In the following key to the .specie.s of Seolopendra I have adopted 

 Poiath's name CoUaria as a siibjifenns iiH'lndin«r all species whieh have 

 the femora of penultimate pair of legs spinous. The other groups es- 

 tablished, T think, are not worthy of subgeneric rank. 



* As Branchiosioma Newport is )»reocrMi]»ipd (Costa. Pisces. 1S34), lihynida Wood 

 must be used instead. 



t Hcleroatoma Newport preoccupied (Hartm., M(dl.. IHi'A) and Dacetum Koch must 

 take its place.
