The last joint as long as the two preceding ones together. The different sense-hairs described in alluaudi by Ribaut are present also in this species. Of the first kind, viz. short, conical bristles, three are present on the dorsal side of the ninth and thirteenth joints, situated close together on the inside. The second kind of hair, short and cylindrical with a fine terminal point, is. Text-fig. 46.—Ballophilus braunsi Silv. Clypeus and labrum. present on several joints. Here these hairs are pale, not dark coloured as in alluaudi, and therefore inconspicuotis. The material examined is limited, and I cannot say on which segments they are wanting. I saw them on segments 2, 3, 4, 9, 13. The labrum is short and fused with the clypeus. The free margin is provided laterally with one moderately distinct and one or two rudimentary teeth ; the middle part is rectilinear and smooth (text- fig. 46). Clypeus short, the reticulation not distinct. Two post- antennal bristles close to the frontal margin, behind them six bristles in an arch. First maxillae (text-fig. 47) with two bristles at the base of the coxal process ; the process hairless. The basal joint of the telopodite with a little lateral lobe turned to the oral side. Distal joints with one long bristle. Second maxillae : in the only specimen examined I could not see a median suture in the coxosternum. Ribaut found a suture in alluaudi, but possibly
