 (/. M. Macotm.) 



Breeding Notes. — It comes to the Pribilof islands early in 

 May, mute and silent, locating its nest in a deep chink or crevice 

 of some inaccessible cliff, where it lays a single tgg, of a pure 

 white colour and oblong-ovate in shape, on the bare rock or earth. 

 {Elliott.) On Walrus island they lay their solitary egg under the 

 boulders like the puffins. The burrows on St. Paul island, as far 

 as I saw, were excavated in the volcanic cinders overlying the 

 rocky bluffs so that the entrance was always at the edge of the 

 cliff with the rock as a floor. (Palmer.)
