6 0. F. von MollendorfE — On a collection of Japanese Clausilise. [No. 1, 



knew any species of Bottger's AcropTiaedusa (1. c. p. 64). This group, com- 

 prising two Javanese Clausilise, G. Junghuhni, Phil., and cornea^ Phil., is 

 perhaps the only one to which these novelties could be referred. On 

 the other hand, there are relations to the first subgroup (" Formenkreis") 

 of Heyniphaedusa. Unfortunately, Mr. Hungerford collected only a few 

 specimens of each, and I have been unable to study the clausilium of either 

 species. The decision whether they belong to HemipTiaedusa as a special 

 subgroup or ought to form a new group by themselves has to be reserved 

 until more material will allow the breaking up of some specimens.

Testa ventricosulo-fusiformis solida cornea suhtiliter striatida sericina ; 

 anfr. 10 — 10| convexiusculi sutura distincta, ultimus subdistortus, Tiaud 

 magis striatus ; apertura suhohliqiia^ rotundato-piriformis ; peristoma con-

Hab. Two specimens of the typical form from Chinsinji, and one 

 specimen of the smaller variety from Yumagaaishi. 



The palatal plaits might be compared to those in the group Stereophae- 

 dusa, from which our species is otherwise widely different. The lower 

 parietal lamella refers Gl. sericina to Hemiphaedusa.

This novelty likewise does not seem to fit into any of Dr. Bottger's 

 subdivisions of Fhaedusa. The lower parietal lamella reminds one of that
