DIENER : TRIAS OF tHE HIMALAYAS. 
division contains Daonella indica Bittn., and, in its lower part, als 
Daonella Lommeli, whereas in the upper region Halobia cf. comata Bittn., 
a species of the carnic group of rugosoe, has been found. 
A. V. Krafit, who designated the lower division as " Daonella lime- 
stone " and the upper as " Halobia limestone, " gives the following 
sequence of beds between the Upper Muschelkalk, and the grey shales 
with Joanites cymhiformis ^ : — 
4. Hard, black, splintery limestone, somewhat bituminous, 
with calcite veins, weathering greyish brown, inter- 
calated with shaly limestones in layers of one to three 
feet contaimng Halobia cf. comata Bittn., and H. fasci- 
gera Bittn Ill ft. 
3. Black limestones, intercalated with shales containing 
Joannites thanamensis Dien. . . . . . 25 ft. 
2. Hard black limestones, as 4 with Daonella indica Bittn. 
Daonella Lommeli occurs in the lower division, but not 
higher up tlian to the upper third of this group . . 145 ft. 
1. Series of thin-bedded black shales and limestones (Dao- 
nella shares) with -Daonella Indica Bittn. and D. 
Lommelli Wissm. ..... . 160 ft. 
Series No. 2 corresponds to A. v. Krafft's " Daonella limestone.'^ 
It contains a fauna consisting of the following species : — 
Traumatocrinus sp. ind. 
Daonella Lommeli Wissm. 
„ indica Bittn. 
,, sf. ind. aff. CassiancB Mojs. 
Rhynchonella cf. rimkinemis Bittn. 
Phloioceras deliciosum Dien. 
Styrites lilamjensis Dien. [ 
Celtites trujonalis Dien. 
perauritus Dien. 
Ritnkinites nitiensis Mojs. 
Monofhyllites cf. ivengensis Klipst. 
Joannites cf. Klipsteini Mojs. 
Kossmati Dien. 
In this fauna Wengeu and St. Cassian types are associated so closely 
that both equivalents of the highest ladinic and of the lowest carnic 
beds of the Mediterranean regions seem to be represented in the Dao- 
nella limestone of Spiti.
