SCIENCE 



[N. S. Vol. XXV. No. 629 



have appeared on its pages. A very eclectic 

 notice is again offered, in which particulariza- 

 tion will be even more limited than was the 

 case in 1900. A tabulation of general classes 

 of subjects, number of papers published under 

 each, and the number of pages, figures and 

 cuts, in each volume, is here subjoined. It can 

 be expected that, in the wide circulation of 

 Science, many readers wiU welcome this gen- 

 eralized description of the Bulletins of the 

 American Museum. 



A comparison between this table and the 

 table of analysis of contents of this publica- 

 tion, for the first twelve volumes, shows an 

 increase in the papers on entomology and 

 vertebrate paleontology, continued activity in 

 mammalogy, a decrease in ornithology, and 

 generally elsewhere, conditions similar to 

 those preexisting. 



The bulletins show a tendency to increase 

 in size, and the appearance of new workers 

 as Drs. Matthew, Gidley and Hay and Pro- 

 fessor Wheeler, with others (Nelson, Duerden, 

 Loomis, Hussakof, Brown Van Duzee, Banks, 

 Miller, Brues, Bandelier) diversify the pages 

 with new authors, and animate them with 

 new treatments. Papers of very considerable 

 length are noticeable, as Part I. of VoL XV., 

 in Professor Boas's ' The Eskimo of Baffin 

 Land and Hudson Bay,' the extended essays by 

 Kroeber on topics furnished by the Arapaho 

 Indians, studies supported by Mrs. Morris K. 

 Jesup; and Dixon's contributions to the eth- 

 nology of California in the Huntington Ex- 

 pedition. 



The first article in Vol. Xm., by Dr. Allen, 

 discussed the mountain caribou of British 

 Columbia with especial reference to Mr. 

 Ernest Seton-Thompson's new species (i2. 

 monianus) and forms another contribution to 

 the often noted variability of the genus, and 

 contained the statement ' doubtless when 

 series of specimens of caribou from different 

 parts of Alaska, including the tundra dis- 

 trict west of the Mackenzie Delta, and from 

 different parts of the Northwest Territory, are 

 brought together, it will be found that the 

 caribous of the region north of the United 

 States are differentiated into quite a num- 

 ber of well-marked local forms, as yet unde- 



scribed.' Professor Whitfield describes some 

 interesting fossils {Beceptaculites, Halysites, 

 Heliolites) from the arctic, brought back by 

 Lieut. Peary. Mr. Stone contributes a nar- 

 ration, in part, of his adventuresome journey 

 along the coast of northern Alaska. A shell 

 gorget of Tarascan origin and certainly im- 

 portant, and an onyx jar from Mexico are 

 described by M. H. SaviUe, and the same in- 

 vestigator adds an important and readable 

 article on ' Cruciform Structures near Mitla.' 

 Professor Osborn furnishes a discussion of the 

 Phylogeny of the Ehinoceroses of Europe 

 which illustrates " the early separation, abso- 

 lute distinctness, and great age of numerous 

 phyla leading up to modern types." In im- 

 portance this article easily exceeds the asso- 

 ciated papers of this volume. The volume con- 

 tains also a very illuminative analysis of 

 variation in the meadow-lark by F. M. Chap- 

 man. 



In volume XIV. two new contributors ap- 

 pear, W. D. Matthew and J. W. Gidley, both 

 of whose names have since become very 

 strongly impressed upon American vertebrate 

 paleontology. Matthew's 'Additional Obser- 

 vations on the Oreodonta,' and J. W. Gidley's 

 ' Tooth Characters and Eevision of the Genus 

 Equus,' in point of originality and permanent 

 results are the most valuable papers in the 

 volume. Dr. Allen prepared a review of the 

 question of the relationship of the musk-oxen 

 of Arctic America and Greenland which also 

 contained an extended historical reference. 

 The same distinguished systematist included 

 in this volume a study on the North American 

 opossums. Dinosaur Contribution No. 6, by 

 Osborn and Granger, appears in this volume, 

 and Beutenmliller continued his painstaking 

 papers on the lepidoptera. A useful descrip- 

 tive catalogue of the Binney and Bland col- 

 lection of moUusks closed the volume with 

 six maps of distributional intensity, which 

 were something of a novelty. 



About this time an attempt was made to 

 segregate articles on one class of subjects in 

 single volumes, and volumes XV., XVII., 

 XVTII. were in this way devoted to ethnology. 

 These volumes are not yet completed and con- 

 tain laborious papers by Boas, Dixon,
