Irides clear pale brown, paler at the inner and outer edges, and 

 surrounded for a fourth of an inch by an injected red sclerotic, which 

 becomes white posteriorly. Bill from 12 to 13 inches long, measured 

 along the central ridge of the upper mandible, which ridge is pale 

 flesh colour, with the lateral expansions deeper in colour and marked 

 with a series of leaden black or purplish subquadrate oblique macula? 

 in either a single or, towards the base, a double row. Nail arcuate, 

 dull yellow. Lower mandible greyish flesh colour, becoming orange 

 towards the tip. Grilar pouch, when lax, very pale slate colour, 

 anteriorly with orange caruncles towards the base ; when stretched, 

 of a lurid flesh colour with well marked veins. Legs and feet dull 

 slate colour, or bluish flesh colour. Claws whitish lead colour, paler 

 towards their tips. Total length from tip of lower mandible to tip of 

 tail, 4-i- feet. Wing 21 to 22£ inches, with the 3rd and 4th quills 

 longest, and the 2nd shorter than the 1st. Tarsus 3^ to 3^ inches. 

 Midtoe, including claw, 5 to 5£ inches. Inner toe, including claw, 

 5J: inches. Outer toe 5 inches. 



The species does not breed in any part of the Peninsula with which 

 I am acquainted. It perches though rarely upon very lofty trees, 

 and a similar habit has been noticed by G-riffith in the Pelican of the 

 Jheels of Eastern Bengal, but its usual roosting place is at sea. The 

 Malays term it " hurong Jawa" literally bird of Java. The marks 

 on the bill occurred in every specimen which has passed under my 

 observation. 



3. Limnaetus alboniger, (Horsf. ?)* 



[Spizaetus cristatellus, Jardine and Selby, in more advanced plumage 

 than the very young individual represented in the ornithological 

 illustration of those authors.]! 



This bird settles a point long in dispute, namely the identity of 



* Horsfield (Cat. of Birds, I. p. 33) quotes ? Nisaetus alboniger, Blyth, as 

 identical with. Spiz. caligatus, and Spiz. cristatellus, Temm., as a distinct variety 

 ' of the same, but I cannot find the reference to Lim. alboniger, Horsf.— Nat.

f Jardine and Selby's (Ornith. II. p. 66) Spizaetus cristatellus is describ- 

 ed from a specimen, said to have been shot by the Captain of a vessel about to 

 enter the port of Aberdeen. The forehead of the specimen is whitish, the rest 

 of the upper plumage brown, below and sides of neck white, tail greyish with 7 

 , black bands. Jardine and Selby supposed this specimen to be Temminck's 

 I Falco cristatellus, in the adult state ; this is however not the case, as may easily 

 i be seen from a comparison of the description of the last species in Dr. Jerdon'a 

 work. —Nat. Hist, Secretary,
