Two specimens of cranidium are shown one near upper margin and one on left side between the two 

 pygidia. The pygidium at the lower left side may be referred to this species. The pygidium above 

 on the left side is that of Dolichometopus deois Walcott. [See plate 22.] The hypostoma near 

 the top and the large pygidium on the right are referred by Lorenz on the label accompanying the 

 specimen to Anomocare sp.
