This species, which we, as well as Gredler, have formerly mistaken 

 for C. FUippina, Heude, is distinguishable from its allies in being very 

 strongly striated, in fact " costulato-striatus," and in possessing the 

 trace of a lunella, the minute central palatal plaits forming a faint 

 callosity. 



Dr. Boettger has in his possession a specimen said to have been 

 found at Tongsan in the district of Seizo. 



As Gredler has already pointed out, the nearest ally to our species is 

 C. adaucta, Gredler.^ The latter is, however, larger and more slender ; 

 the whorls, which attain to as many as 14, are much flatter and are 

 evenly and minutely striated, not "costulato-striatus" (the striation on 

 the neck is three times finer than in C. Tetsui) ; besides its colour is of 

 a darker brown shade. In the oral folds the most notable difference 

 is that the upper plica palatalis in C. adaucta is more divergent 

 in front, descending in an arched curve, whilst in C. Tetmi it runs 

 nearly parallel to the plica principalis. C. Tetsui is viviparous.
