and adlierent to tlicir walls. I tloubt, thorofore, whether these 

 spaces are the remains of the uterus, or whether they are not 

 rather cavities which have arisen in the medullary region perhaps 

 by stretching of the walls of the body and consequent laceration. 

 The eggs, in fact, lie scattered through the })!vronchyma, some- 

 times singly and more often in masses of various si/os, as is 

 shown in the figure referred to. The eggs are not limited 

 to the medullary region. It is clearly to be observed that 

 they extend into the cortex (text-figs. " 1 20, 121) a good way

towards the extei'nal layer of the body-wall. They stop short, 

 however, some way below it. It is quite certain that whether 

 or no there may be remains of the uterus, some of the eggs lie 

 scattered within the parenchyma. In the cortical parenchyma 

 they are to be seen between the muscle-bundles and closely packed 

 in masses. The appciirance is, indeed, not at all unlike that 

 which I have recently described in the tapeworm Ait02)lota>,ma

 not so conspicuous; for in the latter worm there are uterine
