Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. W. Rasmussen 1951 | A Ceramaster whose compact median marginals are as long as they are broad, the height being distinctly less. The ultimate superomarginal is smaller than the median superomarginal; it may correspond to more than two one inferomarginal. The two most distal superomarginals from each side of the arm have met in mid-line of the arm. The outer surface of the marginals have shallow, closely placed pits which have borne steae. The central part of the surface is slightly elevated and bears scattered somewhat deeper, circular pits. This specially ornamented central area is strongly reduced on the median superomarginals and is quite absent on the inferomarginals. |
