There are two pale yellow marginal stripes which vanish 
before reaching the head, and end rather abruptly behind four 
or five rings in advance of the rings whose margins are pro- 
duced into the lobes above described. 
The median area is most often a dull yellowish brown, con- 
siderably lighter than the lateral areas. In some cases (figs. 
1, 6, 7) the median area inclines rather to a reddish hue, the 
lateral areas being a deeper and richer shade of the same 
colour. The lateral areas and the somewhat lighter ventral 
surface are generally sprinkled with fine specks of dark brown. 
Sometimes, as seen in fig. 5, a feeble tinge of olive is per- 
ceptible. The anterior border of the cephalic lobe has a 
smoky hue which frequently extends to the entire head and 
anterior portion of the body. The acetabulum is a very pale 
green or olive above, and smoky brown or olive brown below. 
The clitellum is sometimes marked by a deeper shade than 
the rest of the body (fig. 5). 
The ground colour of the Singhalese species (figs. 8, 9) is a 
rich reddish brown flecked with dark brown, more profusely 
above than below. The head and posterior sucker show the 
smoky hue seen in the Japanese species. There are no dark 
stripes, and, as a rule, no indications of a median area. There 
are two marginal stripes and one median, all of which are a 
bright lemon yellow. 
Among several hundred specimens I found two or three in 
which a lighted median area was more or less imperfectly 
indicated. In all other particulars this species agrees com- 
pletely with Hemadipsa japonica. 
Habitat.—So far as could be ascertained, the Japanese 
Land Leech is confined to mountain slopes and ravines, never 
descending into the low plains, for which reason the Japanese 
call it the Mountain Leech (“ Yamabiru:” yama, mountain, 
and hiru leech). Specimens were collected by Mr. Jijima 
from Akihazan, a mountain about 4000 feet high, situated 
near the centre of the province of Totomi (Enshia), by Mr. 
Sasaki on mountains in the provinces of Mino and Iga, 
between 34° and 36° lat., and by myself on a mountain in
