spirally arranged fine spinous rows, tapered rather abruptly to very 

 thin tips (fig, 4c). 



Anus dorsal in position, surrounded by last few small segments 

 (damaged somewhat in this area) . Anal cirri not observed. Nephrid- 

 ial papillae on ventral bases of parapodia, beginning on segment 4 

 and continuing posteriorly, small at first, becoming longer (shorter 

 than ventral cim), cylindrical and directed between the parapodia 

 (fig. 4a). Pharynx not extended. The single specimen is ovigerous. 



Remarks: Bathyadmetella commando is unique among the polynoids 

 in having long antennal and tentacular sheaths and lamellar papillae 

 on the ventral lip and ventral bases of the second and third segments. 

 It is also unusual for its extremely large bulgmg eyes. It may be 

 distinguished from Admetella and Bathymoorea according to the key 

 on page 13. 



Distribution: Northeastern Pacific (off Oregon). In 900 fms. 



Bathymoorea^ new genus 



Type species: Polynoe(?) renotv.hulata Moore, 1910. Gender: 

 feminine. 



Diagnosis: Polynoids with relatively few segments (33). Pro- 

 stomium with 2 long palps and 3 antennae; median antenna with 

 ceratophore inserted in middle of prostomium; lateral antenna in- 

 serted on anterolateral extensions of prostomium (i.e., lepidonotoid) . 

 Tentacular segment (I) achaetous, with 2 pau's tentacular cuTi, 

 with bulbous facial tubercle between bases of palps. Buccal segment 

 (II) with first pair elytra, setigerous parapodia, and long ventral 

 buccal cu-ri. Elytra 14 pau's, arranged on segments 2, 4, 5, 7, then 

 on alternate segments to 23, 26, 28, and absent on last 5 small seg- 

 ments. Parapodia elongated, subbiramous, with small notopodia; 

 both rami with elongated, digitiform acicular processes. Notopodia 

 with small tufts of setae. Notosetae delicate, finely spinous. Neu- 

 ropodia with dense, brushlike bundles of transparent setae. Neuro- 

 setae distally expanded and flattened, with famt spinous rows and 

 tapered tips. Nephi-idial papillae remarkably elongated, some ex- 

 tending to tips of neuropodia.
