Tip of telson extremely blunt. Uropods with ciliate margin; outer rami as long as telson, inner just longer, and twice as broad as the outer. Anterior legs without teeth, but with a few short cilia; posterior legs with a few short spines along the lower border of the 3rd to the 6th joints; ungues short. X X . Genus S p h ^ roma Latr. 35. S peleroma f e l ix , sp. nov. (Plate X X X V . fig. 10.) Loc. ------ ? Thirteen specimens. Body gradually widening from the head to the abdomen, the telsonic portion of which narrows suddenly at the level of the base of the uropods, and thence rather more gradually to the posterior end. Eyes conspicuous, but small. The posterior portion of each of the thoracic segments is marked off from the anterior portion as a raised, broadish, transversely-grooved ridge ; the anterior portion, which is smooth, slides, in extension, under the raised portion, which is finely, but rather widely, granulate, as is also the cephalic segment. On the abdomen, and the upper surface of the inner rami of the uropods, the granules are larger, placed more thickly, and concealed under a rather dense, but very short, pubescence. The telson, from the base of the uropods, is bluntly triangular, with its margin non-granulate and reflexed upwards ; the inner ramus of the uropods is a little longer than the telson, the outer a little longer than the inner, with its upper surface smooth, and its outer edge fringed with short hairs and bearing 8 small teeth. A List of the Terrestrial Isopods. B y M. G usta v B u d d e - L u n d . 1. Ligia exotica Roux.-Several specimens; Kamlon, Singapore. 2. Trichoniscus antennatus, n. sp.-A few specimens of this little species (circa 5 mm. long), without information as to the locality. Distinguished by the very long and slender antenme, which have a long flagellum, 15-articulate; the antennae also, especially the first joint, are proportionally long. The uropods have the basal joint, and the exopodite, long and thick, the endo-podite very thin. 3. Philoscia truncatella, n. sp.- Two specimens, both with damaged antennae and uropods, from Gunong Inas, Perak, 5000 ft. Seems to be allied to P. truncata Dollf., from Celebes and Flores, but the last segment of the truncus is obliquely truncate only on the inside of the epimere ; also the transverse line on the epistome is a little sinuate, forwardly, in the middle.
