146 PROF. W. PETERS ON T.ENIA FROM RHINOCEROS. [Feb. 21, 



that there was an exactly similar pair of tusks in the Museum of the 

 Royal College of Surgeons, but that he had hitherto sought in vain 

 for any information as to the name of this extraordinary parasite. 



The following papers were read : — 



1. Note on the Tarda from the Rhinoceros, lately described 

 by Dr. J. Murie. By Professor W. Peters, F.M.Z.S. 



[Eeceived February 1, 1871.] 



The very remarkable large cestoid worm, described doubtfully by 

 Dr. Murie as a new species (Taenia magna, P. Z. S. 1870, p. 603), 

 and based on imperfect specimens from the Indiau Rhinoceros, ap- 

 pears to be the same which I found in the small intestines of the 

 Rhinoceros africanus, and of which I gave in the monthly reports 

 of the Royal Berlin Academy for 1856, p. 469, the following dia-

"TAENIA GIGANTEA, n. Sp. 



" Caput magnum, latum, glohosum, quadrilobum, rostello brevi ro-

 subnullum ; corpus crassum lanceolatum ; articuli brevissitni et 

 latissimi, marginibus postice excisis, angulis obtusis ; aperturce 

 genitales maryinales secundce ; penes Jiliformes, limbo globoso 

 cincti. 

 "Long, tota 0*1 20 m.; art. max. 0-003; lat. max. 0'027-0-029 ; 

 lat. cap. 0-006; colli 0-005. 



" Hab. Rhinoceros africanus, Camper; in intestino tenui. — 

 Mossambiqne." 



The accurate figures given by Dr. Murie of the individuals of the 

 worm in their different state of growth agree so perfectly with the 

 African specimens that I cannot hesitate to regard tbem as belong- 

 ing to the same species.

I subjoin a figure of the head (the scolex), in case it might be
