mach, is about half its length, and internally furnished wit 

 lists. The stomach is capacious, widest in the first half, an 

 tapers sharply downwards, then turns off, almost at a rigl 

 angle, and lessens rapidly towards the gut. 



The stomach is furnished with numerous (in the midd 

 22 — 24), high and narrow lists. The pylorus gland empti« 

 ltself into the stomach, behind the middle of a wart, surrounde 

 by a circular shaped fold. The gut goes first perpendicular 

 upwards, then makes a level turn, and again rises perpendicv 

 larly, this latter perpendicular part is unusually long (fig. 1? 

 Anus with 2 flat, downward bent, striped lips (fig* 16). ] 

 the gut, in the beginning is found a strongly defined rom 

 list, formed by a coalescence of 2 — 3 of the lists of the st 

 mach, this list disappears in the compressed rectum. The mc 

 characteristic of the intestinal canal, is the stomach bent 

 almost a right angle, the unusually high pependicularly risii 

 part of the gut and anus with their 2 striped and down be 

 lips (fig. 3). 



On the right side, a large, and very characteristicai 

 formed Gonad ; it consisfcs of 5 branches flowing down togetb 

 (fig. 17). In the section (fig. 19) is seen a split-formed can 

 on the upper side of which are found numerous egg cells; o\ 

 this layer of eggs, and also under the canal are found numerc 

 seed sacks, whose excretory ducts run up on the upper si 

 of the gland.

 (Fig. 20—25). 



Only 2 specimens of this new species are to be fon i 

 amongst the material that I have examined. These 2 spe- 

 mens have a somewhat different exterior form. Both É 

 strongly arched, but whilst the larger specimen is firrf 

 attached with a very broad basis (fig. 20) the testa be ? 

 discoidally spread upon the shell fragment upon which e 

 animal is sitting; the other and smaller specimen is with t 

 extented basis (fig. 121); this latter, presumably, has bu
