regarding daughter bladders. These are deciduous scolices, but they 

 are not daugliter bladders. It is interesting to note that we have 

 here a condition suggestive of what must have been the origin of 

 daughter bladders, namely, a deciduous scolex, but it is so recent 

 a development here that the cyst has not yet developed a reparative 

 process at the site where the scolex separates. This species is appar- 

 ently intermediate between M. muUiceps and M. serialis in this and 

 other respects. It presents an interesting study from a physiological 

 standpoint in that it is capable of development in the central nervous 

 sy stein and also in the connective tissues and on serous surfaces, 

 thus combining the sites of the other species, and causes the forma- 

 tion of an adventitious capsule, as M. serialis does and 31. niulticeps
