Thanks for the detailed information, Wayne. I believe the depth of the
dredged sand is 100-140 feet. Is that right?
I am looking over some of the micros from my second visit to JU Lloyd. Among
others, I found four Cyclostrema cancellatum, a second Cirsotrema dalli (I
want my dalli!), Vexillum cubanum, 2 more worn Crassispira adamsi (deemed
rare), and several more Viridrillia cervina.
I will be adding to my list of new-to-me species fairly soon. (I sent of
list of 38 to Conch-l some months ago).
Save some of the drift for us out-of-staters, folks!
