FASCIOLOPSIS FULLEBORNI 247 



another), more compactly branched, broader and denser than in 

 Fasciolopsis buski. Ovary on right side, small, coarsely branched. 

 Uterus in broad, closely grouped coils, packed with ova anterior to 

 ovary. Vitellarian acini more numerous and somewhat differently 

 distributed. Eggs 150/4 by 80 //,, thin shelled. [H. B. Ward, who has 

 examined this species, and from whose account the above is mainly 

 taken, considers that it is a good species, although the differences 

 between it and Fasciolopsis buski are slight, while Odhner, who examined 

 the original species, is of the opposite opinion. J. W. W. S.] The 

 parasite appears to cause diarrhoea, wasting and occasionally jaundice. 



Habitat. Intestine of man. 



Distribution. China, common in some parts (Goddard). 



Fasciolopsis goddardi, Ward, 1910. 



Twenty-one to 22 mm. long, 9 mm. broad. Skin with spines 

 (Leiper). Uterus very closely coiled, most striking character is the 

 large size of the vitelline acini. Imperfectly known. 



Distribution. China (Shanghai). 



Fasciolopsis fulleborni, Rodenwaldt, 1909. 



The fully extended fluke is tongue-shaped, 50 by 14 mm. ; two 

 contracted specimens measured 40 by 15 mm. and 30 by 16 mm. 

 respectively. Skin without spines, with according to Leiper cephalic 

 cone not clearly denned. Oral sucker circular, 075 mm. in 

 diameter, slightly larger than that of Fasciolopsis buski. Ventral sucker 

 2'6 mm. in diameter (that of Fasciolopsis buski r6 to 2 mm.). Length 

 2-9 mm. (as in Fasciolopsis rathouisi), the excess of length over breadth 

 being due to the posterior elongated sac-like prolongation of the 

 sucker. Prepharyngeal sphincter present. Pharynx 0*7 mm. in 

 diameter. (Esophagus practically absent. Gut caeca similar to those 

 of Fasciolopsis buski. 



Testes regularly branched, separated by an incurving of the caeca, 

 the anterior occupying a smaller area than the posterior. 



Ovary very small, as in Fasciolopsis buski, on the right side. 



Shell Gland almond-shaped, 2-3 by 1-2 mm. In Fasciolopsis buski 

 it is round and smaller, i to 1-5 mm. in diameter. 



Vitellaria similar in distribution to those of Fasciolopsis buski, but 

 the acini are strikingly small. 



Cirrus Sac is the most characteristic feature of this species. It is 

 a powerfully built, convoluted sac standing out clearly on the body.
