Family STERNASPID.^. 



STERNASPIS FOSSOR Stimpson. 



Off Cape Sable, Nova Scotia, 55 fathoms east, September (), 85 

 fathoms, mud. 



These siDecimens are identical with some collected near the type 

 locality by Dr. Harold S. Colton. They differ greatly from the 

 southern New England species which has long gone under Stimpson's 

 name, but which I am unable to distinguish from Mediterranean 

 examples of S. scutata (Ranzani). S. fossor has seven segments 

 between the genital pores and the anterior margin of the caudal 

 shields, which have obscure ridges and a bright ferruginous color. 

 The cuticle is more or less densely pilose, especially behind the genital 

 pores, where most of the cutaneous papillae become aggregated in a 

 regular row of low tufts on many of the segments; above the region 

 of the caudal shield they become longer and almost filamentous. 

 Southern specimens, in striking contrast, have eight segments between 

 the genital pores and the caudal shield and the cuticle is nearly 

 smooth. The ranges of these two species on our coasts can not now 

 be stated. 



Family ERIOGRAPHID.E. 



MYXICOLA STEENSTRUPI Kroyer. 



Browns Bank, off Cape Sable, Nova Scotia, October 8, 40 fathoms. 

 A young specimen having a total length of 22 mm. and a maximum 

 width of nearh^ 2 mm. Perfectly colorless except for segmental pairs 

 of conspicuous lateral, small, nearly black eye-spots, arranged in a 

 somewhat irregular series on each side. Common at Eastport and 

 reported by Verrill from Casco Bay, Maine. 



Family SABELLID^. 



SABELLA CRASSICORNIS Sars. 



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

 fathoms, fine sand. A single specimen 24 mm. long with 14 pairs 

 of branchiae 8 mm. long marked with five or six regular pale brown 

 bands, at each of which, except the first, a pair of large dark-brown 

 eye-spots is borne on the back of each rachis. The rather stiff tube 

 is strengthened with fine sand grains. Not previously reported from 

 our coasts, though the related S. pavonica is well known in New 

 England waters. 



CHONE INFUNDIBULIFORMIS Kroyer. 



Same station as last. Two specimens.
