SPECIES OF NEOSIGNORETIA 



a. Pygidium without pectinae or plates on lateres. 

 b. Pygidium with three pairs of lobes. 



c. Pygidium with median pair of lobes notched, 

 d. Pygidium with plates in median incisura; median pair of 

 lobes wide, others rudimentary, all small; plates long and 

 slender, sharp, conspicuous, distinctly longer than lobes, ar-
