. Bulletin of the British Museum (Natural History). PEBASIAN FAUNAS 323. he owed his material to the kindness of Dr W. Kobelt of Schwannheim, who, in turn, had received it from Herr R. Abendroth of Leipzig in 1877. A letter from the last-named gentleman which accompanied the fossils mentioned that the village of Pebas was 'forty miles above the Brazilian frontier fort of Tabatinga . .. The fossils came from a blue clay at one place near the town . . Abcndroth's fossils came from Mr Hauxwell, an Englishman, who spent several years in the region Thus, the arguments as to whether or not all Boettger's material came from Pebas itself are fairly evenly balanced. He was clearly aware of the presence of the other localities and hence of the possible confusion. On the other hand, part of Abcndroth's letter read like a translation into German of the description of Pebas and its relation to Tabatinga given in Hartt (1872). This raises the suspicion that this letter was not based on first-hand observations by the collector Hauxwell. Hauxwell certainly had the time to revisit Pebas. Boettger's fauna has much in common with those described by Conrad and Woodward mainly from Pichana. The true Pebas fauna so far known is very small and the fossils were said (Orton, in Conrad 1871ft) to be more common at Pichana. However, Orton's visit to Pebas was, in any case, so short that he may well not have done that locality justice. The bulk of the collection is in Senckcnburg Museum, Frankfurt, and has not been studied herein. The holotypc of Pseudolacuna macroptera Boettger was rcfigurcd by Cossmann (1915) and is now in Univcrsitc de Paris (Kadolsky, 1980: 372-373), who rcfigurcd it. Kadolsky also refigured (1980: fig. 10) the holotype of Eubora bella semisculpta (Boettger). Several of Boettger's specimens were rcfigurcd by dc Greve (1938): details arc noted in the [quitos faunal list given here (p. 332). Species not figured by Boettger arc indicated by '(no fig.)' in
