Results and discussion There were noted the following differences between R. I. pemiger (3073, Jaintia Hills, Figs 1, 2, 3) and R. I. beddomei (3081,Pune, Figs 4, 5, 6) in the Bombay Society's collection. The skull of R. beddomei is found to be much smaller with relatively greater zygomatic width, with much shallower hollow above the interorbitalia. The backward-curving hook of premaxilla is shorter and thus the central hole is not closed as in R. I. pemiger. The premaxillae join the maxillary palate with an absolutely wider base than in R. I. pemiger. The opening of the choana between pterygoids, that is, the palation is identical to the one in the other form, however, smaller. The bulla tympani in R. beddomei is less inflated. The upper toothrows of R. beddomei are anteriorly nearer to each other. The upper C and P 4 are of smaller basal crosssection, apparently because of their less developed cingula in R. beddomei. The upper C of R. beddomei on its extero-posterior base has no impression for P 2 as in R. I. pemiger. As regards the differences in the mandibles of the two forms, the coronoid process seems more narrowely pointed in the smaller mandible of R. beddomei. The lower C is antero-posteriorly more shortened and also the P4 is much shorter than in R. I. pemiger. The less sloping labial cingulum of the latter is but with a slight wave in R. beddomei. The talonid of M3 of R. beddomei is much wider and also wider than its trigonid, just opposite to the case in R. I. pemiger. The authors recently studied the skulls of the available specimens (except types) in the collection of The Natural History Museum, London (Figs 7, 8, 9) and the skull of the specimen in the Budapest collection from Vietnam (Figs 10, 11). Disregarding the few specimens from Thailand, collected in the seventies, the collection of the skulls in London is about the same as in Andersen's time. Statistical data Generally speaking, especially the cranial measurements of R. beddomei are smaller than those of others as shown by the basic statistical data (see Tables 1, 2, 3,)Table 1.
