526 RevieiDS — Br. Fritz Noetling — Miocene Man in Burma. 



3. Group C. Hard and soft sand-rocks, alternating witli light- 

 brown clays. Silicified wood common, and remains of land and 

 fresh-water animals. Thickness not less than 4620 feet. 



2. Group B. Brown and red sandstones and light-brown clays, 

 containing numerous crystals of selenite, and locally countless 

 numbers of Batissa Craw/ordi, Noetl. ; terminating in a bed of 

 ferruginous conglomerate with numerous remains of terrestrial 

 animals, among which Hipp other ium \^nipparion^ antelopinum, 

 Cautley and Falconer, and Rhinoceros Perimensis preponderate. 

 Chipped flints locally not rare. Thickness 1105 feet. 



1. Group A. Blue clays, alternating with grey sandstones, which 

 contain locally large quantities of petroleum. Fossils are scarce, 

 but chiefly marine, with rolled fragments of bones and some teeth 

 of land animals. Thickness not less than 1000 feet. 



The author points out that this series exhibits a gradation from 

 a littoral marine formation to fresh-water deposits ; that the verte- 

 brate remains belong to a fauna nearly identical with that of the 

 Sewaliks ; " that Group C (probably inclusive of Group B) must be 

 of Upper Miocene, if not Pliocene, age " ; and that the ferruginous 

 conglomerate, containing the chipped flints, is therefore either lowest 

 (earliest) Pliocene, or uppermost (latest) Miocene. 



The well-known ossiferous Sewalik strata are regarded as Lower 

 Pliocene by Lydekker ; but Upper Miocene by Gaudry, Boyd- 

 Dawkins, and others. 



There were about a dozen specimens of worked flints found in 

 the ferruginous conglomerate by Dr. Noetling, whose attention was 

 drawn to them by one in particular, 45 millemetres long and 20 wide 

 (illustrated by figs. 1, la, 16), which was partly imbedded in the rock 

 close to a fine lower molar of Hippotherium (fig. 6) ; four of the 

 other flint specimens are shown in figs. 2, 3, 4, 6, in various aspects. 

 These latter are more or less triangular flakes, about 25 millemetres 

 long ; and some specimens which seem to be ordinary ridge-flakes, 

 as much as 40 mm. in length. 



It is not clear why Dr. Noetling inserted a note of interrogation 

 after the word " chipped " in the title of his paper. The specimen 

 (fig. 1), which he terms "a rectangular flake," has been very 

 definitely dressed ; and the other smaller flakes have evidently been 

 struck off" larger flints, and probably manipulated so as to have a 

 point and one or more sharp edges. The bettermost specimen 

 (fig. 1) is ridged on each face, rounded at one end, truncate at the 

 other, and has its edges almost parallel and sharp. One ridge-face 

 retains a narrow strip of its original flat surface ; and the other is 

 sharply defined by nearly symmetrical flakings sloping up from the 

 edges and meeting in a line along the middle. One edge of the 

 implement is somewhat concave, either by irregular flaking, or 

 subsequent breakage, on the face (fig. la) retaining a strip of the 

 former plane surface. 



It is apparent, therefore, that worked flints have been found by an 

 experienced Geological Surveyor in India in a stratum of either 

 Upper Miocene or Lower Pliocene age. In the title of his paper 

 Dr. Noetling refers it to the " Upper Miocene."
