triangular convexity; the prosepistoma is continuous with the 
forehead in the middle and separated from it on both sides by a 
transverse, incomplete, preocular cut. Eyes moderate ; ocelli about 
12. Antenne short; flagellum small, first joint four times shorter 
than the second. Pereion: first segment with the antero-median 
tubercle hardly perceivable; coxopodites distinct on the entire 
length of the edge of the segment. Coxopodite of the second segment 
hidden under the bent side part of the segment. Pleon, telson: 
the lateral parts being nearly folded underneath, the hind edge 
of segments 3-5 seems straight from a dorsal view. Pleotelson 
flat, with curved sides and a blunt, rather rounded apex. Uropoda: 
basis with a large oblong processus; endopodite reaching to two- 
thirds the length of the pleotelson ; exopodite small, placed at the 
top of the basal processus. Colour: dark brown, flagellum 
whitish. Dimensions: 5x2 millim. (much decreasing backward).

HAPLARMADILLO, gen. nov. 
Very much like Synarmadilo, Dollfus*. It differs from this 
African genus in its monocellated eyes, and in the flagellum being 
single-jointed (this is quite an exception in Armadillos).
