ART. 16. 



BIRDS FROM NORTH CELEBES ^RILEY. 



48 



Dr. C. W. Richmond " has already pointed out that Icthyophaga 

 Lesson '^ is the proper generic term to be employed for this genus of 

 eagles, but he does not seem to have been followed by subsequent 

 authors. Ichthiaetus Lafresnaye^^ is preoccupied by Ichthyaetus 

 Sweeting ®<> and is a nomen nudum, anyway. 



These two specimens measure as follows : 



There appear to be some discrepancies in the descriptions of 

 this species that I have consulted, probably due to the age of the 

 specimens used for description. The above two specimens have 

 the base of the tail, except the two central feathers, mottled with 

 white, more pronounced in the smaller specimen and more noticeable 

 below than above. Indeed the white mottling above is confined to 

 the inner web of the feathers. They appear to be adult. Sharpe,*^ 

 Meyer and Wiglesworth,^^ and Kirke Swann^^ do not mention this 

 white mottling at the base of the tail in their descriptions but it is 

 mentioned by Blanford.** 



Family PANDIONIDAE. 



OSPEEYS. 

 84. PANDION HALIAETUS CRISTATUS (Vieillot). 



One male and one female, Tandjong Penjoe, February 24, 25, 

 1915. 



I have no Australian birds for comparison but the above two 

 specimens have the top of the head white with a dark narrow 

 nuchal stripe in the center, quite different from the more or less 

 heavily streaked heads of more northern birds; they also appear to 

 be somewhat smaller. The male measures: Wing, 418; tail, 207; 

 culmen from cere, 30.5 — the female: Wing, 440; tail, 227; culmen 

 from cere, 33.
