tlie spoto to investigating these statements, hut he could find no tiace 
of such fossils ; nor could he reconcile M. D’Archiac s statements 
with Major Vicary’s published account. Possibly the explanation of 
the difference is this. Major Vicary does mention fossil bones at 
and near to Subathoo, he says, “ Saurian remains are, however, plenti- 
ful ; I am not so sure with respect to mammalian remains, hut, as the 
specimens are in good hands, I hope soon to settle that point. 
These remains, however, he in every case describes as occuning in 
blue or red shales alternating with or underlying Nummulitic strata. 
Without in the least questioning Professor Owen’s skill in identify- 
ing genera from obscure remains, Mr. Medlicott was forced to think 
Major Vicary far too experienced and too intelligent a collector, to 
have failed in recognizing as mammalian such abundant remains as 
are mentioned by M. D’Archiac— “ Elephas, equus, bos, cervus, 
&c., des debris de dent d’un elephant mastodontoide,” and other 
similar statements. A clue to the explanation is to be found m 
M. D’Archiac’s own words — that the sands, gravels aud conglomeiates 
with hones of large mammalia rest quite conformably on the Num- 
mulitic beds near Subathoo, (p. 17G.) Now there is not even an allu- 
sion to such rocks by Major Vicary ; on the contrary he says, the 
blue shale, on which the quarter-guard of Subathoo stands, contains 
fossil bones in abundance,” and so in other cases. In truth, there 
are no such rocks at Subathoo, as those spoken of by M. D’Archiac. 
Such rocks are unquestionably the common habitat of Siwalik iossils, 
and it is not improbable that, in consequence of original deficient 
labelling of specimens and possibly of subsequent intermingling, 01 , 
in consequence of a misunderstanding of written or verbal commu- 
nications, some true Siwalik fossils were mistaken as coming irom 
near Subathoo. 
Mr. Medlicott’s own researches, extending over a direct distance 
of more than two hundred and fifty miles, from the parallel of Namee 
Tal to beyond the Sutlej, led him to expand considerably the series 
of rocks which were known to occur within these limits. Ibis, lor 
the present, could he most conveniently done under the two groups 
already known, viz. the Nummulitic and the Siwalik. Of these 
groups, the latter is continuous beyond the limits of the area examined ; 
the former are much more irregular. The upper Nummulitic group
