DIGENETIC TREMATODES 29 



Hosts : 



Morgan and Hawkins (1949) discussed this form and gave additional hosts 

 and distribution as well as the life history which is much like Fasciola hepatica. 

 Skrjabin (1948) reviewed the morphology and figured the developmental stages 

 but not the adult worm. Slusarski (1955) rejected the genus Fascioloidcs and 

 thought that the name should be Fasciola magna. Life history studies on Fas- 

 cioloides magna include those of Campbell and Todd (1954, 1955, 1956), Griffiths 

 (1955), and Wu and Kingscote (1953, 1954).
