THE MYRIAPODA OF NORTH AMERICA. 149 



The first under the name of Jul us virginiensia is placed as a note 

 along with Poiyd. serratus. Concerning this species Say says: 



I have found specimens double the usual size in the Southern States. It seems 

 also to vary in only having the second joint of the feet mucronate, and in l>ein<£ 

 destitute of the robust ventral spines between the feet. 



Although he may have been right in regard to the identification of 

 his northern specimens, it seems to me as if his southern specimens 

 belonged to Fontaria crassicutis (Wood). 



Scutigera forceps is mentioned after Lithobius spinipes under the name 

 of Cermatia coleoptrata. His identification of onr species with the Eu- 

 ropean is wrong, although there is considerable resemblance between 

 the two.
