Philoscici incurva, n. sp.-Only one specimen, without the uropods and with damaged antennae, from Patalung. Differs from the other Asiatic species in the proportionally well-developed epimera of the caudal segments, which are acute and produced outwardly and backwardly; the last segment of the truncus has the hind margin very deeply incurvated. 5. Alloniscus brevis B.-L.-Many specimens from Patalung; a single specimen from Pulau Bidan, Penang. 6. Alloniscus sp. - Only one specimen of a little Oniscoid Isopocl taken at Bukit Besar. It is without the uropods, and seems to be akin to the Alloniscus albus Dollf. from Sumatra. 7. Metoponorthus pruinosus Brandt.-Eight specimens among specimens of Armadillo murinus Br. from Patani. 8. Lyprobius sp.-Only one specimen from Patani. This species is perhaps not different from L. cristatus, a species which is found in most tropical parts. I think also that Porcellio sun-daicus Dollf., from Sumatra, Java, and Celebes, belongs here ; and that P. pallidipennis Dollf. from Flores, and P. modestus Dollf. from Saleyer, should certainly also be included in this subgenus. 9. Toradjia conglobator, n. sp.- Three specimens from rotten wood at Ajenz (? Aring, W. F. L.), Kelantan. I know several species of this genus, in which M. Dollfus has included three species- T. celebensis Df., T. gorgona Df., and T. cephalica Df. The Perysciphus weberi Df. may be placed here, and T. conglobator is most nearly allied to this latter species, the first segment of the truncus not being split in the posterior edges, and the epistome being plain. The antennae are shorter than in T. weberi, with the flagellum short, white, and basal joint very short. 10. Armadillo murinus Brandt. - Several specimens from Patani. 11. Armadillo infuscatus, n. sp.-Several specimens from Goah Janat. This species and the next belong to the group of which A. murinus is the type, having the epimera of the truncus without folds in the hind margin of the first segment. This species is rather larger than A. murinus, and has the endopodite of the uropods much longer than in that species. The colour is a dirty pale yellow. 12. Armadillo pallidus, n. sp.- Six specimens from Bukit Besar. Very like A. infuscatus, but wrell separated by the form of the telson, which is not so strongly narrowed in the middle, and has the apex much longer than the basis; the basal joint also of the uropods is narrower. 13. Spherillo grisescens, n. sp.- Several specimens from Aring, Kelantan. This little species (5 mm. long) is remote from all |
