246 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
inferior one being the broadest and undivided (divided by a narrow 
white space on the propodites of the legs of the second pair) ; 
the two superior are narrow and separated by a broad white 
space, which is even broader than the white space between the 
middle line and the inferior one. These lines are continued, in 
the same manner, on the outer surface of the carpopodite, mero- 
podite, and ischiopodite ; whereas those of the inner surface are 
little distinct. The inferior line on the outer surface of the pro- 
podites of the legs of the third pair appears, however, to be 
constantly divided into two lines on the outer surface of the 
following joints, so that the outer surface of the carpopodites is 
marked with four narrow red lines, of which the two superior 
are separated from one another by the broadest white interspace 
and with a fifth red line near the under margin. The legs of 
the fourth pair also present some red lines. 
In very young specimens the two red lines which are found 
on the outer and on the inner surfaces of the dactylopodite are 
not divided into secondary lines on the other joints, but are con- 
tinued on them undivided.
