convolutions. The penis, (figs. 7 and 8, /,) when retracted, 

 has an irregular convoluted form in consequence of being 

 folded upon itself. The ovary (fig. 7, c,) is a yellowish colored 

 organ, very slightly lobulated, has a conical shape, its base 

 resting on the oviduct. Tiiis last consists of two portions; 

 the first, commencing at the ovary, is united with the vas 

 deferens, and forms numerous folds upon itself, resembling 

 an intestine ; it terminates in the second portion 7v, which has 

 a very small diameter, and without any convolutions. At 

 fig. 7, h, and fig. 8, a, is a rounded vesicle, which is 

 supposed to resemble in function the spermatheca of insects, 

 and which is united with the oviduct at its termination, by a 

 long slender duct (i and h.) At the termination of this duct is 

 the small coecum (fig. 7, z,) of which there is no analogue in 

 the Limaces. Both the male and female organs terminate in a 

 common sinus (fig. 7, /, and 8, h.) This sinus is provided 

 with a yellowish glandular organ which nearly surrounds it 

 externally. The external orifice of the organs of generation 

 has already been described.
