GEOPHILOIDEA FROM LIBERIA AND TOGO, 
This group of Chilopoda is represented in Liberia by a few specie s 
w hich were named, described and figured over two years ago, but 
*^blication is still delayed, so that preliminary descriptions are offered 
here. 
The Liberian fauna is remarkable in that it seems to contain no 
species of the genus Geophilus, representatives of which have been 
described from all parts of the world, though many such reports are 
probably based on insufficient examinations. Thus in a recent paper 
on the Myriapoda of Kamerun Porat has described seven new species 
under Geophilus, of which few, if any, are true Geophili, and some 
of which differ from Geophilus by family characters. Of the several 
families and genera of Geophiloidea * those thus far collected in 
Liberia may be distinguished from each other by the following 
synopsis : 
Labial sternum divided ; prehensorial sternum very narrow, without chitin- 
ous lines ; anal pleuree inflated, with numerous pores ; sterna with a median 
y-shaped chitinous thickening ; Family Dicellophilidae. The genus Lamnonyx 
Ck. has the frontal lamina incompletely chitinized in front of the labrum, 
the margin of the labrum entire, and a claw-like callosity at the anterior 
corner of the cephalic lamina below. 
Labial sternum entire ; prehensorial sternum broad or with chitinous lines ; 
anal pleurae with few pores or eporose ; sterna without median chitinous thick- 
enings. . . . . . . . . .... 
Mandibles with a single pectinate and no dentate lamella ; labrum tripartite; 
claw of maxillary palpus simple : Family Geophilidae. The only Liberian 
genus is Schizotmnia Ck. which is distinct from Geophilus in the divided max- 
illary sternum, the distinct prosternal teeth and prominent claw of the prehen- 
sorial legs, the want of ventral pores and the compound or spinose claw of the 
anal legs. 
Mandibles with several lamellm, or at least with both pectinate and dentate ; 
labrum entire ; claw of maxillary palpus pectinately fringed. 
Ventral pores distributed in 2-4 indefinite areas located on the anterior and 
posterior parts of the sterna so that a central space is poreless ; a small sclerite 
above the spiraculiferous scutellum : Family Oryidse. The species which I 
have identified as OrphncBus phosphoreus (Linn.) is probably not indigenous in 
Lrrangement of the Geophilidse, Proc. U. S. Nat. Mus. XVIII, pp. 
ted ; ftrei^diagnosis are given in the appends 
^ list of West African species.
