NOTICE OF SOME ENTOZOA. 



Distoma crassum, Busk. Cobbold : Proc. Linn. Soc. i860, vol. 



V, p. 5- 



Mr. Busk, an English surgeon, in 1843 announced the occurrence 

 in the intestine of a Lascar or Hindoo seaman, who died in London, 

 of a large species of Fluke, for which he suggested the name of 

 Distoma crassum. Fourteen specimens obtained ranged from 4 to 6 

 cm. long by 1.7 to 2 cm. broad. The same parasite has .since been 

 reported as occurring in Chinese and in Europeans living in China.
