specimen, not the actual specimen itself.  Could this explain the   
reversal?>

No. Casts are duplicates of the original. This reversal is a photographic   
effect, for whatever reason. You can see the cover's reversed image at:
http://www.amazon.com/covers/0/37/540/119/0375401199.l.gif

And compare that to an accurately portrayed image of the same specimen   
at:

the bottom of the page.)

PS: I bought the book anyway. It's very good so far.
