Family APHRODITID^. 



L.ffiTMONICE FILICORNIS Kinberg. 



Off Sable Island, Nova Scotia, 75 miles W.N.W., October 5, 75 

 fathoms, fine sand. A single fine specimen, which, however, was not 

 sufficiently closely studied to determine if it is really distinct from 

 L. armata Verrill, of the New England coast and Gulf Stream 

 slope, which many European students of the Polychaeta consider 

 to be identical. Ehlers considers L, armata to be a synonjnii of 

 L. kinbergi Baird, and records the species from the West Indian 

 region. Mcintosh reports L. flicornis from the Gulf of St. Lawrence 

 and Verrill L. armata from the Gulf of Maine, Georges Banks, etc. 



Family NEPHTHYDID^. 



NEPHTHYS C^CA (Fabricius) CErsted. 



Egg Harbor, August 10, 7 fathoms, mud ; Shoal Tickle, near Nain, 

 August 15; Port Manvers, August 21, 30 fathoms, sticky mud; off 

 Beachy Island, between Flint Island and Cape Mugford, August 22, 

 80 fathoms, soft mud ; half way between Cape Mugford and Hebron, 

 August 23, GO fathoms, mud and sand; 1 mile north of Battle Har- 

 bor, September 14, 50 fathoms, fine sand. 



Typical examples of this circumboreal species occur in considerable 

 numbers on both muddy and sandy bottoms. Those from the first- 

 mentioned habitat are chiefly of small size and are more or less deeply 

 pigmented. Those taken on sandy bottoms are colorless, like the 

 representatives of the species in southern New England, which like- 

 wise occur on sandy or stony bottoms exclusively. Packard records 

 this species from Labrador, and it is common at Eastport, as reported 

 by both Ehlers and Webster and Benedict. 



NEPHTHYS INCISA Malmgren. 



East of Cape Sable 55 miles, October 6, 85 fathoms, mud. Several 

 specimens of this species, so abundant on the soft, muddy bottoms 

 of Buzzards Bay, Massachusetts, where it was formerly erroneously 

 identified with N . ingens Stimpson. It is common in northern 

 Europe also. From TV. cmca it is readily distinguished by its much 

 shorter, prismatic body and deeply incised parapodia, as well as 

 differences in papillation of the proboscis and characters of the 

 setigerous rami and setae. 



Family NEREIDS. 



NEREIS PELAGICA Linnaeus. 



Cock Capelin, Gready Harbor, August 8, 20 miles E.S.E. of Cape 

 Sable, Nova Scotia, October 7, 70 fathoms, fine sand ; 14 miles south
