are between genera in Ornithology. One can hardly avoid the sus- 

 picion that Trinomialism is working this discrepancy. But we 

 must also remember that intensive study, such as our chosen sci- 

 ence is receiving, tends to discover differences where none were 

 known to exist before, while it is also likely to magnify really 

 slight differences. It is hard to draw the line. Former exper- 

 iences prepared us for the usual reprinting of practically the whole 

 Melospiza gi'oup. It is certainly a flexible genus or the contortions 

 it is periodically called upon to go through would have disrupted 

 it long ago. Forty proposed changes and additions were acted 

 upon favorably, and nearly a hundred cases are deferred. We see 

 no signs of the coming of stability in nomenclature, except the re- 

 port of progress which this supplement may be considered to be. 



PUBLICATIONS RECEIVED. 



Birds in their Relation to Man. By Clarence M. Weed and Ned 

 Dearborn. A Manual of Economic Ornithology for the United States 

 and Canada. J. B. Lippincott Company, Philadelphia and London.. 



The timliness of this new volume will ensure for it a welcome 

 cmong bird students everywhere. It is well illustrated in half- 

 tone3 and cuts with many new pictures of birds and insects. It is 

 printed on good heavy paper in twelve-point type, and the typogra- 

 phy is unusually good. 



The subject matter may be divided into four parts, the first seven 

 chapters being devoted to a general discussion of "Methods of 

 Studying the Food of Birds," "Development cf Economic Ornithol- 

 ogy,'" the food and amount consumed, "Birds as Regulators of Out- 

 breaks of Injurious Animals," of the different groups, in the reverse 

 order of the A. O. U. classification; the Conservation, Prevention 

 of Depredations and Encouragement of the Presence of Birds; and 

 finally an appendix giving the A. O. U. Model Bird Law, the Lacey 

 Bird Law, "Some Fundamental Principles of Bird Laws," "A Par- 

 tial Bibliography of the Economic Relations of North American 

 Birds," and Index. 



Into this volume have been gathered the many scattering ac- 

 counts of the food of birds, and some new information is given 

 about the food of several species. It is not assumed that every- 

 thing has been learned about the food of our birds, but it is hoped 

 that the bock will prove of some value to those who wish to learn 

 what the economic status of the different birds is. It is a welcome 

 addition to bird literature, and we have reason to thank the authors 

 for their timely presentation of the book. L. J.
