- SUNDERBUNDS (PLAGIOTENIA GIGANTEA, 
PETERS).* 
In 1856+ Dr. Wm. Peters described a tapeworm which he found in 
an African Rhinoceros from Mossambique, which he named Tenia 
gigantea. 
In 1870¢ Dr. Murie described the adult proglottides of a tape- 
worm passed by an Indian Rhinoceros (Rhinoceros wnicornis) living 
in the Society’s Gardens at the time, which he named Tenia magna ?. 
Tn 1871§ Dr. Peters communicated to the Society a Note on the 
results of a comparison of his specimens of Tenia gigantea with 
Dr. Murie’s description and figures of his Tenia magna?, showmg 
their identity, and suggesting the generic name Plagiotenia for the 
During this summer I have had the opportunity of eviscerating 
a half-grown female of Rhinoceros sondaicus, from the Sunderbunds, 
which had been a little more than six months in this country. In the 
- commencement of the colon I found three tapeworms with their 
heads (scoleces), together with several detached groups of proglot- 
tides, || these latter being quite undistinguishable’ from those figured 
by Dr. Maurie, in form as well as size. 
Dr. Peters has figured the scolex in his species, which is evidently 
in a powerfully contracted condition, to which one of my three 
specimens closely approaches. My other two specimens are not so, 
and, as a result, differ so much im appearance that I subjoin a figure 
of one of them. :

|| In his account of his specimens Dr. Murie has most curiously mistaken the 
groups of proglottides (which he figures) for single segments.
