COLLINGE : A XEW SPECIES OF LIMAX, FROM IRELAND. 



Anatomy of Generative System. 



The \estibule is indistinct, being formed partly by the 

 terminal portion of the penis and free o\iduct. The penis 

 commences as a narrow tube dilating into a bulbous portion at 

 about the first third of its length ; from here it is a wide, thick, 

 muscular walled organ, folded upon itself so as to form a spiral.

The vas deferens is almost as long as the penis, of which it is a 

 direct continuation ; at the junction of the two organs a large 

 retractor muscle is attached. The free ovdduct is much shorter 

 than the penis, and consists of a narrow tube, which, previous to 

 its joining with the oviduct, makes a sharp loop (fig. i), which 

 was characteristic of the three specimens dissected. The oviducal 

 portion (fig. i, ov.) of the common duct is richly convoluted, 

 becoming almost filiform at about its middle third ; the prostatic 

 portion (fig. i, pr.) is a long, narrow tube, externally slightly 

 pigmented. The receptacular duct, unlike that in L. maximiis,
