438 ANSERES. — COLYMBID^. 



said to burrow to the extent of ten feet. Nothing 

 is known of its habit of feeding. E. M'Qeachy, 

 Esq., Crown Surveyor for the county of Surrey, 

 first informed me of the existence of such birds. 

 He had himself taken them from their burrows. 

 The facts have also been assured to me by other 

 observers." A specimen of this bird is said to be 

 in the possession of Greorge Atkinson, Esq., of New- 

 castle-on-Tyne, who, in answer to an application from 

 me, kindly promised me a particular description ; but 

 other engagements, probably, have not yet afforded 

 him the necessary leisure.
