﻿612 MR. L. V. DALTOIs' ON THE [^OV. I908, 



at angles of 69° and more, the crest of this anticline being marked 

 by hot springs and mud-voleanos. 



From near the crest in this locality an impure ferruginous 

 limestone was obtained, full of shells of Turritella sp. 3. 



Dips of 20° to 30° in a north-easterly direction were found 

 north-north-west of Thabyemyoung ; and 2 miles west-south-west of 

 Myegya (long. 94° 45' E., Iat.l9° 53' IS".), south of the Upper Burma 

 boundary, a calcareous sandstone was found with Venus granosa, 

 J. de C. Sow., and Tellina (7). 



Across the boundary, in the Minbu district, the same north- 

 eastward dipping beds yielded the following species of fossils near 

 the village of Magyisan (long. 94° 42' E., lat. 19° 57' N.) :— 



(«) 1 mile south-east of Magyisan, light-blue clay with : 



Dolium sp. 



Pleurotoma Stoppanii (?) Desh. 



Oferculina Hardiei (?) D'A. & H. 



Paracyathus sp. 



Corhula harpa, D'A. & H. 



(5) 1 mile south of Magyisan : 

 Ampullina grossa, var. ohlonga, Desh. 



(c) Yengadin choung, 2 miles south by east from Magyisan : 



Nummuliies sp. Cerithmm sp. (cf. Vicarya Ver- 



neuili, D'Ai'ch.). 

 Conus sp. 

 Isatica sp., cf. iV! ohscura, J. de 0. And fragments of a very large 



Sow. CerithiuTii. 



Area manensis, sp. nov 

 Ampullina spherica (?) Desh. 



Some 4 J miles north-west of Magyisan, near the village of 

 Kyetubok, in the choung of that name, a bed of very shelly impure 

 nummulitic limestone was found, dipping 60° to N. 60° E. — the 

 rocks above this limestone for some distance having the same strike 

 and dip, but containingno nummulites. There is no doubt that this 

 limestone, here about 25 feet thick, is identical with that described 

 by Theobald as marking the top of the Eocene in Lower Burma. 

 The fossils determined from this bed were : — 



l\umomdites Beaumonti (?) 



D'A. & H. 

 Glycimeris sp. 

 Thracia sp. 



Cardium amhiguum, J. de C. Sow. 

 Ficula Theohaldi, Noetl. 

 Oliva sp. 



Descending in the series westTvards, I met with two fossiliferous 

 horizons : one being a thin white limestone, made up of small 

 globular bodies of Hydrozoan affinities and of various foraminifera, 

 including Operculina canalifera^ D'Arch., half a mile north-west of 

 Kyetubok ; and the other, at a lower point in the series in the Kye- 

 tubok choung, yielded a worn specimen of Ampullina jDonderosa, 

 Desh. After striking the Minbu-Xgape road north-west of the 

 last-named localities, blocks of arenaceous limestone were found 

 full of Ampullina grossa, Desh., var. ohlonga. These come appa- 

 rently from an horizon near that already cited as yielding this species 

 south of Magyisan.
