The megascleres exhibit the basal spination more com- 

 monly than do those of the typical variety. Practically all the 

 auxiliary and special dermaf styli are thus provided, as well 

 as a considerable proportion of the principal st\li. The 

 acanthost}les are usually more or less dehcient in spines over 

 part of their proximal moiety.
