In as far as the present data are concerned there is adequate 
proof that all of the species of Fasciola sensu stricto exclusive 
of F. hepatica belong to the same species, F’. gigantica Cobbold 
1856. With this view Blanchard (1895:733) (1) and Stephens 
(1916 :244) (2) are in accord. 
Fasciola gigantica, which has been regarded as a parasite of 
man, is found in a great variety of ruminants. The present 
record supports the view that it is more widely distributed than 
had been previously believed. 
Paramphistomum anisocotylea sp. nov. Plate 1, fig. 3. 
This new species of amphistome, for which I propose the name 
Paramphistomum anisocotylea, was taken from the same host, 
Bubalus bubalus, from which Fasciola gigantica was secured. 
The fluke is ovoid in shape, measuring 6 to 6.3 millimeters long 
by 3.5 to 4 millimeters wide. It has a conspicuous acetabulum 
with a diameter somewhat greater than half the animal’s length 
(3.1 to 3.4 millimeters). The fluke is uniformly aspinose. 
The oral sucker with a diameter of 0.85 millimeter is directed 
anteroventrad. A short pharynx without pockets lies immedi- 
ately above the oral sucker and leads into a short cesophagus. 
The czca are inflated, sausage-shaped pouches, which extend 
to the mid-region of the acetabulum. 
The testes lie in tandem arrangement between the odtype and 
the metraterm. They are large, subovoid to rhomboid in con- 
tour, with small vasa efferentia leading anteriad toward the 
genital pore. The ovary is a small oval body situated immedi- 
ately to the right of the odtype and is connected with the latter 
by a short oviduct. Vitellaria extend from the region of the 
oral sucker to the posterior half of the acetabulum. The folli- 
cles are large and are spread out in a patelliform pattern. 
Short vitelline ducts connect these follicles with the odtype. No 
seminal receptacle has been found, but a Laurer’s canal is clearly 
made out. The odtype is surrounded by a spheroidal mass of 
shell glands. Leading out of the odtype is a very small uterus, 
which runs forward to the anterior region of the acetabulum 
where it enlarges and at the same time begins to coil. After 
a complicated series of serpentine twists it proceeds to the genital 
pore. 
The matured eggs measure from 140 to 160 » in length by 
70 to 85 » in width with an average of 150 by 80 pz. 
Paramphistomum anisocotylea differs in size, relation of the 
genital organs, and in other particulars from the previously de-
