The two specimens show very decided differences in the form of the forceps. In one individual (Fig. 33) they are moderately robust at the base, the internal margins are arcuate sublamellate in the proximal third and appreciably^ crenulate; distad of this section the arms of the forceps are arcuate toward and cross- ing one another, rounded in section in the median third, the external margin convex, the internal concave; at distal third the internal margin has a distinct, flattened, lobiform tooth; distad of this the arms of the forceps are weakly falcate to the acmninate apices. The other , ^^; ' ^*" type has the forceps somewhat more slender, tapering, ^^^^ (Bore) Male straight and subparallel in the proximal half, then Faradje, Congo, gentlv and regularly falcato-arcuate toward and cross- Apex of abdomen '^ " . ... from dorsum, X9. ing one another, the apices acute; mternal margm m proximal third serrulate; no apparent indication of tooth at distal third. In both types the forceps are seen, in profile, to be curved dorsad in dis- tal two-thirds, the tips very faintly decurved. There is no question in my mind as to the specific identity of the two specimens, but to aid future workers details have been given above. In size the individuals are rather small, the body length b
