CHONE, species?. 



Near Egg Harbor, August 10, 20 fathoms, rocks. Portion of 

 caudal end of a specimen 3 mm. in diameter. The abdominal uncini 

 have much longer beaks than those of the specimens of C. infundi- 

 Jjuliformis^ longer, indeed, than figured for any of the North Atlantic 

 species. They resemble those of C. duneri Malmgren rather more 

 closely. 



EUCHONE TUBERCULOSA (Kroyer) Malmgren. 



Off Beachy Island, between Flint Island and Cape Mugford, Au- 

 gust 22, 80 fathoms, soft mud. Two fine specimens. One is 31 mm. 

 long, the gills being 8.5 mm., the other slightly longer. Both are 

 colorless and both have the left ventral plate of the first abdominal 

 segment more than twice as large as the right and extending in front 

 of it. Tubes of fine silt, terete, 103 mm. long and 2 mm. in diameter. 



EUCHONE RUBROCINCTA (Sars) Malmgren. 



Egg Harbor, August 10, T fathoms, mud. A small specimen 12 

 mm. long. This is an addition to the North American fauna, but the 

 two preceding species have been taken by Verrill in northern New 

 England. 



POTAMILLA NEGLECTA (Sars) Malmgren. 



Off Cape Sable, Nova Scotia, 14 miles south, 45 fathoms, rocky; 

 76 miles WNW. from Sable Island, 75 fathoms, fine sand; Browns 

 Bank, off Cape Sable, October 8, 40 fathoms, rocky and sandy. 



The four specimens are larger than is usual for the species in north- 

 ern European waters, having a thoracic width of 2.0^ mm. The 

 gills, of which there are 15 or 16 pairs, are either colorless or more 

 or less diffusely colored with pale chestnut or orange brown. Re- 

 ported by Webster and Benedict from Eastport and by Verrill from 

 Georges Banks.

FILOGRANA FILOGRANA Berkeley. 



Browns Bank, off Cape Sable, Nova Scotia, October 8, a small 

 group of tubes of this species, which occurs southward to Marthas 

 Vineyard. 



SPIRORBIS SPIRILLUM Linnaeus. 



Egg Harbor, August 10, 7 fathoms, fine mud; Shoal Tickle, 20 

 miles southeast of Nain, 25 fathoms, gravel ; outside of Hebron, Au- 

 gust 25, 60 fathoms, gravel; Browns Bank, off Cape Sable, Nova 

 Scotia, October 8, 40 fathoms, rocky and sandy. Most of the speci- 

 mens are of the ascending (lucidus) form attached to bryozoans and
