It was intended to have serially arranged the specimens in the 
order of their affinities : but this was found to be impracticable 
as there was no space available to distribute them in a rough 
preliminary arrangement. In consequence, bones belonging to 
one species, instead of following in consecutive numbers are 
distributed irregularly throughout. In this view, the Catalogue 
can only be regarded as a first effort to serve the preparation of 
a more perfect Catalogue hereafter. It has assumed the 
character of a descriptive Catalogue instead of being merely a 
numerical and nominal one in consequence of the great number 
of new or important specimens that required description. 
Each geographical series has its own numbers, thus the 
Ava specimens are marked

The discriminating numbers have been attached both by 
paper labels covered over with mastic varnish, and with white 
paint on a black ground, so as to secure every chance of dura- 
bility. 
During the progress of the Catalogue a party of stone-cutters 
were employed in chiselling the specimens, and clearing them of 
matrix, most of the specimens in the collection have in this 
manner been brought fully out ; where they required it. 
The greater part of the Catalogue is in the hand-writing of 
my friend Dr. Henry Walker: and I will say no more of his 
services, than that without his most efficient aid, this Catalogue
