" 1'liis very interesting species differs widely in i'orm from the 

 only previously described sinistrorse Diplomi)iatina inhabiting 

 India, D. Jiuttoni, Pfr., more widely than it does from some of the 

 reversed forms met with in the Oceanic region. It shews a con- 

 siderable resemblance in form to D. murtensi, H, Ad., of unknown 

 locality, figured in the Proc. Zool. Soc. for 1866, but which is said 

 by its (lescriber to belong to the section JJiancta of Martens, 

 characterised by a constriction at the back of the penultimate 

 whorl. In D. gUihosa, as in most Indian Diplommatinse, there is 

 :i slight tendency to constriction in front of the penultimate 

 whorl, to which an internal rib appears to correspond, but w])ich 

 is covered and concealed to a great extent by the parietal callus of 

 the peristome." {Blanford.)
