The Genus Fasciola 
Specimen No. 3, 23 mm. long by 3*5 mm. broad, is a small fluke of similar 
proportions to No. 2, but the cone is larger in proportion to the body. The 
condition of the specimen makes it difficult to determine. The uterus is 
large and with few coils; it contains some 
eggs. The space occupied by the testes is un¬ 
usually large, from the mouth to the posterior 
border of the testis area measuring about 
18 mm. The ventral sucker is not prominent. 
It is not possible to make out the alimentary 
canal. The yolk glands are normally arranged 
and the median commissures to the shell gland 
are visible. Proportion of length to breadth 
under 7 to 1. 
Specimen No. 2 is a type of the specimen 
figured by Cobbold but somewhat longer in 
proportion to the breadth than his figure. 
The average length of his specimens is given 
as 2 inches and as this type specimen is 
nearly 2J inches it may be taken as slightly 
larger than the average. In the largest speci¬ 
men (No. 1) the proportion of length to 
breadth is amazingly larger than any known 
fluke, and in the other specimens it is re¬ 
markably large. One can only look on the 
classing of these three worms in one species 
with grave suspicion until similar specimens 
are again found in the giraffe and their 
anatomy is accurately described. 
In the meantime the medium sized speci¬ 
men (No. 2) must be taken as the type of 
Fasciola gigantica. 
The material in my possession which bears 
on the specimens under consideration is de¬ 
scribed below, but only the important features 
are recorded.

Text-fig. l Text-fig. 2 The large cone passes insensibly into the 
body; in no case are “shoulders” more than 
slightly indicated. The body in every specimen tends to expand slowly to 
its greatest width at or about the posterior border of the testis area and 
ends in a very bluntly rounded tail. The ventral sucker is round and
