Three new unnamed species that are currently in manuscript, Pygaster sp. and Heterosalenia sp. Type 1 and Heterosalenia sp. Type 2 are also described.
Two previously listed Texas echinoids are being removed from the list of Texas echinoids because the specimen Clypeaster sp., Plate 18 was actually from Houston County, Georgia and not from Houston, Texas and Craneipedina williamsonensis, Plate 39 was miscataloged and was from Europe.
Tetragramma adami, Thompson 2016 is placed in another genus and renamed as Strictotiara adami (Thompson 2016). Pseudocidaris ridiculum, Thompson 2016 is placed in another Genus and renamed as Heterosalenia ridiculum (Thompson 2016).
In my study of echinoids, I met Trevor Clarke, a passionate young man of Virginia, that had found some echinoids in Virginia. One of the echinoids he found is also recognized in this book and named Habrocidaris clarki sp. nov.
