salivary glands lie immediately behind it, covering the anterior 

 part of the alimentary canal, while in most Helicid^:, they are 

 on long peduncles and situated at the lower anterior base of the 

 stomach. The oral parts and the salivary glands are pinkish grey. 

 The intestines make only a slight bent and the rectum is accom- 

 panied by a very narrow albuminous gland, along which also the 

 duct leading from the kidney appears to lay. 



The retractor muscle of the body is divided in two very broad and 

 strong parts ; they are attached to the anterior end of the food, 

 below the mouth, and divide posteriorly again into several thin 

 branches. The retractor muscles, supporting the buccal parts, are 

 shorter and also bipartite. The nervous glanglion ring lies imme- 

 diately behind the mouth and is covered up by the anterior part of 

 the salivary glands ; it is very thin and gives only a few very thin 

 branches to the lips, the pedicles and to the generative organs. 

 The small extent of the nervous system is very striking, as com- 

 pared with the same organs in the Helicid^e and ZoNiTmas. 



The generative organs fill the anterior part of the body nearly 

 entirely. The uterus is comparatively thin, of grey colour ; the al- 

 buminous gland (alg), attached to it, very large, nearly as long a,s the 

 uterus, and more than double its thickness. The receptaculum semi- 

 nis (rs) is an oval pedunculated gland, laying either along the 

 uterus, or obliquely across the body, a short distance below the 

 hermaphrodite opening, enveloped in soft tissue. It is provided 

 with a long appendage, attached along the uterus, and equal in 

 length to it. This appendage (ad) contains an orange coloured, 

 tough flagellum, filled with a whitish substance, and possibly 

 represents, the arrow (or amatorial) sac. 



I have not observed the presence of spermatozoa in the so-called 

 'receptaculum seminis;' it was filled with flattened transparent 

 bodies and some colouring matter. The vas deferens branehes off 

 about half way from the uterus, makes a few twists, attaches itself 

 to the tissue just below the hermaphrodite opening, and then shortly 

 after becomes thickened, being at this place fixed with a small and 

 thin retractile muscle. The penis makes three distinct twists, or 

 almost coils ; it is very long and the terminal half is more thickened 

 than the other ; it ends with a thin flagellum.
