CRICK : JURASSIC AMMONITES FROM INDIA. 287 
portion of the whorl, which is the portion on the right in fig. 1a, has 
been restored. That the whorl has been restored can be readily seen ; 
the sculpture on the last half of the outer whorl has evidently been 
copied, though not very correctly, from the actual specimen, and also 
the few fine ribs at the commencement of the outer whorl; but the 
ribbing of the intervening portion is obviously so inconsistent with 
the rest that it cannot possibly have been copied from an actual 
example; this, in fact, is the restored portion. Further, the appearance 
of the last three ribs at the anterior part of the specimen corresponds 
exactly to the exserted portion of these ribs in Gray’s type-specimen. 
The width of the umbilicus is more nearly correctly represented in 
Gray’s figure; this is relatively far too wide in Blanford’s figure. 
The ribbing also is much too irregularly represented in Blanford’s 
figure. 
Blanford’s fig. 16, if taken from this specimen, is perfectly imaginary 
so far as the right-hand portion of the figure is concerned, for this 
side of the fossil is completely obscured by matrix. Blanford admits 
that the figures are incorrect, for he says ‘‘the overlap of the whorl 
is considerably greater than is represented in the figures, Plate xiv, 
and the aperture or section of the whorl, longer and more compressed- 
ovate than in fig. 14.’ We think, however, it is clear that the 
original of Gray’s fig. 1 is the original also of Blanford’s pl. xiv, 
figs. la, 6. This is the fossil in the British Museum collection bearing 
the register number C. 5,052. The dimensions of the exserted portion 
of the fossil, as nearly as can be measured, are: diameter of shell, 
101 mm. ; height of outer whorl, 46°5 mm.; thickness of outer whorl, 
estimated at about 37 mm.; width of umbilicus, 23 mm. 
2. Ammonites WaLticutil, Gray. 
Gray’s type-specimen is in the Brit. Mus. collection (No. C. 5,041).? 
There can be no doubt about the identification of the specimen, because 
Gray’s figure, drawn of the natural size though reversed, represents 
the injured portion of the outer whorl, and also indicates the small 
shell imbedded in the matrix at the anterior end of the fossil; the 
diameter is fairly accurately represented, but the width of the 
umbilicus is a little too narrow. The dimensions of the specimen 
are as follows: diameter of shell, 94 mm. ; height of outer whorl, 
33°5mm.; thickness of outer whorl, 31°5mm.; width of umbilicus, 
o7 mm. 
H. F. Blanford, in J. W. Salter & H. F. Blanford’s “ Paleontology 
of Niti in the Northern Himalaya,” 1865, figured this species (pl. xv, 
figs. la and 6), and a comparison of his figures with Gray’s type— 
the form of the anterior end and the presence there of a small shell 
imbedded in the matrix—shows conclusively that they must have 
been drawn from that fossil. The eroded portion of the whorl has, 
however, been restored, both in figs. la and 6. The dimensions of
