the hooka are longer on each succeeding segment, longesl on 9th; book 

 on LOth very small, triangular, erected, blunl a1 tip; lateral spines on hIi 

 mid 9th segments Qat, sharp, short ; a little Longer on 9th, half again as long 

 as LOth; anal appendages twice a- long as Kith segment, pyramidal, sharp; 

 dorsal median hardly as long as the inferiors; tips Blightly benl up; dor-
