The ipil is a critically endangered tree in Singapore (Chong et al., 2009). This species usually inhabits back mangroves, much of which in Singapore was destroyed due to land development.

The ipil, usually found in mangroves, is a critically endangered species in Singapore (Chong et al., 2009).

The specimen was compared with skeletons of small cetaceans in the Zoological Reference Collection of the Lee Kong Chian Natural History Museum, which include the Irrawaddy dolphin and the finless porpoise (Neophocaena phocaenoides). The morphology of the upper jaw and palate, and mandible (Fig. 2) is that of an Irrawaddy dolphin. The mandible is distinctive in being slender with a concave ventral margin. The Irrawaddy dolphin grows to a maximum total length of 2.75 m, and occurs in the shallow coastal waters, estauries and rivers of India, Bangladesh, Myanmar, Thailand, Malaysia, western Indonesia, Cambodia, Vietnam and the Philippines (Shirihai & Jarrett, 2006: 244). Although two museum specimens from Singapore have been reported (Sigurdsson & Yang, 1990: 32), there appears to be no published recent record from there. Because of this, the species is not listed in the Singapore Red Data Book (see Lim et al., 2008). The present specimen confirms the presence of this small cetacean in the area, but its national population status is still indeterminate.

The northern chevrotain, Tragulus williamsoni Kloss, 1916, was described, and for nearly a century remained known, from only one specimen. This had been collected from Meh Lem in northern Thailand in 1916. Following a taxonomic revision of the genus Tragulus, its taxonomic status was regarded as uncertain. New information from a Tragulus specimen from Xishuangbanna, Yunnan province, China, stored in the Kunming Institute of Zoology, corroborates the status of T. williamsoni as a distinct taxon based on skull measurements. The conservation implications of this finding include the urgent need to determine conclusively the taxonomic status of T. williamsoni, and its distribution and conservation status.
