peristomium, which form a thick reflexed margin. Tentacles smooth. Branchiae four on 

 each side, affixed to the third and fourth segments (ten to twelve, Malmgren). Body 

 10 — 12 mm. long, 25 mm. at its widest part, gently tapered in front, somewhat flattened 

 from above downward, and diminishing gradually to the tail. Fourteen bristled segments 

 occur anteriorly and twelve in the posterior region, the last having two short subulate 

 caudal cirri ; anal papillse small. Nephridia in the fourth, fifth, sixth and seventh segments. 

 Bristles with slightly curved, winged, and tapering tips. Hooks have a sinuous crown,

The prostomium is characteristically bifid, supported laterally and posteriorly by the 

 folds of the peristomium, which form a thick, reflexed margin, the whole giving the 

 cephalic region considerable breadth, and it is also bent downward. According to 

 Malmgren the filiform tentacles are smooth.
