of papillae, those of each pair corresponding with, but extending a 
little way on each side of the inner couples of setae, and by fusion 
with the modified intermediate portion giving rise to ridges, in 
worms with girdles the middle one the most conspicuous, the 
papillae carrying the male pores relatively more developed. In 
D. armifera there are no papillae on xtHi and xix, but the ventral 
surface of these segments is raised for a space extending out- 
wai-ds on each side about as far or a little beyond the first row 
of setae, whereas on xviii the whole ventral surface is modified to 
a little dorsad of the inner couples, for a little distance on each 
side of which the surface is raised into an eminence which carries 
the male pores [and what appear to be two pairs of accessory pores, 
which appear to be wanting in D. Perrieri \ ; in worms with 
girdles these eminences are large and bulge a little fore and aft, 
while the modification on xvii is absorbed in, or more or less 
obscured by, the girdle. 
Cetptodbilus MuDGEAxrs, n.sp. 
Five rather contracted spirit specimens from 43-58 mm. long, 
5-5’5 mm. broad ; number of .segments from about 128-145. 
Colour when alive probably pallid or flesh-coloured. Pros- 
tomium only partially divides the buccal ring. 
Setse of the outer couples further apart (about twice the dis- 
tance) than those of the inner couples, but quite as far as the two 
couples of each side: the outermost row on each side in about the 
anterior half of the body, with an occasional seta out of place, 
straight ; in the rest of the body in all the specimens these rows 
are irregularly sinuous, some of the setae being more than twice 
as far from the corresponding setae of the third row as others, but 
not alternating regularly ; quite posteriorly the third row' also 
may become irregular. 
CLiteUum comprising four complete segments, xiv-rvii, together 
with more or le^ of xiii (in one of the specimens the whole of 
XIII may be said to be included, though on the ventral surface the
