The capillary seta? form large fascicles and are very long and slender, 

 nearly smooth, and with very attenuated tips ; their length is about 

 three times that of the appendages themselves; the transversely 

 marked seta? are scarcely one-fourth as long, and about the same in 

 diameter, with very slender tips. — A. E. V.

This is the most common and abundant species on muddy bottoms 

 in the deep water along the whole New" England coast. It occurs at 

 all depths from 2 to 430 fathoms. 



It is easily distinguished by the stout quadrangular body, deeply 

 incised posteriorly; by the blackish setae, and by the remarkably 

 elongated and widely separated rami of the posterior appendages. 

 There is a long, odd, median papilla on the dorsal side of the proboscis, 

 and a smaller one beneath ; the papillffi in the longitudinal rows are 

 rather small. — A. E. V.

George's Bank, 50 fathoms (locality d). It also occurs at Watch 

 Hill, llhode Island, in 4 to 6 fathoms, among rocks and alga?, and in 

 tide-pools ; at Wood's Hole, at surface, evening, July 3 ; in Cuasco 

 Bay, 8 to 30 fathoms ; and is very common in the Bay of Fundy, 

 from low-water to 50 fathoms. 



This species is closely allied to P. ptdchella Malmgren, from north- 

 ern Europe, but differs somewhat in the form of the head, which is 

 shorter and rounder in the latter; the branchia? also differ in form.
