NO. 1703. SOME POLYCH.l^TOUS ANNELIDS— MOORE. 143 



diameter is from 0.8 to 3.2 mm. The only obvious feature in which 

 these specimens differ from typical examples of the species is the 

 elevation into a ridge of the transverse glandular bow on the dorsum 

 behind the fifth fascicles of seta?. An abundant circumboreal species 

 well known from the coast of northern New England. 



Family CHLORH.^MID.^. 



BRADA GRANULATA Malmgren. 



Halfway between Caj^e Mugford and Hebron, August 23, GO fath- 

 oms, mud and gravel ; off Fish Island, outside of Hebron, August 25, 

 75 fathoms, mud ; outside of Hebron, xVugust 26, 80 fathoms, gravel. 



These are stout grub-shaped worms measuring 40^5 mm. long 

 and 9-13 mm. in diameter, with 21-23 setigerous segments. There 

 is little doubt that they belong to Malmgrens species, but it seems 

 probable that this is identical with B. suhlevis Stimpson described 

 from the Bay of Fundy in 1853, as has been suggested already by 

 Webster and Benedict. 



TROPHONIA ASPERA Stimpson. 



Egg Harbor, August 10, 7 fathoms, mud ; Nain, August 18, 7 fath- 

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

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

 80 fathoms, soft mud; outside of Hebron Harbor, August 25, 60 

 fathoms, gravel. One specimen from each station; a complete one 

 has 32 segments and a length of 45 mm. A tuft of seven rather thick 

 tentacles, having a length equal to one-half the body diameter, is 

 exposed on one side. The setae of the first three segments are very 

 long, and the first five tufts of notopodials are directed forward. 

 This is one of the species reported by Packard. 



FLABELLIGERA AFFINUS Sars. 



Egg Harbor, August 10, 7 fathoms, mud ; outside Hebron, August 

 26, 80 fathoms, gravelly; 55 miles east of Cape Sable, Nova Scotia, 

 October 6, 85 fathoms, mud. One specimen from each station, 22 to 

 60 mm. long. This species and the next are European forms well 

 known on our coast as far south as Casco Bay. 



Family SCALIBREGMID^. 



SCALIBREGMA INFLATUM Rathke. 



Off Cape Sable, Nova Scotia, 55 miles east, October 6, 85 fathoms, 

 mud. One much macerated specimen.
