The following Bulletins have been issued : — 



No. 87, A sy?iopsis of American Fossil Brachiopoda, includ- 

 ing bibliography and synonymy, by Charles Schuchert, pp. 1-464, 

 189*7. The author recognizes 2053 known species of Brachiopods 

 from the sediments of North and South America, 1922 ol which 

 are known from North America. The statistics of original 

 description, geological range, geographical distribution and sys- 

 tematic classification, are fully expressed in carefully prepared 

 lists. The biological development is discussed in a chapter by 

 the author, and Prof. Charles E. Beeeher contributes a special 

 chapter on the morphology of the bracbia. The author's exhaust- 

 ive study of the chronological history of the Brachiopods con- 

 firms the law of the rapid differentiation of a type of organisms 

 at its beginning, announced by Hyatt in 1883 from a study of 

 Cephalopods, and elaborated in the case of Brachiopods by the 

 present writer in 1895.
