These bars span the whole width of the upperside of the abdomen, being stronger at the angles than at the extremities. The spinners, six in number, are very short and inconspicuous. A single female, not yet adult, was contained in Mr. Melliss's collection. The pattern on the abdomen distinguishes it at once from any recorded species known to me. Fam. DYSDERIDES. Genus DYSDERA. DYSDERA CROCOTA. Dysdera crocota, C. Koch, Die Arachn. Bd. v. p. 81, tab. 166. figs. 392-394. Dysdera rubicunda, Bl. Spid. Great Brit. & Ir. p. 371, pl. 28. fig. 267 ; Cambr. P. Z. S. 1869, p. 532 (non D. rubicunda, Koch). Dr. Koch has lately sent me typical examples of Dysdera rubicunda (Koch) and D. crocota (Koch), from which it appears that D. rubicunda (Koch) is quite distinct from the Spider so recorded by Mr. Blackwall, the latter being the same as D. crocota (Koch). Examples of both sexes of D. crocota were received from Mr. Melliss in his recent collections, as well as in the former one. Genus SEGESTRIA. SEGESTRIA SENOCULATA. Segestria senoculata, Walck. Ins. Apt. vol. i. p. 268. Immature examples of what I believe to be this species were found among the St.-Helena Spiders received from Mr. Melliss. Fam. DRASSIDES. Genus GNAPHOSA (Latr.). G N A P H O S A LUGUBRIS, sp. n. (Plate XXIV. fig. 2.) Adult male, length 2\ lines. v. Cephalothorax oval, depressed, and almost devoid of any lateral constriction forwards, the normal grooves and indentations being nearly obsolete; it is of a deep blackish-brown colour, thinly clothed with pale adpressed hairs. The eyes, looked at from above and behind, are in two transverse nearly parallel rows ; the hind centrals are further from each other than each is from the hind lateral on its side, while those of the foremost row appeared to be as nearly as possible equidistant from each other. The height of the clypeus is equal to half that of the facial space; all the eyes (except those of the fore central pair, which are dark-coloured) are of a dull amber-colour. The legs are rather long, moderately strong ; their relative length seemed to be 4, 1, 2, 3 ; they are more or less of a dark greenish black-brown hue, except the tarsi and metatarsi (of the fourth pair |
