Yes, #1 is Busycon sinistrum.  B. aspinosa is a synonym.
No, #2 & 3 are not Fasciolaria tulipa; they are Fasciolaria hunteria or
lilium (whichever is acceptable these days).
I don't believe the citrina form of Oliva sayana has any pattern; it's just
golden-yellow in color.
#4 & 5 appear to be 2 forms of Busycon spiratum.

Hope this helps.

Subject: Different forms? Help!


Hello everyone, and Happy Mothers Day to all Mothers on the "L".

My collection seems to be growing in species these days, sometimes without
adding specimens. I'm a bit confused about a couple shells I have, as to if
they are a different form, or what I have. Please view them in the "Help"
album at:

#1: I always thought this was a rounded form of Busycon sinistrum, but is it
really B.  Aspinosum?

#2 & #3: I know #3 is Fasciolaria tulipa, but is #2? (both live collected in
same shallow area)

#4 & #5: I know #5 is Busycon spiratum, and I'm pretty sure #4 is not the
same. (both live collected in same shallow area)

#6: I thought this was just another Oliva sayana, but I've been lead to
believe this is the "citrina" form. I was told that what mattered for this
form was the background color, not the pattern. I always thought the whole
shell was pretty much yellow or golden in color for it to be the citrina
form.

Thank you very much to all who reply!
