Show 394 MR. R. I. POCOCK OX SOME [Dec. 2, 24 mm., whereas a female of P. leppancn measuring 9 mm. has a second leg of 33 mm. in length. The female of this new species is a genuine Phalangium, whereas the male approaches Rhampainitus. The genus Rhampsinitus Simon (CR. Soc. Ent. Belg. 1879, p. lxxii) appears to me to rest upon an insecure foundation. The species I have described below as Phalangium (Rhampsinitus) telifrons and spenceri differ from P. leppance only in the greater length of the mandibles and the greater size of the inferior spines of their basal segment in the male.

Colour of trunk light olive-grey above, with a paler yellowish median longitudinal line, 1 mm. wide, extending from the ocular tubercle with a sinuous darker line external to i t ; chelicerte yellowish brown, indistinctly banded longitudinally, the spines on the basal segment black-tipped above, second segment mottled with darker spots without and within; legs yellowish red, darker apically; coxae clouded with chalky white; abdominal sterna whitish. Text-fig. 79. A. Carapace and mandible of male P. (Eh.) spenceri, and B. Carapace of P. (Bh.) telifrons. Upperside of body finely and closely granular; carapace (text-fig. 79, A) with two pairs of spiniform teeth on each side of the tubercle, a few marginal by Krohn's stigmata, and many on the ante-ocular portion, that on the middle of the front border being conspicuous; the tubercle with four pans of sharp spiniform teeth; a deepish transverse groove, followed by a row of spicules, running to the base of the 3rd leg behind the ocular tubercle ; this is followed by six transverse segmental rows of sharp spicules, |
