Lengths, maxillary palpus twenty-three mm.; labial palpus, eighteen mm.; first legs eighteen mm.; second legs twenty-two mm.; third legs thirty mm.; jaw tip to anus, thirty-three mm.; eyes to anus, twenty-five mm. : terminal joint of palpus continuous; tarsus apparently one jointed; head, seven mm. broad; five mm. long, with faintest possible trace of median striae; anterior border straight, oblique at angles, rounded at sides; broadly truncated behind; hairs very sparse, fine and short; eye prominence of medium size, slightly elevated, and slightly projecting, black in front and at the sides, pale behind, a few fine unequal hairs; eyes bluish, their interval greater than their diameter. Mandible, nine mm. long; base five and half mm. long; strongly convex; swollen at their base; furnished with fine spiny hairs; rather sparse and unequal; three obscure dorsal longitudinal bands on the base of each; teeth obtuse, two of medium size, fol1owed by one, rather large one, then a very small denticle, then the largest tooth of all, then two minute denticles; teeth then divide into two series, the outer with three teeth- the last smallest; the inner series with four teeth, the first largest, the third next, and the second and fourth, very small; the lower finger is a little shorter than the upper, and has two large teeth; the interior being largest, and with a small denticle on its anterior margin; the lower finger with a distinct lateral carina extending nearly to the point; brushes to the fingers as in the other Datames. Maxillary palpus; femur with a number of spiny hairs on the inside, especially on the ultimate portion; tibia and metatarsus also with a few irregular spiny hairs on the inside; more slender than those' on the femur; thickly clothed, especially on outside, with fine, short hairs, with a few very long ones intermingled; length, femur. six mm.; tibia six and a half mm.; metatarsus, five mm.; tarsus, one and a half mm., each enlarged from base to extremity; metarsus, and tarsus closely and rigidly united, but separation distinct; tarsus with numerous fine hairs. First legs slender, with fine hairs, without spines, without claws. Second legs, metatarsus, with six spines one side, four the other; tibia with two spines near the end, several weaker ones toward the base. Third legs, metatarsus with five pairs dorsal spines; three ventral spines; tibia, with few weak spines. Fourth legs, metatarsus, with row of about nine spiny  hairs on underside, besides the three regular spines; no spines on back; tarsus long, single joint with about four pairs of spines beneath; all the legs furnished with numerous fine hairs, some of them very long; tibia I, II, Ill, with terminal spine. Head and abdomen almost without hairs; first sub-abdominal segment with sub-triangular plate divided into two lobes by a longitudinal depression, which enlarges at about the ultimate two-thirds into a sublunar cavity, and this again after a slight contraction into a larger semi-circular cavity. Semi.circular depressions on posterior margins of second and third segments each with two spiracular openings.
