CHAPTER XIV. 
THE TANGANYIKA JELLY FISH. 
The remarkable organism, Limnocnida tanganyicce, or the 
Tanganyika jelly fish which originally caused interest to 
centre in the question of the nature of the aquatic faunas of 
the great African lakes, was first observed, as I have said, 
by Dr. Bohm and afterwards by Von Wissmann. Finally 
by the efforts of Mr. Frederick Moir, who forwarded osmic 
acid and spirit to Central Africa, Mr. Swann succeeded in 
preserving some specimens on the Lake. The material 
thus obtained was sent to Dr. Gunther at the British 
Museum, who in turn handed it for examination to his son. 
The result of this examination appeared later in two papers, 
a short general account of the animal’s anatomy published 
in “The Annals and Magazine of Natural History,” and 
some further details which subsequently appeared in “ The 
Quarterly Journal of Microscopical Science.” 
As these accounts have now been in the literature some 
years, it has appeared to me to be unnecessary to go into 
details with respect to the structure of the adult animal in 
the present work. It will suffice to say that the jelly fish is 
a true Craspidote Medusa, as Bohm originally described it ; 
that when adult it varies between the sizes of a one and a 
two-shilling-piece ; that it is during life nearly as flat as 
these respective coins, and that it carries its long tentacles
