APPENDIX B. 



FAUNAL SUMMARY. TABLES SHOWING DISTRIBUTION OF SPECIES 

 DESCRIBED. 



All the described or figured fossils noted in this work are 

 included in the following tables. North America is divided into 

 faunal provinces for each system from the Cambric through the 

 Pliocenic, and the species are recorded in the province or provinces 

 where they are known to occur. The letters L, M and U in the first 

 column, refer respectively to lower, middle and upper ; the letter X 

 indicates that the species ranges more or less throughout the entire 

 system. When no letter is given, the exact range of the species 

 is not known. An asterisk (*) indicates that the species ranges 

 through more than one system. In that case the species is listed 

 separately under each system. The range given in the first column 

 refers to the known entire range, which may not be that for each 

 locality cited. 



The geographic and geologic ranges given in the table may some- 

 times differ from those of the same species in the text. In such a 

 case the range given in the table is to be regarded as the true one 

 based on more recent knowledge.
