given at the end of his work (/. c. pp. 244-248). This, which is 
the final result of his investigations, presents some slight altera- 
tions upon that of Newport, as will be seen from the following 
abstract of his groups : — '

Wood maintains {Lc, p. 178) that GcopTiilus carpopJiagu8 is 
to be regarded as the type of the genus GeojiMlus of Leach> and 
the latter name must therefore be applied to the section of the 
old genus which includes that species, which was named Artlira- 
nomalus by Newport. To Geophilus of Newport he applies 
Gray^s name Strigamia. The total number of North American 
species described by Wood is 94, of which only 3 are new, the 
new species having been described by him in 1863 and 1864 in 
the Journal of the Academy of Natural Sciences of Philadelphia. 
Several of these are here figured.
