William P. Turnbull, Ll.D., remarks (' Catalogue of Birds of East 

 Pennsylvania and New Jersey/ 1869, p. 47) : — 



'^Labrador Duck QCamptolcemus labradorius; Sand-shoal Duck; Pied

 express my thanks : — 



To Dr. Giinther and the Trustees of the British Museum, for the per-

To Mr, Thomas J. Moore and the authorities of the Liverpool Museum, 

 for sending their immature one to London to be drawn (it appears as the third 

 in the illustration). Mr. Moore assisted me greatly. 



To Professor Newton, for the loan of the (unique .^) sternum of the Pied 

 Duck, with others (of which I have given representations) which form part 

 of the large collection made by Messrs. Alfred and Edward Newton, now in 

 the Museum of the University of Cambridge. (This valuable bone was sent 

 to the above gentlemen by Col. Wedderburn as that of the male bird killed 

 by him in the harbour of HaUfax, Nova Scotia.) I have also to thank Mr.
