The ordinary segments give an average breadth of ^ 

 of an inch, those at the caudal end stretching to as 

 much as f of an inch in length. Their greatest thick- 

 ness does not exceed the ^ of an inch. The eggs 

 resemble those of other tapeworms, and offer a diam- 

 eter of about -T^ of an inch." 



L)r. Cobbold considers this worm as a new variety, 

 differing from T. solium and T. mediocanellata, in the 

 size of the segments and the uniform disposition of 

 the papillae ; from Weinland's T. flavopunctata, in its 

 large size ; and from Kiichenmeister's T. capiensis, in 

 having the genital pores unilaterally situated. In his 

 description, I should judge the head was wanting, as 

 was Kiichenmeister's ; for at the beginning he says, 

 " When complete, it must have measured," &c. More- 

 over, he does not describe the head at all. With the 

 exception of the position of the reproductive papillae, 

 it agrees pretty nearly with Kiichenmeister's descrip- 

 tion of the T. capiensis. Would that exception be 

 sufficient to base a new genus upon ] I would sug- 

 gest whether it might not be identical with Kiichen- 

 meister's T. capiensis, especially if, as Dr. Cobbold 

 remarks, it may come from mutton ? Kiichenmeister's 

 specimen was supposed to have come indirectly from 

 the cattle of the Caffres ; and, of these, sheep form a 

 large proportion. It certainly is an interesting ques- 

 tion. 



Of the Bothriocephali, there are now known to be 

 two species : the B. latus (already described), and the 

 B. cordatus (PL III. fig. 5), a new species, recently 

 described by Leuckart, who received about twenty
