 See Plates 11a. 13 and 15. 

 Fig-. 1. An unusually perfect pygidium of about average size, showing the general convexity, the irregu- 

 larly scattered nodes, and some of the marginal spines. The second spine on the right margin 

 of the shield was apparently broken off ami healed during the life of the animal. 

 Fig. la. A transverse section in outline near the anterior margin, to show the convexity of the axis and 

 pleurae, and the upward direction of the spines. 



Corniferous limestone. City Hall quarry, Kingston, Ulster county. 

 Fig. -. A fragment of the pygidium of a very large individual. 



Corniferous limestone. Schoharie, Schoharie county. 

 Fig. 3. A fragment of a smaller pygidium, showing the length and curvature of the marginal spines. 



Corniferous limestone. Schoharie, Schoharie county. 

 Fig. 4. A fragment, showing the terminal portion of the pygidium. This figure is from the original of 

 Mr. Conrad's Asaphusf acantholeurus. The drawing does not make the base of the central 

 spine sufficiently large. 

 Fig. 5. A side view of a gutta-percha impression made from the counterpart of the foregoing specimen, 

 showing the length of the spines on the posterior border. The central spine is normally bifid, 

 but this character is not perfectly retained in the impression. 

 Fig. 6. The same viewed from the front.
