BIRDS OF ICELAND 143 



the breeding-grounds of this species, as far as they are 

 known, are in the Southern Hemisphere {e.g. the 

 Chatham Isles, off the east coast of New Zealand). 

 The fishermen off Iceland should be induced to collect 

 specimens of the various 'Scrofas,' as definite informa- 

 tion upon them is much wanted.]

 Manx Shearwater. 



Native name: ' Litla Skrofa.' The meaninii' of this 

 name is obscure ; ' skrof ' means ' loose ice.'

 cliffs, for nidificatiou.

 parts of a sooty brown, underparts white, with dusky 

 scribblings on the sides of the neck and breast. Length

 thing small it can catch, or find dead, on the suriace ol" 

 the sea.
