302 THE TUBE-NOSED SWIMMERS — TUBINARES. 



The type specimen of the Fuffiiuts amaurosoma of Cones was taken off the coast ot Cape San 

 Lucas. The National Museum also possesses specimens from the coast of Chili. According to 

 Buller, it is extremely abundant in the neighborhood of Stewart's Island and along the adjacent 

 coast of New Zealand. 



The only accounts I can find touching the nidification of this bird are — the state- 

 ment of Mr. Buller that its egg is white, with reddish-brown stains, and measures 

 3.25 inches in length and 2.00 in breadth ; and the Notes of Mr. Travers, quoted by- 

 Mr. Dresser, that this Shearwater is common all around the coasts of the Chatham 

 Group, where it burrows in peaty ground a horizontal hole, from three to four feet 

 deep, and turning slightly to the right or left. At the end of this hole it forms a 

 rude nest of twigs and dead leaves. Only one egg is laid, and the male is said to 

 assist in incubation; and the parent birds are very savage while on the nest, biting 

 and scratching those who molest them. The old birds roost on the shore, and the 

 noise they make during the whole night is described as being something absolutely 

 frightful. Taken out of their holes, they fluttered about on the ground for some time 

 in a confused manner before they made for the sea.
