FASCIOLOPSIS FULLEBORNI 



569 



Morphology.— It is a large, thick, brown, smooth trematode, 24 to 70 milli- 

 metres in length and 5-5 to 14 millimetres in breadth. The oral sucker and 

 acetabulum are in the proportion of 0-5: 2-0. The pharynx is globular, and 

 there is a prepharynx, with a sphincter. The oesophagus is short, and the 

 intestinal caeca are not branched, and extend ^ ^ 



to the posterior border. The genital pore is 

 situated anteriorly to the acetabulum, but the 

 most remarkable feature is the very long 

 cirrus, about one-fourth the length of the 

 body. The testes lie posteriorly, with the 

 ovary and the uterus in front. The yolk glands 

 are extensive, like those in F. hepatica. 



Life- History. — The eggs are 0-12 to 0-13 

 millimetre in length and 0-077 O'^S in 

 breadth, and the larval stages are said to 

 occur in shrimps. 



Habitat— The intestine of the pig and 



man. 



Pathogenicity,— It is beheved to cause 

 dysenteric diarrhoea, wasting, and jaun- 

 dice at times. 



Faseiolopsis fulleborni Rodenwaldt. 

 1909. 



History.— This worm was discovered 

 and described by Rodenwaldt in 1909, 

 being found in the motions of an Indian 

 in Hamburg. 



Morphology. — The parasite is very large, 

 measuring from 30 to 50 millimetres in length 

 and from 14 to 16 millimetres in breadth. 

 The oral sucker and acetabulum are in the 

 proportion of 0-75 to 0*6. There is a prepharynx 

 and pharynx, but no oesophagus. 



The intestinal caeca are long and wavy, and 

 extend to the posterior end. The genital aper- 

 tures lie in front of the acetabulum. 



The cirrus sac is very long and well developed, and the testes lie behind the 

 ovary and the ootype. The latter is much larger than in F. buski, and is oval 

 instead of being round. The yolk glands extend from the acetabulum to the 

 posterior end of the body, being situated laterally. The excretory vesicle 

 is well developed. 



The eggs measure o-i millimetre in length by 0-073 millimetre in breadth. 



Habitat. — Intestine of man. 



Pathogenicity.— The patient harbouring it was suffering from 

 fever, which had been diagnosed as typhoid.

Kwan's Fluke ( =F. goddardi ?). 



Under this term Heanley has described a trematode found by Dr. Kwan 

 King Hung in a child in the island of Hong Kong. 



Morphology. — In length it is 2 inches, in breadth I inch. The cuticle pos- 

 sessed spines. The intestine was not clearly seen, but the caeca were un- 

 braached. The testes were large and placed one behind the other. The
