TASM A NIAN BIOLOGICAL SURVE Y. 
The Report and Balance Sheet for this Survey 
has just been issued for the year ending Dec. 31,1957. 
It will be remembered that the Survey commenced 
operations in July last and during the six months 
under review excellent progress has been made. Certain 
papers are shortly to be published in the Proceedings 
of the Royal Society dealing with research work carried 
out by members. More collectors are needed, and full 
particulars may be obtained from the Secretary at the 
Museum. 
CAVE SPIDERS AND CAVE INSECTS . 
Cave animals are of particular interest, their 
eyes are more or less degenerate and they often have 
no ears and no sound organs. To compensate for the 
loss of these they possess enormous antennae or feelers, 
and other sense organs are greatly developed. The 
hairs on the body and limbs of many cave animals in¬ 
cluding the spiders no doubt help to warn them of dan¬ 
ger, they are extremely sensitive to slight air cur¬ 
rents. The Biological Survey is particularly keen to 
obtain specimens of cave inseots and spiders.
