18 ZOOLOGISCHE M EDEDEELTNGEN — DEEL I. 



nearly rounded, translucent, with an eccentrical scar of attachment. Their 

 exterior half shows about twenty large, club-shaped papillae, that are 

 covered on their whole surface with small tubercles. The oirropkores 

 are situated in the line of the elytrophores ; no dorsal tubercles are pre- 

 sent. The neuropodial fascicle consists of bristles that have the distal 

 end separated from the shaft by a semilunar, laciniated cusp and are 

 provided with a bifid tip ; the ventral ones are serrated along both edges, 

 whereas the dorsal bristles have a number of laciniated fringes. The 

 notopodium is rudimentary and contains a number of faintly bent, undi- 

 vided setae with some laciniated fringes along their edge. 



Scalisetosus tentaculatus n. sp. 



Siboga-expedition, Stat. 49 a , Sapeh-strait ; Stat. 274, east off Aroe-islands. 



The prostomium has a deep incision, from which the tentacle arises, 

 that is long and slender, about twice as long as the lateral antennae. 

 The eyes are inconspicuous, situated in front of the posterior margin of 

 the head. The elytra are large, overlapping each other in the median 

 dorsal line; they have an elliptical shape, with the scar of attachment 

 situated eccentrically and the distal half of the surface covered with 

 small, oval papillae. The notopodial bristles are stout, slightly curved, 

 usually provided with two spines, situated at some distance from the tip. 

 The neuropodial fascicle contains two kinds of setae: 1° the dorsal ones 

 slender, with their distal part beyond the semilunar cusp finely serrated 

 with a feebly bifurcated tip ; 2° ventral bristles, that are shorter, stouter, 

 hook-shaped with their distal part serrated along both edges. This spe- 

 cies is closely allied to Scalis. laevis Mrz. l ). 



Admetella Mc Intosh. 2 ) 



Body elongate with 75 segments; 30 pairs of scales, inserted to seg- 

 ments 2, 4, 5, 7 . . . . 23, 26, etc. Head with the lateral frontal corners 

 elongated, triangular; eyes absent. Both lobes of the parapodia with an 

 elongated distal extremity; their bristles long, vitreous. 



Admetella longipedata Mc Int. 



Siboga-expedition, Stat. 316, east off Paternoster-islands. 



At the above-named Station, in a depth of 538 M., two specimens 

 were dredged, that must be identified with Admet, longipedata, first 

 dredged by the Challenger east off Prince Edward island at 1375 fath.
