27.8.1807 Siboya, w. T(homas) T(urner)
See Jackson's Oxford Journal 17.10.1807 just arrived in Oxford, the great Siboya serpent, brought home in the Sir William Bensley East Indiaman. 12 feet long, muticoloured, harmless. I could find no reference to where it was shown in London. See Caroline Grigson's Menagerie (2016) page 93
