seen, stretching as a second roof over these segments; the organs only come into 
view after tearing through the membrane and liberating a large amount of flocculent 
matter. 
The seminal vesicles vaty in their distribution. In one of the dissected speci- 
mens there were four pairs, in segments xi-xiv; those in xi were contained within 
the testis-sac; those in xii were the largest; in xili and xiv they were small. In the 
other they were found in xii only. ‘The vesicles are attached to the anterior septum 
of the segment, and are of a somewhat pyriform shape, the lower end being the 
broader. The tapering upper end curves inwards towards the middle line; their 
surface is finely mammillated all over, or mammillated in the upper, smooth in the 
broader lower portion. 
The prostates extend back to the posterior septum of segment xxiii, or in the 
second specimen to xxv. They lie on the intestine and almost or quite conceal it 
from view. | 
The penial setae were 1°6—2 mm. in length. I could not see any reason for 
supposing that the concave margin of the curved distal end of the seta was sharp 
rather than, as usual, rounded. 
Remarks.—This species must, according to the finding of these specimens, be 
removed from the small number of species which have the gizzard in segment vii 
(Michaelsen, 12).

A few notes will be sufficient, for comparison with the original description. 
Prostomium epilobous 5, almost tanylobous, the tongue not delimited pos- 
teriorly by a transverse groove. 
Dorsal pores ate present, the first in groove 5/6. 
The dorsal break in the setal rings is irregular; in front of the clitellum zz is 
about equal to 3y2; behind, about 2yz. Ventrally, in front of the clitellum the 
break is small, practically absent anteriorly, increasing just in front of the clitellum 
so that here aa=14ab; behind the clitellum aa=2ab very regularly. The setae of 
segments iv-vill are very large, those of ix and x smaller but still larger than those of 
succeeding segments. In the segments behind the clitellum only, ad is greater than 
the succeeding intersetal intervals, but the difference is not great. : I did not notice 
any progressive diminution in the size of the setae on passing lateralwards from the 
mid-ventral line. The numbers counted were:—vi/39, xii/ca. 40, xix/ca. 46, more 
posteriorly ca. 50. 
There were a pair of genital papillae, small and whitish, in the situation of 
furrow 18/10, a little outside of and just posterior to the porophores. 
The gizzard was in segment vi, partly at least, and probably wholly; but I 
could not be sure that the very delicate septum 6/7 was not attached round the giz- 
zard itself; in this case the gizzard would be partly in vii. 
The testis-sacs are exactly similar to those described in the preceding species,
