fringe. Setae and acicula are pale yellow. Notopodial setae are of two 

 kinds, ( 1 ) numerous, fine, bipectinate setae in the upper and median 

 parts of the fascicle (pi. 18, fig. 220), and (2) inferior, simple capillary 

 setae (pi. 18, fig. 223), as also intergradations of these two kinds. 



Parapodia have numerous fimbriae, bordering the setal fascicles on 

 the anterior and dorsal faces of the podal rami. These are most con- 

 spicuous on the first 15 segments. More posteriorly they diminish in 

 size and number and by the twenty-fifth parapodium are much reduced. 

 A few, however, at the anterodorsal edge of the notopodium and the 

 dorsal edge of the neuropodium are present throughout (pi. 18, fig. 

 217). A conspicuous feature is the presence of 2 lobes at the ectal 

 margin of the notopodium. 



Leanira fimbriarum differs from typical representatives of this genus 

 in that its inferior neuropodial setae are not canaliculate. The pro- 

 stomium has well-marked eyes, and the elytra are fimbriated.

Genus PSAMMOLYGE Kinberg 



Body elongate, consisting of numerous segments. Prostomium sub- 

 circular or oval, widest posteriorly; without eyes or with 4 eyes on the 

 anterior half. A median antenna inserted on a stout ceratophore with- 

 out ctenidia. The paired prostomial antennae inserted on the peristomial 

 segment. Parapodia subbiramous, the notopodium short, with only fine, 

 hair-like, serrated setae; the neuropodium stout, with composite setae, 

 the shaft smooth or spinose, the appendage usually falcate distally, the 

 tip entire or bifid. Elytra encrusted with sand particles, the margin 

 fimbriated, and produced in lobes at the median, and sometimes also 

 posterior, margins.
