Dorsal view of the head. Head (fig. 8) epilobous (about %). Prostomium broad and rather short, uniformly rounded; dorsal appendage of the prostomium broad, narrowing posteriorly, with two narrow, transverse furrows near each other, and near the hinder edge of the appendage, the converging lateral borders of the appendage reaching only a very little distance (sometimes not at all ?) over the hindmost furrow. Setae rather strictly paired, the lateral perhaps a little more so than the ventral, the difference scarcely noticeable; median-ventral distance a little smaller than the middle lateral ones, median-dorsal distance in general equalling half the circumference of the body (approximately aa: ab: be: cd: dd:=8: 3: 9: 3: 37; dd=Y2 v)\ towards the clitellar region the setae appear to be very slightly dislocated in a ventral direction, not so much so, however, as that the lateral ones could be called ventral. The setae are moderately large, the ventral very little larger than the lateral, but this difference is slight. Clitellum annular, occupying segments XIV-XIX ( = 6), but be- coming indistinct towards the intersegmental furrows XIII/XIV and XIX Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustr
