^ Gould did not figure this, but the figure in the Conchologia Indica accurately 

 represents his species, judging from a cotype in Lea's collectiou, K«ent him by Dr. 

 Gould. A uumber of these Pseudodons are very close, and it is quite probable that 

 some of them must be united when sufficient material is studied.
