In preserved specimens the "frontal tentacles" of Schmarda (Mund- 

 l^olster, Ehlers) are hardly ^isible. 



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 setae in the lower part of each ramus. 



Ehlers' remarks upon this genus and species seem to be accurate in 

 every respect. 



Fam. ARICIID^. 



ANTHOSTOMA Schmarda.

 feet and setae in text). 



The collection contained but one specimen of this species, and that 

 very badly injured, but sufldcient for identification.
