narrow central streak of pale blue ; from the base of the upper mandible, 

 on each side, a broad line of pale golden-yellow passes over the eyes, and is continued beyond in a crest 

 of fine pointed feathers, extending nearly two inches beyond the head ; the black feathers of the crown 

 between these side crests are lengthened, acuminate, and slightly rigid ; upper surface of flippers glossy 

 bluish black, the feathers, which are lanceolate and closely imbricated, being margined and tipped with 

 pale blue; along the inner edges a narrow band of white. The underparts of the body are silvery 

 white, contrasting sharply on the sides with the dark plumage of the upper surface, and tapering upwards 

 on the fore neck to a point about three inches below the angle of the lower jaw; under surface of 

 flippers bluish grey, with the central portion outwardly, and a continuation towards the root, silvery 

 white ; tail-feathers long, narrow, very rigid, and perfectly black ; the coverts greyish white, with black 

 shafts, and tipped with blue. Irides yellowish brown ; bill rich nut-brown, darker on the lower man- 

 dible, blackish at the base, and horn-coloured at the tip ; feet yellowish white, with darker webs ; claws 

 dark brown, with black points, the soles blackish brown. Total length 27 inches ; length of flipper 8'5 ; 

 tail 4; bill, along the ridge 2'75, along the edge of lower mandible 2*75 ; tarsus 1*5 ; middle toe and 

 claw 35 ; hind toe and claw "75. 



Young. Differs from the adult in the character of the crests : instead of the broad superciliary band of 

 golden yellow, there is a narrow line of pale yellow, beyond which there are a number of narrow 

 straggling feathers, forming, so to speak, occipito-lateral crests. Moreover, in the specimens that I 

 have examined, the black appears to extend further down the throat, the white on the fore neck forming 

 a less acuminate termination.
