NOTE ON DR. J. E. GRAY’S TYPE-SPECIMENS OF JURASSIC 
AMMONITES FROM INDIA. 
By G. C. Cricx, F.G.S., 
Of the British Museum (Natural History). 
Read 12th December, 1902. 
In the first volume of his work entitled ‘‘ Illustrations of Indian 
Zoology; chiefly selected from the collection of Major-General 
Hardwicke,” published in 1830-32, J. E. Gray gave, on plate c, four 
figures of three species of Ammonites which he named A. Nepaulensis 
(figs. 1 and 2), A. Wallichi (fig. 3), and A. tenuistriata (fig. 4). 
According to the legend on the plate, which is dated 1829, they all 
came from ‘‘Sulgranees, Nepaul.’’ The species were not described. 
Of these specimens three, viz., the originals of figs. 1, 3, and 4, are 
in the British Museum collection, and bear respectively the register 
numbers C. 5,052, C. 5,041, and C. 5,051; the other specimen, the 
original of fig. 2, we have not been able to identify. 
Although the conclusions respecting 4A. Wallichi and A. tenuistriata 
recorded below have already been briefly stated elsewhere,! the 
published figures of these specimens differ so much that a fuller 
explanation seems to be necessary. 
1. Ammonires Nepavtensis, Gray. 
Although some of the matrix has been removed since Gray’s figure 
was drawn, there is abundant evidence that the specimen in the British 
Museum coliection bearing the register number C. 5,052 is the original 
of Gray’s fig. 1.2. The drawing is of the natural size, but is reversed ; 
it shows that the fossil is partially enclosed in a nodule, a portion 
of only one side of the outer whorl being exposed. Since Gray’s 
figure was drawn, an attempt has been made to clear the matrix from 
the rest of the outer whorl; the commencement cf the outer whorl 
has been successfully cleared, but the greater part of the whorl that 
was covered by matrix has been injured during the operation. There 
is, however, no difficulty whatever in recognizing the fossil as the 
original of Gray’s fig. 1.
