L. ~beccarii and L. dohertyi are allied, but both have a 

 much more strongly developed color-pattern, and the spire 

 of the former is longer and less obtuse. L. liabrawalensis 

 Jouss., seems also from the description to be related. L. don- 

 aldsoni has very convex, beautifully granose-decussate whorls, 

 a moderately open umbilicus and very faint coloration. L. 

 keniana is similar to donaldsoni in coloration and the obtuse 

 summit, but it is imperforate.

 an impressed, irregularly crenate suture, the last whorl ob- 

 soletely angular at the aperture. Aperture oval, lip thin, 

 acute, columellar margin narrowly involute. Length 35-47,
