 from Venezuela, and thus far only two species have been referred to it. I am unacquainted with the genus and, from Simon's brief treatment of it, I am unable to come to any decision as to the correct placement of this species. The Peckhams had a species in their collection which they labelled Akela, new. This appears to be very close to A. incertus Banks. The Peckhams established the genus Akela on the species A. charlottae from Guatemala. I think the species under consideration here is not an Akela. I know nothing better to do with it for the present than to retain it here pending further knowledge.

Male allotype. Total length 3.20 mm. Carapace 1.50 mm. long, 1.20 mm. wide at level of PLE which occupy forty-eight fifty-thirds of the width of the carapace at their level; very little narrowed in front; fairly high; shaped much as in Zygoballus; slightly more than three quarters as high as wide; gently arched dorsally for nearly six sevenths of length to posterior declivity which is slightly concave and descends abruptly to posterior border (Fig. 214).

Eyes. Seen from in front, anterior row strongly recurved. Posterior row wider than anterior row in ratio of 49 : 45, middle row slightly narrower than anterior row. Quadrangle of laterals wider than long in ratio of 49 : 29. Total eye space occupies almost half the length of the carapace. Ratio of eyes AME : ALE : PME : PLE = 14 : 7 : 1.75 : 6. AME separated from one another by a little less than one fourteenth of their diameter, from ALE by nearly one seventh of their diameter. Eyes of second row equidistant from ALE and PLE. Height of clypeus equal to a little less than three fourteenths of the diameter of AME. A fairly conspicuous small tuft of white scale-like hairs projecting downward from beneath each AME.

Chelicerae. Robust, quite porrect, considerably produced; divergent beyond the basal third; with well developed basal boss; basal segment .80 mm. long; most of front surface covered by long white procumbent hairs, somewhat erect along dorsal edge. Fang fairly long and slender, slightly sinuous. Fang groove distinct, with a single robust retromarginal tooth near base of fang, and two promarginal teeth, one near base of fang and the other near medial end of groove.

Maxillae. Parallel; considerably dilated distally; quite concave along outer border; palp inserted into proximal half; longer than wide in middle in ratio of about 2 : 1; with well developed scopula along truncature and the usual serrula.

Lip. Widest at base where it is as wide as long; distal margin regularly convex; basal excavations reach less than one third of length of organ; sternal suture slightly procurved.
