SCIENCE. 



[N. S. Vol. XI. No. 282. 



Chapman, seems particularly interesting. 

 The volume closes with a second contribu- 

 tion on the Geology of Lake Champlain, by 

 Professors Brainard and Seely, in which the 

 Chazy beds of that instructive region are 

 especially discussed. 



Bulletin nine contains twenty-four ar- 

 ticles and was a very exhaustive display of 

 the scientific activity of the corps of re- 

 search in the Museum. Some papers were 

 of exceptional merit as Dr. Wortman's ad- 

 mirable review of the Ganodonta, a sub- 

 order of the Sloths, Dr. Matthew's revision 

 of the Puerco Fauna, and Dr. Boas' Decora- 

 tive Art of the Indians of the North Pacific 

 Coast. 



In the first Dr. Wortman established 

 the strong probability that the sloths of 

 South America were derived from the 

 Ganodonta of North America ; in the sec- 

 ond Dr. Matthew revised the Puerco Fauna, 

 and accentuated the ' entire distinctness 

 of the species of the upper and lower beds,' 

 and in the third Dr. Boas painstakingly 

 analyzes the scheme, motive, and meaning 

 of the conventionalized and derivative deco- 

 rative art of the Indians of the North Pacific 

 coast of America. 



The systematic and descriptive papers of 

 J. A. Allen, Frank M. Chapman, William 

 Beutenmiiller, were continued. Professor 

 Osborn contributed an authoritative paper 

 on ' The Huerfano Lake Basin, South- 

 ern Colorado, and its Wind Eiver and 

 Bridger Fauna.' Professor Whitfield pub- 

 lishes in this volume of the Bulletin a 

 paper of considerable interest, being a de- 

 scription of species of Rudistse, a remark- 

 able group of Lamellibranchs or bivalves 

 which are only known from the Cretaceous, 

 these here described by Professor Whitfield 

 coming from Jamaica. Professor Whitfield 

 contributed a second paper on the peculiar 

 genus Barrettia which Woodward, who in- 

 stituted the genus, considered, though with 

 hesitation, as a bivalve shell. Professor 



Whitfield reverts to Woodward's alternate 

 suggestion that they might be corals, and 

 delicately emphasizes the considerations 

 favoring this view. 



A paper of zoological importance was de- 

 voted to a preliminary description of a new 

 mountain sheep ( Ovis Stonei), by Dr. Allen. 

 This attractive ruminant was obtained on 

 the headwaters of the Stickeen Eiver, 

 British N. W. Territory, near the Alaskan 

 boundary, at an altitude of 6500 feet. 

 Color, size and character of horns seem to 

 distinguish it as new. 



This volume of the Bulletin contains a 

 description of an extraordinary Terra Cotta 

 figure from the Valley of Mexico which pre- 

 sents a life-size figure of a singing man, 

 with arms extended and mouth opened, 

 dressed apparently in armor. This reallj^ 

 efi'ective and striking relic was described by 

 Mr. Marshall H. Saville. 



Other papers by Juan Vilaro and Tarle- 

 ton H. Bean conclude the volume. 



The tenth volume of the Bulletin con- 

 tains a very valuable revision of the Red 

 Squirrels or Chickarees by Dr. Allen, which, 

 in a subject of great difiiculty, must rank 

 high amongst these reconstructions of this 

 phylum. Dr. Wortman produced for this 

 volume a masterly study of the ' Extinct 

 Comelidce of the U. S.' It perhaps may 

 rank higher than any of this writer's con- 

 tributions to these bulletins. The con- 

 clusions are fragmentary, but the light se- 

 cured was concentrated upon a diflicult and 

 intricate theme. Professor Osborn con- 

 tributed five papers on vertebrate paleon- 

 tology of varying interest, but all of scientific 

 importance. To a less technical scrutiny 

 the notes on the great Dinosaur ( Camara- 

 saurus) seem the most interesting. Mr. 

 Beutenmiiller continued his most useful 

 diagnoses of insects (Lepidoptera) with 

 especial reference to those near New York. 



Dr. Lumholtz furnished notes on the 

 Huichol Indians of Mexico, and, in con-
