From the figures referred to above, there would scarcely (in 

 the last two named) arise a suspicion of identity. The speci- 

 mens themselves have passed under my examination, and from 

 an extensive suite of the varieties, I had no difficulty in at once 

 recognising them as the extremes of this species.

The reversed specimens of this species undergo changes 

 which have led to their being considered distinct species. I 

 have, however, been unable to seize upon any permanent cha- 

 racters in any one of the varieties where a specific line can be 

 safely drawn.
