2. Tcenia marginata, Batsch, 1786. 

 Syn. : T. e. Cysticerco tenuicolli, Kuchenmeister, 1853. 



This species, which in structure ^resembles Tesnia solium, lives in the 

 intestine of the dog and the wolf. It attains 1-5 4 m. in length, pos- 

 sesses a double crown of thirty to forty hooks ; on an average thirty- 

 six to thirty - eight hooks, 

 and in its cysticercus stage 

 (Cysticercus tenuicollis} lives 

 in monkeys, pigs, sheep and 

 oxen. 



It is included in this work 

 because, according to one 

 statement, Cysticercus tenui- 

 collis is supposed to have 

 Fir, i66.-Large and small booklets of Tvnia ^ Qn observed in man' in 

 marginal*. 280/1. (After Leuckait.) North America - B t the 



case is not quite certain, as 

 the number of hooks was 



less than in Cysticercus tenuicollis, and coincided with Cysticercus cellulose 

 although the size of the cysticercus]! appeared to point to Cysticercus 

 tenuicollis. A yet earlier statement of Eschricht, that C. tenuicollis had been 

 observed in Iceland in the liver of a man, is undoubtedly due to an error. 



3. Tcenia serrata, Goeze, 1782. 



This parasite attains a length of from 0-52 m., possesses a double 

 crown of thirty-four to forty-eight (mostly forty) hooks. It lives exclusively 

 in the intestine of the dog, the corresponding cysticercus (Cysticercus pisi- 

 formis} living in the abdomen of the hare and rabbit. We mention this 

 species with all reserve amongst the parasites of man, because Vital- states
