of the same colour as the dorsum. The parapodia (PI. XXI, fig. i) are characterised by the 

 elongated, conical shape of the neuropodium -. the notopodium is much shorter, rudimentary, 

 and its acicula is surrounded by a short cyHndrical process. The notopodial bristles (PI. XVI, fig. 6) 

 have the usual curved shape, but in stead of the numerous transverse rows they bear only 

 four teeth along their edge, one immediately below the tip : the neuropodial fascicle consists 

 of two Icinds of bristles: (i) a dorsal group with the distal part long and slender, somewhat 

 curved, serrated along its edge and separated from the shaft by a semilunar laciniate fringe 

 (PI. XVI, fig. 8), and (2) a ventral group with a short falcated distal part, also with a semi- 

 lunar fringe beneath (PI. XM, hg. 7). Dorsally this ialcated part grows more slender and 

 more straight and serrated alono- its edc^e. 



This specimen best agrees with the description and figures of Polynoc- cr'inoidicol a ^ found 

 by PoTTS on Crinoids from the Maldives.

A female specimen, broken into two fragments, indifterently preserved, without elytra and 

 cirri. The dorsal bristles like in Scalis. lons^icimis with three or four teeth ; the ventral bristles 

 finely serrated above the semilunar cusp, with curved tip. ï do not understand why Augener^) 

 States "Scaliscfosus longicim-us Schm. unterscheidet sich durch die Papillen tragenden Elytra" 

 for -Schmarda says nothing about it and figured an elytron "without papillae"; with regard to 

 Polynoc mttilmis Gr. ^), that presumably is identical with Scalis. longicirrns, Grube mentioned 

 "elytra glabra". Augener's Scalis. Hartincycri-) appears to be sufficiently characterised by its 

 hook-shaped ventral bristles in the 2'' and 3*^ segment.

Though several species of the <g(t\-\\x%Scaliseiosiis already have been described, these specimens 

 could not be identified with one of them, on account of the characteristical feature of its elytra. 

 The worm of Stat. 99 is only represented by an anterior fragment that has a length of 5 mm. 

 and consi.sts of iS segments ; the specimen of Stat. 43 is broken into two pieces and has a length of
