FIG. 14. E. blumi is marked to indicate the segments I. to VI. (Richters), and the 

 lateral processes a, b, c, and d. Those four processes are seise, but e is lacking in this 

 species. At the base of a is the " auricle." Segments V. and VI. having completely 

 coalesced, the single segment resulting is referred to as V. + VI. The figure shows 

 also a little sharp spine on the first leg, a blunt palp at the base of the fourth leg, 

 the "fringe" of sharp teeth, and the " barbs " of the outer and inner claws.
