872 Birds of Celebes: Anatidae. 



From its quieter coloration, D. guttata miglit be taken for a simpler type 

 of Tree Duck than its fellow-species, D. arcuata; yet, from the circumstance 

 that the flank-feathers of the young of D. guttata present the longitudinally 

 striped appearance seen in the other bird as an adult, it is probable that the 

 round white spots of D. guttata are a peculiarity of recent origin. 



GENUS ANAS L. 



In the typical Wild Ducks the culmen is longer than the tarsus and about 

 equal in length to the head , much broader than deep as measured across the 

 nostrils; the tarsus transversely scutellated on its lower part in front, the hallux 

 less than half its length; a broad metallic speculum on the secondaries, the 

 shortest of which are about half the length of the wing, or a little more. Its 

 larger size and relatively larger bill afford the best means of distinction from 

 Nettion. The males of some species very different in coloration from the females.
