The _Eyes_, eight in number, are seated on a transverse oval eminence, and form a rectangular figure, whose transverse diameter is double the length of its longitudinal diameter: their relative position is similar to that of _Cteniza_, but in the present species they are smaller than in _C. fodiens_: those of the hind central pair are the smallest of the eight, and each is very nearly contiguous to the hind lateral on its side; the interval between those of each lateral pair is small; the space between the two central eyes of the eight is equal to an eye's diameter, and each of these is separated from the hind central and fore lateral nearest to it by a similar interval. The _Legs_ are strong, moderately long, their relative length 4, 1, 3, 2?, but little difference is observable between 1, 3, and 2; they are furnished with hairs, bristles, and a few, not very strong, spines; each tarsus terminates with three curved claws, the two superior ones much the longest and strongest, and have a few small teeth near their base inside. The _Palpi_ are strong and similar in colour and armature to the legs; each is terminated with a curved black claw. _Falces_ strong, prominent, and rounded in the profile line; they are furnished with hairs, bristles, and strong tooth-like spines; the four strongest of these latter form a transverse row at the inner extremity of each; besides these there is a row of short tooth-like spines on the inner margin of the furrow on the underside of each falx, in which the fang lies concealed when at rest. The _Maxillæ_ are strong, with a small angular prominence at their inner extremities (when looked at from beneath), and each has three to four small dark-coloured teeth in a short, straight, obliquely transverse row at the base on the inner side. _Labium_ broad but short, its breadth is double its height, and the upper corners are rounded off. The _Sternum_ is of a somewhat pentagonal form. _Abdomen_ rather elongate oval, tolerably, but not excessively, convex above; it is of a dull yellowish whitey-brown colour marked and mottled above with dark chestnut brown; the markings are rather irregular, but a general disposition in the form of a longitudinal central, and oblique lateral, stripes or bars may be traced on the hinder half; the superior spinners are short and three-jointed, those of the inferior pair are exceedingly minute. Adult females were found in nests similar to those of _Cteniza fodiens_.
