not the outer surface of this shell, which is more carboniferous 
in its appearance than any other of the Brachiopods above 
described. 
I must not omit the notice the large Spirifer Rajah , from 
Spiti Pass. It is possibly S. Keilhaviij * but that is uncertain. 
What is certain is, that it belongs to a carboniferous group of 
species, and is probably more allied to the S. duplicicosta, 
Phillips, than might, at first sight, be imagined. I have 
described it, and it is figured in the woodcut above (p. 53). 
But it is one of the fossils of the Sipiti Pass, and I have 
merely quoted the other Triassic forms from that district, 
leaving their description to Professor Oldham and his corps 
of scientific men. 
CORALS. 
A few lamelliferous corals were found in the Spiti Pass, 
among Ammonites evidently of this formation. 
What is singular is, that scarcely one of the Triassic fossils 
obtained from the Spiti district, and brought home last year 
by Professor Oldham, correspond with those of the Niti Pass, 
though 100 miles nearer to the Alps. I could hardly identify 
a single form with Hauer’s figures, and I am compelled to the 
belief that we have a different and older group, possibly of 
Bunter Sandstone Age, in the Spiti Valley. 
It will crown all these researches if the Indian geologists 
should find the shallow and deep water deposits of the Permian 
Age. It cannot but be that there is a rich harvest, yet un¬ 
reaped, from this transition period.
