HAYDEN: GEOLOGY OF SPITI. 
among them, however, are some bivalves which were determined by 
the late Dr. A, Bittner as— 
Lima cf. atistriaca, Bittner. ; 
Daonella cf. styriaca, Mojs. ; and 
Halobia cf. superba, Mojs. 
In Europe, Lima austriaca occurs in the Opponitz limestone and 
Daotielln ^tyfiaca and Halobia superba tn the carnic beds of Aussee.' 
The following sequence is found in Spiti above the Tropites 
beds : — 
5. Black, splintery and earthy limestone and dolomite; with 
Megalodon ladakliensis, Bittner. 
Dicerocardium himalayense, Stol. 
Lima cumaunica, Bittner. 
„ serraticosta, Bittner. 
(?) Spifigera noetlingi, Bittner. 
4. White and brown quartzite, with black shales and grey limestone ; 
with 300 ft. 
Spirigera n. sp. 
Aulacothyris joharensis, Bittner. 
Lima cumaunica, Bittner. 
Spiriferina griesbachi, Bittner. 
3. Brown-weathering shale (calcareous and micaceous) and chaly 
limestone, A-ith some sandstone ; with 300 ft. 
Spiriferina griesbachi, Bittner. 
Rhynchonella bambanagensis, Bittner. 
Spirigera dieneri, Bittner. 
Aulacotliyrts joharensis, Bittner. 
Monofis salinaria, Bronn. 
Anodontophora griesbachi, Bittner.

I. Brown-weathering shale, with shaly limestone and sandstone; 
with 500 ft. 
P aratibetites cf. iornquisti, Mojs. 
yuvavites, cf. ehrlichi, Mojs. 
Hauerites n. sp. ind. 
Above the dolomitic limestone a rapid change takes place in the 
lithological character of the beds. The compact limestones give place
