Limnocardiiim, represented at the present day in the Caspian by the subgenera 

 Didaciia and Monodaciia was an abundant form in earHer times, and iii some instances

 great African lakes, 



It is to bj hoped that the eminent author mav ultimately see his way to combining

 to S iiidbjrger's monograph already cited above.
