ACCIPITHES. 

 FALCONID^E. 

 AQUILINE. 

 Genus LOPHOTRIOBCHIS. 

 Bill curved more suddenly from the base than in Nisaetus, less stout, and with the tip not 

 so prolonged ; margin not prominently festooned. Nostrils circular, rather small, and placed near 

 the edge of the cere. Wings moderate, reaching, when closed, beyond the middle of the tail ; 

 the 4th and 5th quills subequal and longest, or the 5th shorter than the 4th. Tail moderate, 

 broad at the base, rounded at the tip. Tarsus as in Nisaetus ; middle toe long, with the claw 

 rather short ; lateral toes nearly equal, but with the inner claw nearly as long as the hind one. 

 Head crested ; the feathers short, broad at the base, and pointed at the tip, forming a wedge- 

 shaped crest, which originates above the occiput.

Adult male. Length to front of cere 19'5 to 205 inches ; culinen from cere 1*0 to l'l ; wing 14'2 to 15 - 5 ; tail 8 ; 2 to 

 9 - ; tarsus 2-7 to 3"0 ; mid toe 2-0 to 2-15, its claw (straight) 085 to l'l ; inner claw (straight) 1*3 ; height of bill 

 at cere 0-5 to 0-55. Expanse (of one with wing of 14'5) 45 - ; weight of the same If lb. 



A great disparity in size exists betwen the sexes in this species, but males also differ much inter se in this respect. 

 The above dimensions are taken from a fair series of Indian, Ceylonese, and Malaccan examples. The wings of 

 four Ceylonese males examined measure 14-2, 14-5, 13-5, and 15-0. 



- Adult female. Erom Mr. Hume's Darjiling specimens (' Stray Eeathers,' vol. i. p. 311). Length 24-0 to 29-0 inches ; 



* The article here referred to merely has these initials appended to it, and some doubt exists as to whether they 

 refer to G. Sparre or Geoffroy St.-Hilaire. Mr. Sharpe has adopted the latter in his ' Catalogue of the Accipitres.' I 

 observe that, throughout the ' Mag. Zool.,' St.-Hilaire either signs his name in full or uses the abbreviation " Geoffroy 

 St.-H. ; " and I think there is no reason to infer that had he been the author of the two descriptive articles (Astur hieneri 

 and Pica mystacalis) in the volume for 1835, which are signed " G. S.," he would have used these initials instead of his 

 usual signature. In the Boy. Soc. Catalogue, vol. v., these two identical articles are referred to as written by G. Sparre ; 

 and, in all probability, this is the correct determination of their authorship.
