CRICK: JURASSIC AMMONITES FROM INDIA. 289 
figures having been drawn from a portion of the specimen after some of 
the matrix had been removed. This view is further supported by the 
copy of fig. 2b in the ‘English’ set of the plates already alluded to, 
the line indicating the original extent of the matrix as seen in Gray’s 
figure being clearly indicated, as well as the small irregularly-shaped 
patch from which the test has been chipped off. The suture-line on 
the same plate numbered in the ‘Indian’ set of plates 26, and in the 
‘English’ set 2d, does not, as we have already stated, belong to 
A. tenuistriatus,' but to Wallichii, and should have been numbered 1c. 
As we have already pointed out elsewhere,’ Blanford misquotes Gray’s 
species as ‘‘ Amm. tenuisulcatus’’; but he corrects the mistake in the 
list of ‘ Errata’ given on p 112. 
Although the dimensions of the specimen cannot be given with 
absolute certainty, the fossil has been cleared enough to enable these 
measurements to be indicated approximately. They are as follows: 
diameter of the shell, 84 mm.; height of outer whorl, about 32°5 mm. ; 
thickness of outer whorl, probably about 27 mm.; width of umbilicus, 
about 31mm. One of the inner whorls is also revealed; it has a 
diameter of 14mm.; the height of the whorl at this diameter being 
4:1 mm., and the width on the umbilicus 5*2 mm. 
The conclusions arrived at in the preceding note may be expressed 
as follows :—
