Red-Headed Reed Snake

discussion

Remarks. Some confusion regarding C. schlegeli occurred early on due to its variability in colouration (Cantor 1847 b; Boulenger 1894), with Taylor (1965) even citing Marx & Inger (1955) as stating that the Singapore population may typify a distinct race. However, a review of Marx & Inger (1955) does not corroborate Taylor’s (1965) statement. Cantor (1847 b) first reported C. schlegeli from Singapore from a specimen collected by Montgomerie. It was next reported by Boulenger (1894) who examined one specimen collected by Dennys and two specimens from an unknown collector. Sworder (1923) collected two specimens at BTNR. No specimens were deposited at the Raffles Museum early on (Ridley 1899), but Tweedie (1954) later reports seven specimens. There are presently three specimens at LKCNHM with no dates that may be part of Tweedie’s (1954) specimens, but the remaining specimens at LKCNHM were collected after 1994. Inger & Marx (1965) examined three specimens from the Raffles Museum, two from BTNR and one from “ Naval Base ” (= SNB). Inger & Marx (1965) also examined six additional specimens from Singapore from other museums. After this publication, the next field observation of C. schle
