SINGApoRE Isla Nd, 1° 24' N. L. 104° E. Mean annual temperature, 80°. Greatest daily range of thermometer: 10°. Annual number of rainy days: 185. Surface gently undulating. Sand-stone hills, indicating remote convulsion; highest hill (Bukit Timah) 530 ft, granite. In the valleys occur vegetable and animal forms which at Pinang have been observed at or near the summit of the hills, but not in the plains. Thus at Singapore, occur Alsophila, Schizaea, Tucca cristata, Gnetum, Nepenthes, Begonia, Eurycoma and others, which at Pinang appear to affect a much greater elevation. Instances of Reptiles in common to the plains of Singapore and the hills of Pinang are: Psychozoon homalocephalum, Gymnodactylus pulchellus, Lygosoma chalcides, Pilidion lineatum, Typhlops nigro-albus, Calamaria lumbricoidea, War. Leptophis caudalineatus, Elaps intestinalis, Elaps nigromaculatus. MALAYAN PEN IN's ULA. Geographically, not politically, from 12° N. L. between 98° and 104° E. computed to about 80,000 square miles, or about 4000 square miles less than Great Britain. Zoological information has hitherto been confined almost exclusively to the plains of the western part. The productions of the chain of mountains dividing the Peninsula, and terminating in Cape Romania in 1° 17' N. L. (Point Būrus in 1° 15' N. L.) are almost entirely unknown. The late Mr. Griffith on a visit in the early part of 1842 to mount Ophir (Gúnong Ledang, in about 2° 30' N. L. on the eastern boundary of the district of Malacca, granite, and computed about 4000 ft.) made the interesting discovery, that from 1500 ft. and upwards the vegetation changes completely, and in many respects assumes a Polynesian or Australian character. Early in 1847 Lieutenant Colonel James Low visited Keddah Peak, (Gúnong Jerai,) opposite to the town of Keddah, in about 6° 5' N. L. which he observes is not granite, but stratified, abounding in minerals. According to observation of the boiling point of water, the summit, a small platform on the edge of the strata, is 5,705% ft. above the sea. Towards the summit the vegetation becomes very stunted and partakes of Australian character.” Colonel Low further observes that during the ascent he did not see a single animal, but found foot prints of a Rhinoceros, smaller than usual, he supposes, up to the very summit. To a casual visiter of the Malayan hill forest, during the day, the paucity of animals is a striking feature. The noonday light subdued by the dense foliage of the towering stems, gives to the scene a sombre character, heightened by the unseen denizons. Their presence is manifested in the shrill vibrations of Cicadae, one of which on the Pinang hills is noted for its resemblance to the cavalry trumpet, the call of the Tupai, the dismal tap of the gigantic woodpecker, the creaking flight of a Buceros, or the retreat of frightened Semnopithecs.

* A collection of plants from the summit of the mountain, with which Colonel Low favoured me, were examined by Capt. Munro, H. M. 39th Regiment, the only botanist at present in Calcutta, previously to their being despatched to the Royal Gardens, New
