is macerated; tlie posterior end is lacking. Setae are of fonr kinds 

 as characteristic of the genus Eupanthalis^ a typical parapodium has 5 

 to 12 geniculate pointed setae (fig. 40, a) in the ventralmost part of the 

 fascicle, about 10 spinelike aristate setae (fig. 40, c?), 1 or 2 penicillate 

 setae (fig. 40, c), and a few fine capillary setae (fig. 40, h) in the 

 superiormost part of a fascicle. The notopodium has a slender 

 aciculum.

The parapodial cord is a long, brown, stiff structure, terminating 

 at its proximal end in a coil of four or five turns within the body 

 wall (fig. 40, /). The four jaws are similar, the lower pieces each 

 with about 18 low, lateral teeth in addition to the main fang (fig. 

 40, e). Elytra are pale, translucent, smooth. They are orbicular 

 along their anterior and median sides, but along their posterolateral 

 margin they are turned up so as to form a pouch, open dorsally. 



PoJynoe viutilata was taken from the same station, at the same 

 time, as was Eupanthalis oahuensis. The two appear to be identical. 

 The former name is being retained because its type is extant.
