THE INDIAN MUSEUM: 1814—1914. 
(wherever possible) trivial names with which all are in¬ 
scribed. 
The research collection of marine invertebrates is stored, 
together with those of the reptiles and batrachians, in two 
large galleries adjacent to the library upstairs, with the ex¬ 
ception of a few of the smaller groups kept in the superin¬ 
tendent’s laboratory. 
The other zoological gallery on the ground-floor is much 
smaller, occupying only 1760 square feet; it contains insects, 
arachnids, myriapods and several other smaller groups. 
Wood-Mason and de Niceville devoted particular attention 
to this gallery and devised, together or separately, some 
simple and ingenious methods of arrangement. One of these 
is shown in the illustration opposite, in which a photo¬ 
graph of the exhibit illustrating the life-history of a com¬ 
mon tea-pest is reproduced. Within the last few years cases 
illustrating such problems as variation, mimicry, sexual 
dimorphism, the comparative anatomy of insects and their 
allies, have been prepared or revised and are now being set up 
while the various groups of arachnids and myriapods have 
been entirely rearranged with fresh descriptive labels. 
Only a very small proportion of the entomological col¬ 
lection is exhibited to the public, all specimens that could 
not be readily replaced being preserved on the first storey in an 
entomological room, or rather in two rooms, to which only 
serious students are admitted. 
Upstairs, the vertebrates are displayed in two large and 
two small galleries, which correspond roughly in size with 
the large Invertebrate Gallery and the Insect Gallery respec¬ 
tively. The mammals are divided, without pedantry, into 
large mammals” and ‘'small mammals,” the former being 
shown in a large gallery and the latter in a small one. The 
arrangement is convenient, and much less unscientific than 
it might seem at first sight to be; under the heading of 
" small mammals” are included the monotremes, marsupials, 
edentates, insectivores, rodents and bats; the remaining 
groups being shown in the large gallery. 
In the arrangement of all of the public galleries of zoo¬ 
logy in the Museum it has been accepted as a principle that
