REVIEWS AND BOOK NOTICES. 



Professor Meek, in a series of critical articles in the American Jour- 

 nal of Science and Arts, commencing in March of the present year, 

 has reviewed many of the fossil species figured and described in the 

 fifth volume of the Geological Survey of Illinois. 



He suggests that Actinocrinites ddicatiis and A. penicillm, j)]. xi'u., 

 fig. 2, are probably the young of the genus Strotocrinus, which latter 

 genus holds a higher position in the scale of development than the 

 former. That the genus Zeacrinus (Troost) is probably only a synonym 

 of Hydreionocrinus (Koninck). That Fusilina gracilis and F. ventri- 

 eosa, pi. xxiv., figs. 7, 8, are only varieties of F. cylindrica. That 

 Aviculopecten neglectiis (Geinitz), pi. xxvi., fig. la, b, c, d, should be 

 placed in a new genus. He, therefore, i^roposes to write the name 

 Fuchondria negleda (Meek). That fig. 8, pi, xxvi., is an Avicuhpeden 

 carhoniferus (Stevens), instead of Xucula jmrva, as stated by mistake. 



His criticisms upon the crinoidea are the reflections of a learned 

 paleontologist, and must be studied in connection with said fifth vol- 

 ume, in order to be fully appreciated. 



The legislature of Ohio, about the close of the last session, provided 

 for publishing two more volumes of the Geological Survey. The 

 statutory provision is as follows : 



" For preparing for publication, engraving, printing, binding, and 

 publishing parts one and two of the second volume of the report of 

 the Geological Survey of the State, sixty thousand dollars, to be 

 expended under the direction and supervision of the supervisor of 

 printing and secretary of state ; and the secretary of state is hereby 

 authorized to purchase a sufficient supply of super-royal paper to 

 provide fly-leaves for said volumes ; two of said reports, to be paid for 

 out of this appropriation." 



It is to be hoped that the work will be very carefully prepared. 



We have received a copy of " Guyot's Grammar School Geography," 

 just published. It contains numerous maps, very carefully prepared 

 and neatly executed, presenting a better view of the geography of the 

 surface of the earth than is to be found in any atlas of equal size yet 

 published. It contains also a vast amount of information not readily 

 obtainable elsewhere, and, taken all in all, is a school geography of 

 inestimable value, and one that we do not hesitate to recommend for 

 general use in the higher grades of public schools. Published by 

 Scribner, Armstrong & Co., of New York, at $2. C. B. Ruggles, 

 agent for Ohio, Kentucky, and Tennessee, care of Geo. E. Stevens Si 

 Co., 39 West Fourth street, Cincinnati, Ohio.
