CARNIC STAGE. 
87 
The topmost portion of the Daonella limestone is probably of carnic 
age. 
On the top of the Daonella limestone — 145 feet above the upper limit 
of the Daonella shales in the section of Lilang — - a black limestone 
alternating with shales, 25 feet in thickness, has been observed by 
A. V. Krafl't dividing the otherwise homogeneous mass of limestone. 
This is the bed of Jo'innites thamimensis Dien. The upper division of the 
mass of dark splintery limestone, following abave the bed of Joannites 
thanamensis, has yielded Halohia cf. comata Bittn., a species typical 
of the julic substage in the Himalayas.^ 
Above the " Halobia limestone " grey, earthy shales follow, in which 
grey, shaly limestones of various thickness are intercalated. About 
260 feet above the base of tliis series of " grey beds " a thin-bedded, 
shaly limestone of 20 feet in thickness has been noticed. 
Fossils have been discovered in two horizons. Almost immediatelj'' 
above the Halobia limestone the shales contain a band of black 
concretions, which enclose numerous ammonites. The following species 
have been determined by Diener — 
Trachyceras sp. ind. aff. Ariae Mojs. 
sp. ind. (group of acanthica). 
Carnites floridus Wulf. 
,, cf. nodiger Dien. 
Joannites cymbiformis Wulf. 
Monophyllites sp. ind. aff. Simonyi Hauer. 
The second fossiliferous horizon occurs about 300 feet above the 
base and about 40 feet above the thin-bedded limestone referred to above. 
Fossils are known from two localities, N. N. W. of Lilang and N. W. of 
Muth. There is only one single species of ammonite among them, 
and this is so poorly preserved that an exact determination is impossible. 
It has been referred to the genus Paratropites Mojs. provisionally by 
Diener {I. c, p. 149). But the fauna of both localities is rich in braohio- 
pods and bivalves, which belong to tlie following species : — 
Rhynchonella laticana Bittn. 
„ laucana var. lilangensis Bittn.
