are large and sinuous, and charged with spherically- 

 shaped eggs. One quite noticeable feature in this 

 parasite is, that the articulations, after separation, 

 become larger than the entire Tsenia (Moquin-Tan- 

 don). 



This parasite, in the adult state, is found in large 

 numbers in the dogs of Iceland ; but whether in man, 

 except as the " hydatid," is by some authorities con- 

 sidered doubtful. 



8. Tcenia cucumerina (T. elliptica, T. canina) is 

 common to dogs and cats, and has been stated to have 

 been found in the human body (Eschricht, Leuckart), 

 although Moquin-Tandon considers this as doubtful. 

 The scolex of this form is unknown. Dr. Weinland 

 suggests that it may be found in flies, which dogs are 

 so eager to catch and swallow. 



9. Twnia lophosoma. For a description of this 

 entozoon, we are indebted to Dr. Cobbold, of London 

 (" On Tapeworms," London, 1866), who found a spe- 

 cimen in the Museum of the Middlesex Hospital : 



"When complete, it must have measured 8 feet 

 in length. It is characterized by the presence of a 

 ridge, extending through the entire length of the 

 body, imparting to most of the segments a pentagonal 

 figure, when viewed from the front. The individual 

 segments are much smaller than those of the full- 

 grown tapeworms ; and they are further characterized, 

 collectively, by the presence of uniserially disposed, 

 reproductive papillae, extending along the left margin 

 throughout the entire chain. The papillae are very 

 prominent, being placed at the centre of each joint.
