Noetling (Pal. Ind., N.S., vol. i, p. 6) intended to have substituted his own terms “Bassein” and “Chin” Divisions for Theobald's “Nummulitics” and “Axials” respectively, but he made serious errors in definition which invalidates his classification (see Pascoe, , Mem.

^{page 498 note 1} Dr. Pilgrim, G. E., in his revision of the vertebrate fossils of the Irrawadian of Burma (Rec. G.S.I., vol. xl, pt. iii, 1910, p. 196)Google Scholar, has confused the specimens from these two horizons. He gives them in one list and says “It seems certain, however, that from the lowest beds [sic] of the Irrawadi seriesboth Noetling and Grimes collected a distinctive vertebrate fauna which I have examined. …. ” If, however, one consults Noetling's account (Mem. G.S.I., vol. xxvii, pt. ii, 1897, especially pp. 57, 58, and 59) one finds he says “specimens are particularly common along the river bank between Yenangyoung and Nyounghla…. ”; again, “ I am absolutely sure that certain species are restricted in the neighbourhood of Yenangyaung to the lower parts of the division…. ”; then, after separating a lower “zone” of Hippotherium antelopinum and Aceratherium perimense from a higher “zone ” of Mastodon latidens and Hippopotamus irravaticus he says that the two latter almost certainly do not occur lower. Grimes (Mem. G.S.I., vol. xxviii, pt. i, 1900, pp. 30–79) separates the Irrawadian into four “zones”; from the lowest he only mentions Cervus sp., then after describing his highest “zone” as being exposed along the banks of the Irrawaddy says “It was from conglomerate beds of this zone that Mr. Crawfurd, Dr. Oldham, and in late years Dr. Noetling have obtained numerous fossil vertebrate bones…. ” (p. 64). The writer's personal experience confirms these statements.
