EUNOE EURA. 59 



of lateral tentacles less than half as long as that of the median, half its greatest 

 width; lateral tentacles as wholes manifestly shorter than the prostomium; 

 styles at proximal end as wide or wider than ceratophore, conically narrowed 

 distad, the apical portion slender and acute; no distal enlargement whatever; 

 sensory processes numerous, strictly cylindi'ical, transi^arent. Palps terete, 

 slenderly conical, the tips very slender and acute, the total length about thi-ee 

 and three fourths times as great as that of the prostomium; cilia arranged in 

 longitudinal rows as usual, each small, cylindrical, or sometimes enlarged dis- 

 tally, transparent, arising from a sUght tubercle. (Plate 3, fig. 2, 3). 



Peristomial parapodia bearing two curved setae; the ceratophores prominent, 

 reaching beyond anterior border of prostomium; styles missing in type. Peri- 

 stomium not evident dorsally. 



Metastomial somites conspicuously arched above over entire length of 

 body but somewhat more depressed caudad; ventrally less strongly arched. 

 Pygidium very small; no subanal cirri detected. Neural groove sharply defined, 

 rather wide. Nephridial papillae beginning on the fifth somite, on which they 

 are minute; at twelfth and thirteenth somite obviously increasing abruptly 

 in size, which is uniform from there caudad; papillae bending dorsad into the 

 intersegmental furrows. 



The parapodia of the middle region of the body are very long, being three 

 fifths as long as the width of the somites; stout, little compressed. The noto- 

 podiiun is much smaller than the neuropodium, appearing upon the antero- 

 dorsal surface of the latter as a small lobe near the middle of its length, the distal 

 end of the notopodium falling far short of that of the neuropodium; in the form 

 of a short, somewhat obliquely truncated and but little compressed cylinder 

 which bears the numerous setae on its distal surface and at the caudal the usual 

 finger-like process which is cyUndrically or distally somewhat enlarged, which 

 reaches to near the distal end of the neuropodium, and through wliich the aci- 

 culum extends. Neuropodium strongly compressed subdorsoventrally, thicker 

 at base than distad, the distal edge rising from caudal end cephalad to an 

 angular apex from which arises the finger-shaped process, this being of the same 

 form and size as that of the notopodium, and much shorter than the setae; 

 the aciculmn extends into the process as usual. 



Ventral cirri arise at middle of length of parapodia. Each, when laid against 

 the parapodium, reaches the apex of the latter, the base of the finger-hke process; 

 the cirrophore is a conspicuously thickened tubercle; the filament is slenderly sub- 

 ulate and smooth. The dorsal cirrophores are large cylindrical processes which lie
