extend beyond half the length of the neuropodial one. The notopodial bristles (PI. XXI, fig. 6) 

 are stout, slightly curved, usually provided with two spines, situated at some distance from 

 the tip; in some of them only a single spine is present. The neuropodial fascicle contains two 

 kinds of setae : i" the dorsal ones (PI. XXI, fig. ~i a) are slender, about twice as long as the 

 notopodial bristles and have the distal part beyond the semilunar cusp linely serrated with a 

 faintly bifurcated tip ; 2" the ventral bristles are shorter, stouter, hook-shaped with their distal 

 part serrated along their edge. 



This species certainly is closely allied to Scalis. lacvis Mrz. '), that however is distin- 

 guished by having the elytra covered with slender, cylindrical papillae, whereas the notopodial 

 bristles are quite smooth or provided with a single tooth.

An anterior fragment of an other Scalisetosus-^'^&üt.'i, measuring 5 mm. in length, is 

 characterised by its shining white prostomium, whereas the dorsum of the body is marbled 

 with black. All cirri and elytra are absent. The prostomium is nearly round, divided by a 

 -median dorsal groove, that widens anteriorly, in two semilunar halves ; two pairs of pale, large 

 eyes are situated laterally on its posterior half. Both lobes of the parapodia (PI. XXI, fig. 8) 

 have an elongated, pointed, distal e.xtremity, surrounding the tip of the acicula. The notopodial 

 bristles (PI. XXI, fig. 10) are till their distal end provided with laciniated fringes ; the neuro- 

 podial ones (PI. XXI, fig. 9), that show the usual semilunar cusp, have a faintly bifurcated 

 tip and are feebly serrated along their edge.
