made by Mr. Crawfurd in 1826, having carefully gone over the 
whole series in the same museum. The characters of the 
Nerbudda specimens were familiar to me through the collections 
taken to England by Mr. Charles Fraser ; and Dr. Spilsbury was 
at hand to point out all which he had presented to the Asiatic 
Society, that were still in existence. 
The Perim Island fossils, are usually imbedded in a yellow 
marly conglomerate, very different from any thing met with 
among the Sewalik or Ava Fossils. Where the matrix has been 
washed off, the specimens have usually more or less of marine, 
encrustation upon them. These characters, readily distinguish 
them from the Ava, Sewalik Hills, or Nerbudda, fossils : and no 
specimen probably has been introduced into the Perim portion 
of the Catalogue, that did not come from the Island or adjoining 
parts of the Gulf of Cambay. No elephants' molars were found 
among them although Capt. Fulljames mentions “the teeth of 
Mammoth" as having been transmitted by him to the Asiatic 
Society. (Journ. A. S. Yol. Y. p. 200.) 
The Nerbudda fossils are readily distinguished from those of 
Ava and the Sewalik Hills by their mineral characters ; but this 
help fails in discriminating them from the fossils of the Jumna 
Alluvium. Some specimens have been conjecturally introduced 
into the Nerbudda Catalogue although not recognized by Dr. 
Spilsbury, the only Nerbudda Donor. This circumstance throws 
great doubt on the place assigned to them. Are they from the 
J umna, or of the Culpee specimens presented by Dr. Leslie ?* 
The great mass of the Sewalik Hill collections were separated 
without much hesitation. 
The most unsatisfactory part of the Catalogue is what regards, 
the Ava collection. The greater portion of it was presented by 
Col. Burney, and the rough list by James Prinsep, printed in 
the proceedings (Vol. III. p. 365 J. A. S.) enumerates the fol- 
lowing :
