'' This Leptopoma may be distinguished from any of the varieties 

 of L. vitreum by its angular periphery, dark apex, more convex 

 whorls, deeper suture, double peristome and parietal callus, as well 

 as bv the reflexion of the columellar lip over the perforation, and 

 of the narrow lip above it. It is deficient also in the angular 

 projection observable on the lower part of the same lip in that 

 species." (Benson.)

" In form it most nearly approaches L. vitreum, Qu., but has a 

 more acuminate spire. Its sculpture has greater resemblance to 

 that of the more globose and depressed Bornean species, L. seri- 

 catum, Pfr. The smaller specimens have a more conical and 

 trochiform appearance than the larger ones." (Benson.)
