the middle line ; these swellings just meet at the middle line, and 

 from their junction proceeds a very short longitudinal median 

 swelling ; the rest of the upper surface smooth and slightly 

 convex. Tip of telson extremely blunt. TJropods 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. 



XX. Genus Sph^roma Latr. 



35. Sph^roma FELIX, sp. nov. (Plate XXXV. fig. 10.) 



Log. ? 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. 

 By M. GusTAv Budde-Lund. 



1. Ligia exotical^ova.. — 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 antennae, 

 which have a long flagellum, 1 5-articulate ; the antennte also, 

 especially the fii-st 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. Another small,
