Scale counts and external observations of morphology were made using a Nikon SMZ-10 dissecting micro- scope. Radiographic observations were made using a Faxitron enclosed radiographic unit. Comparisons were made with museum material in the collections of the California Academy of Sciences (CAS), Field Museum of Natural History (FMNH), and Institut Royal des Sciences Naturelles de Belgique (IRSNB) (see Appendix), as well as original published descriptions and descriptions pro- vided in broader faunal treatments (e.g.. Smith, 1935; Taylor, 1963).. 'li vt: Dixonius hangseesom, sp. nov. Figs. 1-6 Holotype Chulalo
