The above lists have been compiled chiefly from the writings 

 of Kner 1 and Bassani, 2 and the more recent memoir of De- 

 Allessandri (1910). These assemblages from the marine Keuper 

 of southern Europe are instructive as showing the continued im- 

 portance of the Semionotidse, and their accompaniment by 

 Ptycholepis and a single Crossopterygian genus different from 

 either our own Diplurus or the unique Heptanema of Perledo.

Compare also the lists given by Baron Achille de Zigno, in his " Pesci fossili di 

 Lumezzane in Val Trompia (Lombardia)." Mem. R. Accad. del Lincei, 1891, anno 

 287, p. 5. A comparative table of the Raibl and Lombardy section will be found at 

 page 325 of Arthaber's work on the Alpine Trias, in Freeh's " Lethaea Geognostica."
