Cape Sable, Nova Scotia ; G species have not previously been reported 

 from American waters. In the following list it will be understood 

 that where the name of the Province is omitted the locality is in 

 Labrador, 



Family SILLID^. 



AUTOLYTUS LONGISETOSUS (CErsted) Malmgren. 



A single male epitoke taken in the tow^ net off Egg Harbor, August 

 10, agrees closely with the descriptions and figures of this northern 

 species given by Oersted, Malmgren, and Verrill. The number of 

 segments (30) in the caudal region is, however, greater, but their 

 total length bears about the same proportion to the other regions. 

 There are G setigerous segments in the anterior and 30 in the middle 

 or swimming region. Notocirri of the anterior region bear a large 

 dorsal basal gland, probably represented in Oersted's figure as a 

 thickening of this region. Some confusion exists in the American 

 records of this species. Verrill reports it from Massachusetts Bay. 



Family PHYLLODOCIDiE. 



PHYLLODOCE MUCOSA CErsted. 



Port Manvers, August 21, 30 fathoms, sticky mud; halfway be- 

 tween Cape Mugford and Hebron, August 23, GO fathoms, mud and 

 sand. This species resembles very closely P. pulchella Malmgren 

 and P. catenula Verrill. From the latter, so common on the New 

 England coast, it differs in the form of the notocirri and especially 

 in the greater number and smaller size of the papilla? of the basal 

 division of the proboscis. The nuchal papilla, so generally over- 

 looked in members of this genus, is present. The only published 

 American Atlantic record is that of Webster and Benedict for 

 Eastport. 



PHYLLODOCE, species. 



Off Beachy Island, between Flint Island and Cape Mugford, 

 August 22, 80 fathoms, soft mud. A young specimen 18 mm. long; 

 resembles P. jmlchella rather more closely than P. mucosa^ except in 

 the relative length of the seta appendages. 



Family POLYNOID^. 



HARMOTHOE IMBRICATA (Linnaeus) Malmgren. 



Egg Harbor, August 10, 7 fathoms, mud; Shoal Tickle, southeast 

 of Nain, August 15; 20 miles northeast of Nain, August 20; Koma- 

 toroic Bay, north of Nakoak, August 28, 5 fathoms, rocky; off St. 

 Lawrence Harbor, Placentia Bay, Newfoundland, September 29; St.
