Land leeches are mostly tropical, living in the area defined by the parallels 

 40° N. and 40° S. of the Equator, for they appear to prefer a warm, moist 

 climate. In the Himalayas they ascend to a height of n,ooo feet; but in 

 Ceylon they diminish in numbers above 4,000 feet. They are to be found 

 in Ceylon, India, Java, Sumatra, Luzon, Mindanao, Pelew Islands, Japan, 

 New Guinea, Celebes, New South Wales, Queensland, and the southern 

 provinces of Chili and Trinidad. They live under damp leaves and loose 

 rubbish, and appear when the air is disturbed by the approach of man or 

 beast, and so quickly do they rush to the attack that they have earned the 

 name of the ' jumping leech.' As a rule they bite gently, but make a deep 

 wound, the scar of which may take months to disappear. They fill them- 

 selves with blood in about thirty minutes, and then drop off.
