In preserved specimens the ‘“‘frontal tentacles” of Schmarda (Mund- 
polster, Ehlers) are hardly visible. 
The anterior feet with all their appendages are shorter and wider than 
those further back (Fig. 90). After the first few segments there may be 
from one to three stout bi-dentate sete in the lower part of each ramus. 
Ehlers’ remarks upon this genus and species seem to be accurate in 
every respect. 
Fam. ARICIID.

very badly injured, but sufficient for identification.
