A CONSIDERABLE number of Crocodilian scutes, collected by the 
late Marchioness of Hastings at Hordwell, are now deposited in the 
Museum of Practical Geology. These scutes may be divided into 
two great groups-—1, angulated, and 2, fat. The former are distin- 
guished by the angle, open downwards, or towards the ventral side, 
which their lateral halves make with one another, and by the raising 
up of their outer surfaces into a more or less prominent longitudinal 
ridge along the line of angulation. The under surfaces of these 
scutes are more or less concave from side to side, and convex from 
before backwards. The flat scutes, on the other hand, are flat, or at 
most a little convex from side to side above, and slightly concave in 
the same direction below. There is a singular disproportion between 
the two kind of scutes, for, out of some hundreds, only two or three 
incomplete specimens exhibit the peculiarities of the flat scutes. 
The angulated scutes (figs. I-7) may be subdivided into two kinds, 
those with, and those without, an anterior articular facet, the former 
being the more numerous. 
The angulated scutes provided with an articular facet are in their 
general characters so like those which I have described in my paper 
on Stagonolepis (Quarterly Journal of the Geological Society, 1859), 
that I will only refer to their special characteristics. There are two 
kinds of them, the one set much, the other very little bent down at
