granite, gabbro, serpentine, melaphyre-like rocks, splierulitic 

 quartz- porphyry, and Tertiary eifusives make their appearance. 

 The Archsean is widespread in the Portuguese domain, accom- 

 panied by mica-schist and phyllite; and it seems highly probable 

 that the complex of crystalline schists extends through the islands 

 of Kisser, Letti, and Babbar as far as Burn, thus constituting the 

 second or outer arc of the Banda chain. 



At Ajer Mati, south of Kupang, already referred to, a red 

 Crinoidal limestone crops out at many points, which caused the 

 late Beyrich^'^^ and K. Martin^'^^ to write monographs, to the effect 

 that this limestone belongs to the Carboniferous. Lately Both- 

 pletz^'^ has worked over the collection made by Wichmann, and 

 has come to the conclusion that here we have the Permian or 

 Permo-carboniferous but not the Carboniferous. The collection 

 represents a rich fauna, together with Ammonites (Arcestes mega- 

 phyllus, A. tridens), resembling in many respects those of Salt- 

 Range, Armenia, and Texas. It is to be remarked that none 

 of the exclusively Permian species of Timor occurs in Australia 

 or iV m erica. Wichmann made a happy find near Baä in Botti, 

 lying oft' the south-west coast of Timor, where a limestone abounds 

 in bivalves upon the plane of sedimentation. These together 

 with other fossils, were also entrusted to Bothpletz for examina- 

 tion, who found many species of Halobia, Monotis, and Dao- 

 nella. Just as the Permian fauna did not show any close 

 relation to the eastern (Pacific) fauna, so also there are no 

 relations between the East Indian Triassic fauna and that of 

 New Caledonia, New Zealand, and Japan, where the 3Ionotis
