Gould did not figure this, but the figure in the Couchologia Indica accurately 

 represents his species, judging from a cotype in Lea's collection, sent him by Dr. 

 Gould. A number of these Pseudodons are very close, anil it is quite probable that 

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