Lapt6I tlie sliales overlie limestones, and they form a trough, which has a north- 
north-west sonth-sonth-east strike. They extend southward as far as the 
halting-place at the foot of the Kingrii ghat. 
“ The different formations of the triassic pei’iod are very poorly represented 
Triassic fossils. collection, hut nevertheless the materials are suffi¬ 
cient to state with all certainty the existence of these 
formations. To the upper Trias very probably belong some hard, flaggy, dark- 
grey limestones, with millions of fragmentary shells imbedded. However, only 
on the weather-worn surfaces some species can he recognised, it being impossible 
to get anything out of the interior of the rock. I am able to recognise one 
species of Monotis, and two species of Pectens, on thi’ee different rock specimens. 
The only species determinable, however, is Bhynchonella austriaca, Suess. 
“ There are yet two other divisions of the Trias indicated by fossils in two 
different kinds of rock. The one is represented by two fragments of Ammonites 
of the group of Ammonites semipartitus. They are preserved as black nodules 
in a hard, dark-grey, silky, slaty shale, which very likely belongs to the ‘ Muschol- 
kalk ’ formation. The other division of the Trias is indicated by a small 
specimen of a badly preserved Ceratite, somewhat like some species of the Salt 
Range, and thus possibly out of some ‘ Bunter Sandstein ’ beds. The rock in 
which it is preserved is a hard, red, crypto-crystalline limestone. 
“ These few fossils, though badly preserved, and specifically not determinable, 
yet show beyond a doubt the existence of a rather complicated group of triassic 
rocks.” 
There are two geographical zones of this and the underlying series, one 
being south of Laptel, and the other north of it, in the du'oetion of KanchSgo. 
“ The next older formations, permian and carboniferous, are represented in 
the collection by a somewhat better suite of fossils. The 
most fossiliferous bed is a white limestone with a great 
number of fragments of crinoid-stems, and the following 
determinable species:— 
“ Terebratula Imnalayensis, Dav. 
“ „ suhvescicularis, Dav. 
“ „ sp. nov. ? 
“ Athyris roissyi, L’Ev. 
“ Spirifor cf. glaber, Martin. 
“ OameropJioria, sp. nm. ? 
“ Produatus semireticulatus, Martin. 
“ „ sp. 
“ Pactrynium sp. 
“ Gyatlioplmjllum sp. 
“ It is very interesting to trace how much this fauna resembles that of the 
lower carboniferous limestone in the Salt Range; and even the preservation of the 
specimens is such, that they could be mistaken as coming from the Salt Range. 
Produchis semireticulatus occurs of its typical size, whilst the small form from 
Spiti, which is found also here, and quoted by me as “ Prodiidus, sp.,” is very 
likely a different sjjecies. The latter, however, has been also obtained, 
though rarely, from the Salt Range.
