Indochinese Rat Snake (Ptyas korros) at Sembawang

Location, date and time: Singapore Island, Sembawang, Sembawang Road at junction of Canberra Street; 31 January 2017; around 1315 hrs.

Observation: The featured snake was found wriggling on the busy road after having been struck by a car. The observer retrieved the injured snake with the intention to revive it. Although the reptile appeared intact externally, it had suffered from internal injuries and soon died. The accompanying picture shows a dorsal view of the specimen ex-situ shortly after it had expired.

The snake was deposited as a voucher specimen in the Zoological Reference Collection of the Lee Kong Chian Natural History Museum at the National University of Singapore, where it was assigned the catalogue number ZRC 2.7238. It was found to be an adult female, measuring 154 cm in total length, and 100 cm in snout-vent length.

Remarks: In Singapore, the Indochinese Rat Snake ‘appears to be fairly common in rural areas where it feeds on rodents and frogs’ (Lim & Lim, 1992: 56). Baker & Lim (2012: 161) do not illustrate this species in their guide book, but regard it as a native species that is locally ‘widespread but uncommon’.

Dead White-bellied Blind Snake (Typhlops muelleri), Jasper Cat Snake (Boiga jaspidea), Brown Tree Skink (Dasia grisea) at Upper Peirce

Location, date and time: Singapore Island, Central Catchment Nature Reserve, access road to Upper Peirce Reservoir Park, off Old Upper Thomson Road; 27 August 2016; evening.

Observation: A juvenile Typhlops muelleri of about 10 cm total length (Figs. 1 & 2) was found dead in water in a drain. It is believed to have drowned. A male example of Boiga jaspidea of about 1 m total length (Fig. 3), and an adult Dasia grisea (Figs. 4 & 5) are both flattened and dried roadkills found plastered on the surface of the road. They have probably been dead for more than a day.

Remarks: The three species of reptile herein recorded are recognised as rare in Singapore. Boiga jaspidea and Typhlops muelleri are classified as ‘critically endangered’ while Dasia grisea is regarded as ‘endangered’ (Lim, 2008: 264-265).

All three specimens have been deposited at the Lee Kong Chian Natural History Museum at the National University of Singapore, with Boiga jaspi
dea
catalogued as ZRC 2.7225, Typhlops muelleri as ZRC 2.7226 and Dasia grisea as ZRC 2.7227.
