In discussing Mr. Pierce's paper, Mr. McAtee called atten- 

 tion to the fact that Mr. Pierce's examinations with negative 

 results of the stomachs of mourning doves which were sup- 

 posed to be eating ants confirmed previous findings regarding 

 this bird. Mr. Schwarz had examined about 220 stomachs 

 without finding any insects, and the Biological Survey of 

 the United States Department of Agriculture had examined 

 more than 250 with almost the same result. The most inter- 

 esting animal remains in dove stomachs were apparently 

 weathered segments of millipeds, which indoubtedly were 

 parts of long-dead animals, taken perhaps in lieu of gravel. 

 This called to mind another observation which definitely 

 proves that dead insects are sometimes taken, and which 

 furthermore has bearing on the habits of ants. Two specimens 

 of Serial taken from the stomach of a roadrunner (Geococcyx 

 California)! us} collected at Seaside, California, had the weath- 

 ered appearance noted above and were in fact mere empty 

 hulks. In the abdominal cavity of one specimen were eight 

 Momorum muriatum and in the other two. These little 

 ants were in perfect condition, which proves they were 

 in the bodies of the beetles when swallowed by the bird.
