drawings show the inner surface and the outer surface of the 

 intestine. The body of the worm is rather flat though at the 

 same time fairly thick, and is curved in a sickle-like fashion. 

 The length of the larger of the two individuals is about 1^ inches, 

 and the greatest breadth does not exceed 5 mm. There is not a 

 very marked difference in diameter at the neck end of the body, 

 and the worm thus presents a very solid and strong appearance, 

 which is correlated with the very firm way in which it is im- 

 bedded in the gut. The narrowness of the segments and the 

 lack of overlap of successive segments contributes further to the 

 stout appearance of the worm.

The last two or three segments of the body are rather narrower 

 from side to side and are curved, thus tending to encircle each 

 other successively. This state of affairs is shown in the drawings 

 referred to. Anteriorly the strobila is seen to perforate the wall 

 of the intestine, which forms a fold round it, like a collar not 

 fitting very closely. The strobila at this point disappears from 

 view when the intestine is examined from its internal surface.
