![DIPLOPODA. Order HELMINTHOMORPHA. Sub-Order Co l o b o g n a t h a. SiPHONOPiiOBA LONGiEOSTBis Silvestri. (PlcTte XXX. figs. 1-3,5.) Prom Kuala Aring, Kelaiitan State. Silvestri’s description is very short, but I thiuk that this species must be identical with the one from New Gruinea described by him, or, at any rate, very closely allied. Length 45 mm., width 3 mm. Number of somites 93. Colour red-yellow, shading into pale yellow from the sixth somite to the head ; legs pale yellow. Head with long, slender, curved beak. Antennae a little longer than the beak ; terminal joint large and rounded, other joints equal. Antennae and head covered with close-set hairs. tergite curved where it joins the head, broad, about double the length of the succeeding tergite. Keeled like the others. Pores situated on the keel. The side below the keel runs straight down to join the pleurae at a fairly sharp angle, thus making the shape of the body rather square than cylindrical. Legs very short and thickly haired ; joints about equal, enhng in a blunt claw. Anal valves rather small, one sternite behind the anus without legs and divided by a median longitudinal furrow. Body tapering very gradually before and behind. Platydesmus kelantanicus, sp. nov. (Plate XXX. figs. 4, 6-9.) From Kuala Aring, Kelantan State. Colour dirty brown ; head clear yellow; legs and sterna pale yellow. The largest specimen has 79 somites ; length about 50 mm. by 5 mm. The smallest 77 somites ; length 43 by 4| mm. Head heart-shaped, small, covered with very fine short hairs. Antennae (fig. 9) short and thick, nearly equal joints, the second being a little the longest. The hypostoma (fig. 8) has the maxillae large, inframaxilla single, large at base, contracting rapidly to a spike-shaped elonga- tion, which extends almost the whole length of the hypostoma; galeae small; small cardines ; basals normal; maxilla furnished with a few bristles at the anterior edge. Mandible with a long slender shaft, then a short movable joint, then a pectinated terminal portion (see fig. 7) consisting of a row of bristles supported by a slender shaft which has a ring at some distance from the end which looks like a joint, but is, I believe, immovable.
