Cyclemys orbiculata Bell, 1834: p. 17

Current name: Cyclemys dentata (Gray, 1831)

Syntypes (3 specimens): OUM 8512 (Bell Collection, Catalogue of Testudinata No. 24a; shell, SCL 19.9 cm, bears small label with number “110”; also syntype of Emys dhor = Emys dentata Gray, 1831 ); OUM 8513 (Bell Collection, Catalogue of Testudinata No. 24b; shell, SCL 19.1 cm, bears small label with number “111”; also holotype of Cyclemys bellii Gray, 1863 and syntype of Emys dhor = Emys dentata Gray, 1831 ); OUM 8867 (Bell Collection, not listed in the Catalogue of Testudinata; shell, SCL 5.6 cm; also syntype of Emys dhor = Emys dentata Gray, 1831 ).

Remarks: It is clear from the original description of Cyclemys orbiculata that several shells served for the description. Consequently, we treat all shells of Cyclemys dentata present in the Bell Collection as syntypes of Cyclemys orbiculata . Furthermore, Bell (1834: p. 17) mentions that the hatchlings listed by Gray (1831a) under the name Emys dhor represent the same species. Therefore, these specimens from the Natural History Museum, London, have syntype status for Cyclemys orbiculata as well. The two syntypes OUM 8512-8513 were figured in Bell’s (1832–1836) Monograph of the Testudinata (part 8, plates 2 and 3, reproduced as plates XXIV and XXV by Sowerby & Lear 1872).

Using mitochondrial DNA sequences (partial cytochrome b gene) of two Cyclemys orbiculata syntypes (OUM 8512-8513), Stuart & Fritz (2007) confirmed the previous assessment of Fritz et al. (1997) that Cyclemys orbiculata Bell, 1834 is a junior synonym of Emys dentata Gray, 1831 .
