    nostrils directed laterally, the other with the nostrils directed vertically upwards. The former group has a wide range. On the mainland, D. maculatus ranges from Yunnan to Singapore ; in Hainan it is replaced by the closely allied B. ivhiteheadi. Next come two species common to the Malay Peninsula and the three great Malay Islands, viz. B. volans and B.fimbricitus. B. punctatus is known from Borneo and the Peninsula, and there are three species confined to Borneo : these are B. cowiutus, B. rostratus, and B. cristatellus. Eastwards, B. lineatus has been recorded from the Moluccas and doubtfully from Java. Pour species are known to inhabit Celebes : one of these, B. reticulatus, occurs also in the Philippines, which have also six or seven ‘ precinctive ’ species. Lastly, D. walkeri and B. timorensis are found in Timor. On the other hand, the second group does not extend farther east than Java. It may conveniently be divided into two sub-groups : in one the gular pouch of the males is covered with very large scales, in the second the scales on the pouch are not enlarged. The first sub-group contains four species, these are:— B. blanfordi, from Tenasserim to Perak (Larut Hills). B. tceniopterus, Tenasserim and Siam. B. formosus, Perak and Penang. B. obscurus, Borneo. B. formosus is intermediate in structure between the first two species. Of the second sub-group, B. dussumieri is found in India; all the others are from Borneo, but some range into Java, Sumatra, and the Malay Peninsula :— Borneo. Java. Sumatra. Peninsula. B. maximus. B. a finis. B. quinquefascicitus. D. quinquefasciatus. B. micropterus. B. hcematopogon. B. hcematopogon. D. hcematopogon. B. melanopogon. B. melanopogon. On the whole the Peninsula comes nearer to Borneo than do any of the other neighbouring countries ; the other Agamoid lizards support this view strongly. The genus Aphaniotis is common to Borneo and the Peninsula, and not found in Java or Sumatra. The last-named island, on the other hand, has the precinctive genus Phoxophrys, and one species of the genus Cophotis, of which the other species is found in Ceylon, and belongs to a small group of three genera with processes on the snout otherwise peculiar to Ceylon. Java has the precinctive genus Harpesaurus, and is inhabited by Lophurus amboinensis, an eastern form belonging to that group of Agamoids furnished with femoral pores. There remain for consideration three large genera widely distributed in the Oriental region. One of these, Accinthosaura, is entirely continental and reaches its southern limit in the Peninsula. The second, Gonyocephalus, is chiefly found in the archipelago, as far east as N. Gfuinea; this genus is represented in the [«]
