"This singular species is peculiar to the island of Koro, where it 

 is very abundant in the central valleys. They were found lurking 

 under loose stones, rotten wood, and among decayed leaves. About 

 one specimen in a hundred exhibits slight traces of a brownish horn- 

 colored epidermis, disposed in irregular longitudinal stripes. They 

 are often much more attenuated than the dimensions [53, 18 mill.] 

 given above. Very old specimens are frequently denticulated on the 

 peristome " (Garrett). 



The figures sufficiently show the variations mentioned by Garrett. 

 The original figure was from a scarcely mature shell which retained 

 traces of the cuticle. Type in coll. Acad. Nat. Sciences. 



Dr. Schmeltz considers koroensis and kantavaensis specifically 

 identical. In the large series I have seen of shells collected by Gar- 

 rett, there are none agreeing with Crosse's figures and description in 

 size and pattern of cuticle, but it is not unlikely that koroensis might 

 well be subordinated to kantavuensis as a variety. Further investi- 

 gation of the Kandavu fauna is necessary, to confirm the locality of 

 the latter species, and its range of variation.
