Norr.—The following characters apply to all the species falling under A in the above table; some, however, 
in the case of the eyes and the mouth-parts, apply also to B a and Bb 2:—Kyes closely grouped ; anterior row 
more or less procurved ; eyes equidistant, or almost so. Labium not less than half the length of the maxille. 
Maxille short, broad, not straight, but curving inwards, convex on the outer side, not dilate at the apex. 
Trochanter of pedipalp attached more nearly at the middle of the maxilla on the outer side. No central 
apical protarsal spine. Carapace gradually inclined to its base, not precipitous behind the cephalic region, 
slightly convex at the central fovea, not concave, narrowed in front. Sternum scarcely longer than broad, 
almost circular. Lower margin of fang-groove with from 5-7 teeth.
