legs of other Arachnids are modified so as to form teelers, though not 
such extraordinarily long and slender ones. 
In the Kandy District I have only met with one species of whip- 
scorpion (Labochirus proboscideus), a creature of about the size of 
the small brown scorpions often seen about the verandahs of 
bungalows, but black and of a stouter build ; a much larger species 
(Thelyphonus sepiaris) is, however, recorded from the low-country. 
The small species is to be found under stones and logs of decaying 
wood in the neighbourhood of water-courses—but not on marshy 
ground—and in other parts of the jungle when the ground is 
thoroughly moistened by the rains. This species digs a burrow

for itself beneath the stones under which it lives; and when its 
surroundings become dry, it appears to retire underground and 
remain there ; but on this point also further evidence is wanted. 
Moreover, males (with long arms) appear to be three or four times 
as common as females (with shorter arms), a condition which again 
needs explaining.* Mr. Green tells me that the larger low-country 

* Further observations have proved this statement to be erroneous, or at 
least that it only holds good at a definite season of the year. My first 
specimens (all males) were obtained on May 5, before the break of the 
monsoon. The first female was obtained on July 20, a day or two after 
the commencement of the second period of wet weather this season. from 
that date to the present time—August 3—females have been much more 
and males much less frequently found. As the total number of specimens 
found, however, is little more than a dozen, and as my observations have 
been confined to a visit of three months, it is impossible to state with 
certainty that this apparent seasonal appearance of the sexes separately is an 
actual fact without further evidence; but if so, it is a very remarkable one.
