ERROR on page 92 and Plate 86:
Wrong photo (the photo is of a Palhemiaster calvini from the Buda Limestone, Travis County, Austin.
UPDATE:
(See corrected photos below of another specimen.)
The difference in a Hemiaster and a Palhemiaster is that the Palhemiaster has only a partial peripetalous fasciole.
Also please note the arrangement of the paired ambs that create a perfect "X" thru the center of the test. The amb on the top left is in line with the interamb on the bottom right, and the same with amb on the top right in line with the interamb on the bottom left.

UPDATE:
Series: Unknown Group: Unknown Formation: Unknown
According to Louis Zachos, there are "no lunulate sand dollars before the Miocene". Also according to Dr. David Rohr, there are no marine formations of the correct age close to this locality. After speaking to Mr. Costabile, I personally visited this locality and hunted unsuccessfully for other such echinoids in the Pen Formation and later found out that I needed to hunt much higher in the formation. Maybe a later hunt will provide an answer. Until then, ther Formation will remain Unknown.

Temnholectypus limitis in Remarks by Book Author:
UPDATE:
This species is clearly a Temnholectypus instead of Coenholectypus because the periproct is separated by 3 or more interamb plates from the peristome.

The specimen in the UT NPL collection is not of a Washitaster inflatus when compared to Cragin's photos. The specimen UT 17249 looks like Washitaster bravoensis.
