C. Z. 11232) Mushongero, Lake Mutanda, southwestern Uganda. 1. ii. 39. 14 d" 3 9 (1 ovigerous) (M. C. Z. 11232), same data. Carapace relatively narrow, nearly three-fourths as long as broad, moderately convex in both directions and with the regions fairly well delimited. Surface with a few scattered punctae but more or less smooth and polished to the naked eye. Post-frontal crests dis- cernible, but rounded off so that they are more or less indistinct in the. Fig. 4. Potamon (Geothelphusa) mutandensis; male holotype, x adult except for the protogastric prominences; the crests are more prominent with a tendency to become sharp-edged in females and young. Anterior mesogastric region roof-shaped and marked off by a very faint line which may extend nearly to the frontal margin, but is usually almost invisible. A rather deep, H-shaped depression delimits the posterior gastric and cardiac regions from the branchial region, and there is a broad depression separating the branchial region into two parts; this last depression usually, but not always, curves down onto the side wall sufficiently to make the postero-lateral margin slightly concave. Front typically strongly bilobed in dorsal view and turned.
