pore. The openings of the cirrus and vagina are situated at the 
side. Yolk-glands double, situated laterally and consisting of 
numerous follicles. Ovary situated behind the shell gland. Adult 
in reptiles and birds. 
Genus Ichthyotaenia, Lonn., 1894. 
Scolex armed with four suckers and often a fifth apical sucker.

fishes, birds and reptiles. 
Ichthyotaenia (Acanthotaenia) nilotica, Beddard, 1913. 
ZEV £945 Varanus bengalensis. Balugaon, T. Southwell. Numerous 
Orissa. specimens. 
Our specimens agree in every detail with the excellent descrip- 
tion given by Beddard of this species in the P.Z.S., London, 
March 1913, and to this paper the reader is referred for a discus- 
sion of the relationship of the genus. 
The lizard was caught near a small freshwater ditch 8 miles 
north of Balugaon, and about 3 miles from the west shore of the 
Chilka lake.
