three localities in that territory where such farming is carried on to 

 a greater or less extent. The possible animals that may be bred for 

 fur are the fox, mink, marten, otter, and beaver; but so far it has only 

 proved practicable with foxes and minks. Silver foxes are successfully 

 bred in the interior and fed on salmon and rabbits to a large extent. 

 Blue foxes are successfully raised along the coast, especially on cer- 

 tain of the islands. 



The paper was discussed by Dr. C. W. Stiles who called attention 

 to the prevalence of certain forms of hookworms in the dogs and foxes 

 of Europe and Alaska but seldom found in the dogs of the United States. 



The 550th regular meeting of the Biological Society of Washington 

 was held in the Assembly Hall of the Cosmos Club, Saturday, February 

 12, 1916, at 8 p.m., fifty persons being present. 



On recommendation of the Council, Walter P. Taylor, of the Mu- 

 seum of Vertebrate Zoology, Berkeley, California, was elected to active 

 membership. 



Under the heading Brief Notes and Exhibition of Specimens, L. O. 

 Howard called attention to the work lately done by Dr. W. V. King, 

 of the Bureau of Entomology, in demonstrating that Anopheles puncti- 

 pennis was a carrier of both tertian and aestivo-autumnal malaria 

 parasites. He exhibited lantern slides of this mosquito and photo- 

 micrographs of the stages of the malaria organism in this hitherto sup- 

 posedly harmless species of mosquito. 



Under the same heading W. L. McAtee gave some of his recent 

 observations on the vegetation of Virginia in the region south of 

 Washington. 



The first paper of the regular program was by Henry Talbott: 

 Nepigon. Mr. Talbott gave an entertaining account of a trip made 

 by himself and others to Lake Nepigon. The fishes of the lake and 

 neighboring region were especially dwelt on. Mr. Talbot's paper was 

 discussed by Dr. Howard. 



The second and last paper of the regular program was by Vernon 

 Bailey: Game and other mammals of the Yellowstone Park region. Mr. 

 Bailey gave a short outline of his recent trip through the Yellowstone 

 Park and the neighboring region, particularly to the south. The 

 ground covered was mainly off the tourist track. The speaker de- 

 scribed the beauties of the park from the viewpoint of the lover of 

 wild life; he called particular attention to the loss of fear of men by 

 wild life when protected from guns, dogsandcats; he called tonoticethe 

 thriving condition of herds of ruminants in the park and the successful 

 efforts now made to supply hay to the needy in winter, and to keep the 

 antelope from wandering out of the park. Mr. Bailey's communica- 

 tion was profusely illustrated with lantern slide views of the park and 

 of its wild life, especially the white-tailed deer, mule deer, elk, moose 

 (recently described as Alces shirasi), antelope, bison, some of the smaller 

 mammals and Canada geese.
