 regarded as, entitled to first place follows immediately 

 after the otlier, so that both will be found together. 

 Obsolete names are set off from the others by a dash 

 and those regarded as misapplied are placed in paren-

When the genus has a common generic name, it 

 is placed in the line with the technical term. In gen-

 purpose of this book which aims to record only the 

 names current in common speech. It is to be remem-
