other material belonging to the U. S. National Museum and the American 

 Museum of Natural History. 1 A large amount of material is illustrated 

 in half-tone, comprising 578 figures of bones or fragments arranged on 

 35 plates. 



Colymbus parvus, Polilymbus magnus, Phalacrocorax macropus and Olor 

 matihewsi from the Oregon Pleistocene are described as new. 



In a second paper additional collections belonging to the same institutions 

 are described. Ninety-six specimens are figured on nine plates. Diatryma

Hahn on the Future of the North American Fauna. 2 — The late 

 Dr. Hahn whose unfortunate death was mentioned recently in ' The Auk ' 

 has contributed a suggestive paper under the above title. While he has 

 in mind animal life as a whole most of his remarks refer equally well to 

 birds and he constantly quotes birds as examples. We cannot do better 

 than to quote his own resume in order to give an idea of the manner in 

 which he has treated the subject. "Briefly the tendency of the North 

 American fauna is toward mediocrity. Large species are giving way 

 to small; bizarre species to commonplace. Marsh-loving and forest-lov- 

 ing animals disappear with the advance of civilization, and grass-loving 

 species that are able to exist in fence rows and pastures survive. Animals 

 that yield products of value vanish before the hand of man; likewise his 

 enemies are destroyed unless protected by small size and great fecundity. 

 Courage and the social instinct are at a discount and cunning and timidity 

 at a premium." — W. S. 



Doolin's ' Field, Forest and Stream in Oklahoma.' 3 — In this attrac- 

 tively printed and well illustrated volume, Mr. Doolin sets a high standard 

 for game wardens' reports. As he says in his ' foreword ': " An annual 

 report which recorded merely receipts and expenditures would convey no 

 information such as might lead the public to an understanding of the prob- 

 lems and difficulties that confront those who are desirous of saving all 

 useful forms of wild bird and animal life from extermination. It is 

 especially the purpose of this report to ask the people of Oklahoma for 

 their fullest co-operation in the protection and conservation of disappear- 

 ing wild life in this state."
