but in considering the function of these intricate organs it should 

 not be lost sight of. 



Fig. 8, here inserted, will, from the large scale on which it is 

 drawn, materially assist the general description of the generative 

 organs which we have given. It will also help to convey a 

 correct idea of the formation of the " intromittent organ" (a), 

 when exserted.

The intromittent organ, or generative appendage. — In our ex- 

 amination of illustrations of the fluke we have not met with 

 any correct representation of this organ ; we can, however, 

 speak in favour of the one here given ( jig. 8). The illustration, 

 together with most of the others which we have employed, is 

 original. In each we have endeavoured to represent special 

 portions of the organization of this interesting and somewhat 

 complicated entozoon, rather than to adopt the not unusual plan 

 of mixing all the organs up together in one illustration.
