Nerve collar. — This is placed '2 inin. from the head suvrounding 

 the oesophagus. 



Genital organs. — Male : The irregularly convoluted testes reach 

 within 2-5 mm. of the head extremity. There is a dilated 

 seminal vesicle. The ejaculatory duct traverses the long cement 

 gland to terminate in the cloaca. 



Female : The vagina pursues a vertical course in the long 

 axis of the body. It is -52 mm. long. Into its cephalic end the 

 two strongly muscular ovejectors open, each connected with the 

 corresponding uterus. The two uteri lie side by side, lying 

 mainly in the axis of the body. The irregularly convoluted ovary 

 reaches within 2*75 mm. of the head end.

Bursa. — The bursa is distinctly divided into three lobes. 

 The dorsal lobe is much longer than the lateral. The bursa 

 is smaller than that of M. vieni^yhisia, but corresponds to it in 

 shape and in the arrangement of the rays. It is "5 mm. in length 

 and '45 mm. in breadth. The ventral and lateral rays are similar 

 to the coi'responding rays in the type-species. The fourth division 

 of the lateral ray is shorter and knob-like. The externo-dorsal 

 ray does not reach the edge of the bursa. It gives off near its 

 origin a small ray, which is characteristic of the genus. It is 

 shorter than that in M. inemjyhisia, being "05 mm. in length, 

 and its end is pointed.
