 ''According to tbe Indians, tbe Boat-bill, Cancroma cochlearia, 

 lavs in March, but I have never seen its eggs." 



Mr.Barrington Brown (Canoe and Camp Lite, p. 257) remarks : — 

 "A Wallaba bird of a greyish colour, with large boat-shaped bill. 

 These birds are nocturnal in their hab'ts, roosting in trees over 

 swamps during the day, where they utter a curious frog-like 

 call." 



Mr. J. J. Quelch (Timebri (2) ii. p. 367) writes: — "It was 

 disappointing also to find that all the Boat-bills were in immature 

 plumage. Xot a single specimen was crested with the remarkable, 

 long, black plumes that give so striking an aspect to the bird. 

 In place of tliese there was a bluish-black tuft of down, both on 

 the white and on the younger reddish-brown specimens.'"
