Kurt,
 
Great start and I appreciate the information on Hastula.  As for the
taxonomy, I find this family is as confusing as the turrids will be if
anyone ever really looks into them.  I was very conformable calling all
in the family terebra until I read the "Living Terebras of the World"
and found they (authors Bratcher & Cernoohorsky) break the family into
the genera: Terebra, Duplicaria, Hastula (with subgenus Impages), and
Terenolla.  They also list 41 or so previous genus and subgenus name
applied to this family.  I still have all of mine labeled as Terebra
with the actual genus name (if other than Terebra) in parenthesis, i.e.
Terebra (Hastula) salleana.  I know, I know, not the accepted or correct
way, but if anyone complains I just kick them out of my
shell/computer/herp room.  My excuse for the incorrect labels has always
been that I was waiting for the name game to settle out.  So my question
to you, is the taxonomy given in the Terebra book current and accepted?
And second, can you send a scanned picture of your Terebra imitatrix?  I
would like to slip it into my book.

By the way, I think the Terebra (Hastula) lanceata and the Terebra
(Hastula) strigilata are two of the best looking terebras going when it
comes to color and pattern.  When it comes to shape, my vote is for the
Terebra triseriata for its almost unreal thin shape and fine sculpture
and finally, of the large guys, Terebra commaculata seems to combine the
nice, thin shape with a good strong pattern.
