tor the most part wider outwards than inwards. These compart- 

 ments are filled with laminae, which, in the largest specimen that 

 I examined, were, witli the exception of the hindermost, com- 

 posed of eggs in different stages of development, so arranged 

 that the mopt developed were placed outermost (32). The 

 innermost part of every lamina is formed of small cells 

 probably of the same character as those from which the eggs 

 had been developed (33). Such cells were also fonnd between 

 the eggs. In two smaller specimens on the contrary the ex- 

 teriör portions of these laminse consisted of a granular sub- 

 stance, also cellulär, but of an entirely different character 

 from the cells just mentioned (34). In these specimens only 

 the inner parts are occupied by eggs and egg-cells (35), biit 

 in them also the arrangement is such that the largest eggs 

 are outermost. I have not been able to discover either in 

 what relation the granular mäss stånds to the eggs, or by 

 what means the eggs, when mature, are discharged from the 

 ovary. It would be natural to suppose that they come out 

 into the stomach by breaking through the walls of the ovary, 

 and are aftorwards discharged through the anus, but this would 

 be inconsistent with their appearing in the bag (6 x) behind 

 the rectum. This bag I found, at least in the larger speci- 

 mens, filled with a number of irregular bodies exactly resem- 

 bling the more mature eggs in the ovaries, but with their 

 contents less transparent and without any distinct nucleus. I 

 cannot conjecture what else these can be than eggs, though I 

 cannot account for their presence in the bag. In this organ 

 are also three singular bodies, oue above and two below, which 

 in the smaller specimens looked like mere elevations on the 

 wall of the muscular coat, but in the largest specimen diflPer 

 considerably,- inasmuch as that, throughout the greater part 

 of their length, they are free, and the upper one is longitudi- 

 nally divided by a furrow (6 y). The compartments of the 

 ovary nearest to this bag contain no eggs, but are filled with 

 laminjE of a yellow shiniug substance, the nature of which I 

 am not at present able to explain. No external limit is vi- 

 sible between this part and the rest of the ovary, and the 

 yellow shining laminaj begin almost immediately where the 

 formation of the eggs ceases. Possibly this organ may commu- 

 uicate with the two large lateral glands (29 a). These two glands, 

 of which I did not succeed in making entirely uninjurod pre-
