stauce to be deposited within the incubatory cavity in the form of 

 ova. In this case, the whole organ can be very distinctly traced 

 throngh the pellucid shell (see Pl. II, fig. 2); and moreover, we 

 can state that the ovary is emptied through a short and rather 

 wide oviduct, entering, it would seem, the basal part of the eleven th 

 pair of legs, this duct being likewise filled up with the opaque green 

 substance spoken of above. On examining this pair of legs 

 closer, I have failed however to detect with certainity the opening 

 through which the ova are expelled. The egg-cells would seem 

 to develop in the walls of the ovaries, being at first very small 

 and pellucid so as only with great difficulty to admit of being 

 examined, and, apparently owing to this circumstance, the whole 

 organ can in most cases be traced but very faintly through the 

 shell (see Pl. VIII, fig. 4). 



As to the male genital organs, I have nothing at present to 

 record, having unfortunately been prevented from examining full- 

 grown male specimens.
