Lucas on a New Fossil Flightless Auk.' — On the basis of a nearly 

 complete humerus found in exca\ating a street tunnel at Los Angeles, 

 California, Mr. Lucas has founded the new genus and species Mancalla 

 californicnsis, an extinct species of auk which he believes to have been 

 flightless. He says: "The bird to which this humerus belonged was 

 more highly specialized, more completely adapted for subaquatic flight, 

 than the Great Auk, although the wings were not so extremely modified 



as those of the penguins The occurrence of a flightless auk at so low a 



geological horizon as the Miocene is of great interest, as indicating a 

 much earlier origin foh the family." — J- A. A.

 The authors state that one of the main objects in publishing the present list

 gained"; and that they regard it " as in no sense final, but only provi- 

 sional." Acknowledgments are made of indebtedness to pre\ious 

 publications on the birds of the State, and for much hitherto unpublished
