 dimensions : — Total length about 31 inches ; bill, 

 from the gape 1^ ; height at the base ly^; wings 14 ; 

 tail, beyond, 10^ ; ditto, from the base 13 ; tarsus 4 ; 

 ' hind toe and claw 1 ^ ; middle ditto 3^ ; lateral ditto ^-j\,' 

 The tertial quills are as long as the primaries ; the 

 sixth quill is the longest. Tail rounded : toes half- 

 webbed for about ^-^ of an inch from their base.
