166 EULEPIS MALAYANA. 



is not attached to the 23''^^ segment, like in the Polynoidae, 

 because it is separated from the foregoing by two branchiae- 

 bearing segments. The long elytrophores as well as the 

 branchial processes are inserted quite next to the median 

 dorsal line. The dorsal appendages of the segments without 

 elytra more resemble the branchial processes of a Sigalionid 

 than a cirrus, for they show a row of cilia at their ven- 

 tral side, whereas also one or more groups of cilia are 

 situated opposite on the dorsum of the notopodium. However 

 it differs from a Sigalion-branchia therein that it consists 

 of a broad basal portion and a narrower, cirrus-like distal 

 part, separated from each other by a septum. In the seg- 

 ments, situated more posteriorly, this cirrus-like part be- 

 comes larger and longer. The basal part contains a peri- 

 toneal cavity, in which an intestinal coecum enters and 

 also some eggs are visible; its wall, agreeing with Dunc- 

 ker's description '), shows a thin layer of longitudinal 

 muscles and an epidermis-layer, that is very thick at the 

 ventral side of the branchia. At the dorsal side a comb- 

 like ridge is situated, consisting of numerous cells with 

 coarsely-granular contents, presumably of a glandular nature. 

 The distal part consists of large polygonal cells. The third 

 segment has a short, conical dorsal cirrus and at first 

 shows in its notopodium the stout brown bristles, with the 

 tip bent at a right angle towards the shaft, characteristic for 

 this genus ; beneath them is a fascicle of slender, capillary 

 bristles, finely serrated along the edge. The neuropodium 

 contains a fascicle of stout yellow setae, winged along 

 both edges and with a fine capillary tip; only the supe- 

 rior of them is shorter and pectinated beneath the tip. 

 This comb consists of about a dozen of large teeth, decrea- 

 sing distally in length, and of a great number of small 

 ones. This pectinated bristle was first observed by Mc.
