The armed area occupies the entire surface of these joints, excejtt a narrow lateral free space. The arrangement of the spines ou these joints, excejit the last, is uniform, with iterhaps a slight increase in the size of the spines from the second to the eleventh joint. 'I'ho arnuituro of these joints and of the anterior half of the twelfth consists of a rather ])romiaent and posteriorly directed row on the anterior margin of each joint, I'ollowed by numerous suuiUer prickles, which decrease in size and abundance toward the posterior margin of the joint. The posterior half of the terminal joint is armed with very much larger and slightly curved jtrickles or spines, which point posteriorly on o!ie side and anteriorly on the other(see fig. 43, h).
