Photographs of Cryptolithus tessellatus Green, made by C. E. Beecher.
Fig. 1. Specimen 231. A nearly complete individual, cleaned from the ventral side and showing obscurely the hypostoma and fragments of numerous appendages. Note the lines of appendifers along the sides of the axial lobe. × 11.
Fig. 2. Specimen 232. Although this is not very well preserved, it shows more of the cephalic appendages than any other. Even so, only just enough is shown to indicate that they were similar to those on the thorax. × 12.
Fig. 3. Specimen 235. Dorsal side of the appendages of the thorax and pygidium. See [pl. 7, fig. 2] for the ventral view. On [pl. 9, fig. 2] (left side) is a drawing taken from the same specimen. × 11.
