Remarks. Remarkably, despite being Singapore’s rarest amphibian, being known only from the type-specimen (Table 1), I. singaporensis was also the first amphibian recorded from Singapore. Ichthyophis singaporensis was first described as ‘ I. glutinosus Var?’ by Cantor (1847c) who received the specimen from Montgomerie in 1843 when it was dug up from his garden. Hanitsch (1908) incorrectly listed the collection date as 1863. Cantor (1847c) found the specimen to differ from I. paucisulcus, but did not find conclusive data to designate it as a new species. Ichthyophis singaporensis was later described as a new species by Taylor (1960). Taylor (1968) included three specimens collected from Peninsular Malaysia as part of I. singaporensis. The specimens are from “ Selangor ”, Batu Gajah, and Kuala Kangsi. As of today, I. singaporensis is only known from these four specimens. No live photographs exist of I. singaporensis, but Taylor (1960) provides a radiographic image of the specimen.
Occurrence. Only known from type-specimen predating 1847. Likely extirpated.
