 ones highly polished. From the 7"' segment a small dorsal spine, which 

 at first consists of a minute, ti-ansverse, spiny crista, about the 1 1"' seg- 

 ment constricted to a simple spine proti'uding from the distal ])art of 

 the segment. Distal cirrals L = '/2 — "/s ^ ^^'- The height of the spine

 and a little smaller than the preceding ones. Terminal claw curved
