What are the identifying characteristics of Henrya goldmani vs. Henrya henryi ? I've looked at the Bartsch and specimen images on Jaxshells, the one image in Texas Seashells but can't find a description that separates the two. (The images on GBIF of H. henryi are ones I took, so I don't want to breathe my own exhaust.) The two figured here are from Bunche Beach, Lee County, FL. The protoconchs are similar although the one on the left is slightly more angular. The specimen on the right is narrower but I'm not sure if that's meaningful or just species variation. I'm tempted to say that the one on the left is H. goldmani and the right is H. henri but certainly am not confident. Would appreciate any way to determine if these are the same or different species. Thanks.
