160 CAMBRIAN BEACHIOPODA. 



List of genera and subgenera, alphabetically arranged, giving number of species occurring in the different types of sediment. 



LOCALITIES. 



The following list gives all known data concerning all localities from which fossils described 

 in this paper have been obtained. After most of them refei'ence is given to the pages on which 

 their stratigraphic position is shown (pp. 124-159) . Those that are without references are more or 

 less isolated places for which stratigraphic data are lacking and which are without near neighbors 

 to which they may be profitably compared. An asterisk (*) placed before the name of a species 

 indicates that the place from which it is cited is its type locality. In localities 1-227 and 

 C1-C75 the Brachiopoda are not accompanied by author names, but for purposes of identifica- 

 tion the author names follow all other listed species. In localities 300 to 396z all the listed 

 species are accompanied by a reference to either the place of citation or the museum in 

 which the specimens are located. In all Usts the Brachiopoda are placed first. 



Numbers 1-227 were assigned to the different localities represented m the United States 

 National Museum at the time of their accession and indicate distinct faunules. Numbers
