C Amphibians and reptiles from northern Trengganu, Malaysia, with descriptions of two new geckos : Cnemaspis and Cyrtodactylus J. C. M. Dring a-K^ 22 Fryston Avenue, Croydon CRO 7HL Synopsis A collection from the area of Gunong Lawit, northern Trengganu, Malaysia, is described. Records of interest for West Malaysia are of Microhyla borneensis, Rana p. paramacrodon and Rhacophorus pardalis. Two new lizards, Cyrtodactylus elok and Cnemaspis argus, are described, and a key to the species of Cnemaspis in southeast Asia is given. Goniocephalus herveyi (Boulenger) is a synonym of Goniocephalus liogaster (Giinther). Introduction Gunong Lawit is a mountain rising to a height of 1519 m (4982 ft) on the border between Ulu Trengganu and Ulu Besut in northern Trengganu State. During the period 22 February to 9 April 1974 an expedition of the British Museum (Natural History) collected certain groups of insects, amphibians, reptiles and some small birds and mammals on G. Lawit and in the lowlands to the east of it. Most collecting of amphibians and reptiles was conducted from three camps, at the Sungei Kelebang and on the east ridge and summit ridge of the mountain. The Sungei Kelebang camp, 102 45' 0" E 5 27' 40" N, at 43 m elevation, in Mukim Ulu Setiu, Ulu Besut, was in an area of regenerating forest that had been selectively logged in 1971. The riverine forest (Saracca stream vegetation) had been little disturbed but the other areas were a mosaic of secondary forest and relatively untouched dipterocarp forest, intersected by logging tracks. The Kelebang drainage is separated from that of the Sungei Petuang by a ridge, Bukit Bok, rising to a height of some 600 m and forming the boundary between Ulu Besut and Ulu Treng-ganu. A transit camp on the Sungei Petuang, 102 38' 20" E 5 26' 20" N, at 250 m, was beyond the reach of the loggers and was surrounded by primary rain forest on the steep hillsides leading to the mountain. The east ridge camp on Gunong Lawit, 102 37' 18" E 5 25' 25" N, at 790 m, was on a ridge top in submontane forest covering the flanks of the mountain. Despite the well-lit forest floor the shrub story was sparse, including mainly palms, such as Johannesteysmannia. Most of the collecting was carried out along two swift streams, incised into each side of the ridge, which had their sources not far to the east of the camp. On the summit ridge, 102 36' 20" E 5 25' 20" N, at 1280 m, the camp was in montane rain forest, with Leptospermum and Dacrydium prominent among the trees, a thick understorey of shrubs and palms, and scattered areas of open 'padang', a heathy association of grasses, ferns and small shrubs. Material collected GYMNOPHIONA Family ICHTHYOPHIIDAE Ichthyophis sp. MATERIAL. BM. 1974. 4229 ($). HABITAT. This specimen was found dead at the edge of a small rocky stream near the Sungei Kelebang camp. The stream had compact gravel beaches of very limited extent, and almost lacked silt, but may have drained from a more favourable area for caecilians. Bull. Br. Mus. nut. Hist.
