shell was quite as in the typical species, of a length of 1.6 — l-8 om , by a breadth of 

 1-2— l om . 



The bulbus pharyngeus had a length of 3 - 35 — 3"5 mm , with a backward some- 

 what projecting radula-sheath. The radula was brownish yellow. In the radula were found 

 13, 15, and 16 series of tooth-plates, in the sheath 10 and 9 such, and thus the total 

 numbers of series were 23, 24, and 25. The length of the plates (measured in a straight 

 line) was 0'7 mm , the colour was light yellow; the number of the denticles was nearly 100. 

 — The salivary glands quite as in the typical species. 



The length of the masticatory stomach was 9 — ll - 5 mm by a breadth of 5.5 

 — 6.5 mm . The stomach plates were of the common form, also violet on the outside, or 

 more brownish with a whitish middle part, and with the common two small holes; now 

 and then calcified globules were also found here on the outside of the stomach plates. — 

 In the cavity of the stomach shells and shell-pieces of a bivalve were found in an inde- 

 terminable animal mass mingled with grains of sand. 



The bag of the penis had a length of from 2 - 5 up to almost 3 mm . The prostata 

 formed, as in the typical form, a large ball of windings, mostly of a diameter ofO'OlS" 1111 ; 

 the small globular gland as above. The hammershaped glans had (in all three specimens) 

 longer legs than that of the typical species, and its sheath was longer and bifurcate. 



This latter circumstance seems rather different from that of the typical form , but 

 on the other hand it is scarcely sufficient to justify an establishing of a new species. 

 The number of species already etablished on the variations of the shell, is sufficiently 

 large ')•
