T^NIA ACANTHOTEIAS. 



length of the broacl wrinkled body of the worm is estimated by 

 Weinland at about 10 mm. The bladder is as large as in Cysticercus 

 cellidosce.

The size of the hooks, according to my measurements, was some- 

 what larger than according to Weinland. According to me they 

 measured 0196, 0'14, 0'07 mm., while according to Weinland they were 

 only 0-153, 0114, 063 mm. The length of the roots I estimated at 

 01, 0'07, and 0'035 mm., and the height from the point of the anterior 

 process upwards at 01, 0'08, and 0-045 mm. The posterior processes 

 were relatively longer than in Taenia solium. The whole form is, as 

 we have seen, somewhat slender, and this applies to the processes 

 as well as to the hooks. The brown coloration of the root-processes 

 is striking, and at one position in the large hooks becomes developed 

 into a distinct black line.
