p) Die Mutterlarve bildet junge Stammlarven durch paramediane Làngsteilung. 



I Von Zeit zu Zeit wird das Hinterende durch Querteilung abgeschniirt und 



I geht zu Grunde. 



h) Die jungen Stammlarven entwickeln sich zu symmetrischen Stammlarven. 



3. Der A. formuliert eine Hypothèse, nach welcher die lateralen Scolex- 

 jganglien fur die Teilung verantwortlich wàren. 



1. The Tetrathyridia of Mesocestoides corti Hoeppli, 1925 multiply asexually 

 jby fissiparity. There is no budding. 



2. A. distinguishes 3 phases of asexual multiplication: 



a) The symmetrical founder larva gives rise by partial antero-posterior fission 

 î to two identical mother larvae, the original posterior part being shed and 



eliminated. Both mother larvae possess two original suckers. 



b ) Production of young founder larvae by paramedian fission of mother larvae 

 and élimination of the hind part. 



^) Development of the young founder larva into symmetrical founder larvae. 



' 3. A. proposes the hypothesis that the latéral ganghons of the scolex are 

 responsible for fission.
