hind end of the body, and were then continued as one stripe to 
the edge of the acetabulum. The same stripes coalesced also 
anteriorly. 
The ground-colour of the dorsal surface was a dull olivaceous 
green; the ventral sarface was pea green thickly flecked with 
black. The yellow margins were bounded on the ventral side 
by a broad black stripe, the inner edge of which was quite 
uneven. 
The dorsal half of the papillate rings bears eight segmental 
papille ; the ventral half six. On the dorsal side (Pl. XX, 
figs. 47, 49) we see two median rows of papille (m.), 
located on the following annuli—2, 3, 5, 8, 11, 14, 19, 24, 29, 
34, 39, 44, 49, 54, 59, 64, 69, 74, 79, 84, 89, 94, 97, 99, 101; 
two inner lateral rows (#.), beginning on the eleventh annulus, 
and following the line of the lateral stripes to the posterior end 
of the body; two outer lateral rows (ol.), near the outer 
edge of the lateral areas of colour, beginning as far forward as 
the fifth annulus and traceable to the 101lst annulus; and 
two marginal rows (mg.), located in the narrow latero- 
marginal yellow stripe. On the ventral side (fig. 48) we 
find two marginal rows (mg.), located in the inner edge 
of. the yellow margins of the body; two lateral rows 
(1.), just imside the black stripes; and two median rows 
(m.), separated from each other by a little less than one third 
the width of the body. 
The median rows of the dorsal side exhibit serial relation- 
ship with the first pair of eyes; while the inner lateral rows, 
which are larger and more conspicuous than the others, show a 
similar relationship with the remaining pairs of eyes. 
Counting from the first pair of eyes to the anus, there are 
twenty-six somites, of which six at the anterior and four 
at the posterior end are abbreviated, leaving sixteen full 
somites between the first and last pair of nephridial pores. 
The total number of annuli is 101, of which thirteen belong to 
the first six somites, eighty to the sixteen full somites, and 
eight to the last four somites. The Ist and 2nd somites are 
each represented by a single ring; the 3rd by two rings; the
