Julus Virginiensis of Drury, is also rather com- 

 mon, it appears to be synonymous with /. tridentata 

 of authors. I have found specimens double the usu- 

 al size, in the southern States. It seems also to va- 

 ry in having only the second joint of the feet mucron- 

 ate, and in being destitute of the robust ventral spines 

 between the feet. 



%. P. *granulatus. Segments granulated, granules 

 subequal, arranged in four series.
