Weber, the ovaries lie free in the body cavity ; they are 

 not attached by a fimicle. In this specimen they are lying on 

 the level of the tenth pair of legs, but considering that they 

 are free from the wall of the body cavity it seems probable that 

 their position in the body is variable, just as it is in P. Sedgwicki. 

 The free situation also probably is the cause that in the examined 

 specimen the ovaries are strongly convohited and that their blind 

 tip is situated nearer to the anal extremity of the animal than 

 their distal end. These distal extremities of both ovaries are 

 united into a common atrium, and the two oviducts, which are con- 

 tinued in the strongly coiled uter'i, proceed from this atrium. Whereas 

 however the right oviduct immediately after its origin from the 

 atrium is directed to the hinder extremity of the body, the left 

 one is bent forward, the origin of the left uterus being thus 

 situated in front of the atrium. All this, however, is of course 

 of little importance and probably varies with the grade of develop- 

 ment of the uterine embryos. The uteri are united into a short 

 vagina, which opens to the exterior between the last, rudimentary 

 pair of legs. The walls of the ovaries (fig. 1) are thick and con- 

 sist of a fibrous layer, at the inner and outer side covered by 

 a layer of more or less epithelially arranged cells, the nuclei 

 of which show the characteristic pear-shape, which Sheldon ') de- 

 scribos and figures in the case of P. capcnsis. 



Almost all the eggs are „exogenous". Each ripo ovarian Ggg lies 

 at the extremity of a long cellular stalk, rising from the wall 

 of the ovary (fig. 2). In appearance these stalks agrce with those 

 of P. capoms and Balfouri., after the description given by Shel- 

 don. However I am not sure if there is a follicle surrounding 

 the whole Ggg'^ at all evonts it does not contain nuclei. The 

 stalks are slender, somewhat enlarged towards the tip; in their 

 narrow(!st part they are often compressed ribbon-like and but one 

 cell thick and two or three cells broad. Each egg-stalk is con- 

 tinued at its root by a string of cells, which perforatcs the fibrous
