« This is the common white ant of Sind, at any rate of lower 
Sind; and is found all around Karachi on the very small and low 
hills and on the mud flats. 
These termites throw up small conical heaps of earth pellets at 
short intervals everywhere in the vicinity of their nests along the 
radiating passages, which are generally within 4 inches of the 
ground surface, but have often a supplementary passage 6 inches 
below and always immediately beneath the superficial one. 
The main nest consists of horizontal, flat, low chambers, one 
above the other, but by no means straight above eachother; and 
there are often {wo or three such chambers, one leading off the 
other, at the same level. 
The total depth of a nest or colony may be 6 feet; I dug one out 
of that depth. The passages are very ofien of great length — I dug 
one up 20 yards in length; — and at intervals along the passages 
there are branch passages, generally leading up to the surface 
where the mounds of earth (never more than 6 or 8 inches in 
height) are thrown up, with a solid tube in the centre : which tube 
is generally quite closed. All the inside of the chambers is lined 
with a chocolate coloured rough looking substance. » 
«The colony I dug up was situated this time in a sand-stone 
hillock, — composed of slabs or strala of sand-stone alternating 
more or less irregularly, with a sort of sandy clay, — near the sea 
and on the side of a wide expanse of sand hills overgrown with 
species of Sueda (maritima is one of them), wild Heliotropum, 
some coarse grasses and a species of Lotus, many Indigofera, some 
Amaranthaceæ, Zygophyllaceæ, etc. 
The colony went down nearly 4 feet into the stone, mainly by 
passages of an oval section (as usual), through the soft parts; but
