[583] INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 289 



slender setse, as long as the median antennae. The palpi are slender, 

 longer than the antenna? ; lateral feet prominent, projecting beyond the 

 scales ; setse light yellow. 



Color variable, generally light gray, with a dark brown median dorsal 

 band, each scale often bordered on the posterior and inner edges with 

 brown, which is connected with a blackish angular spot near the ante 

 rior margin, the rest of the scale being transparent and whitish ; head 

 dark brown, with a red central spot and a round whitish spot on each 

 side. Length up to 150 mm ; breadth usually about 4 mm . 



Vineyard Sound, low-water mark to 14 fathoms ; off Martha s Vine 

 yard, 21 fathoms, sand; off New Haven, 4 to 5 fathoms, shelly. Great 

 Egg Harbor (Leidy). 



This species differs considerably in the form of the head, antennae, 

 &c., from the figure given by Leidy. His description is insufficient to 

 determine whether he observed the same species. 



NEPHTHYS INGENS Stimpson. Plate XII, figs. 59, GO. (p. 431.) 



Marine Invertebrata of Grand Manan, p. 33, in Smithsonian Contributions, 1853. 



Long Island Sound, off New Haven, 3 to 8 fathoms, mud, common ; 

 off Block Island, in 29 fathoms; Bay of Fundy, 10 to GO fathoms. 



This species is readily distinguished by the form of the head and 

 position of the small antennae; by the large median dorsal papilla on the 

 proboscis, and the smaller ventral one; by the very prominent and widely 

 separated rami of the posterior feet; and the dark color of the setaB. 

 It grows to the length of 130 mm or more.

Die Borstenwiirmer, vol. i, p. 617, PI. 23, fig. 8. 



Vineyard Sound, 8 to 10 fathoms, shelly ; Watch Hill, Rhode Island, 

 4 to 5 fathoms, among rocks and sand. Massachusetts Bay (Ehlers). 



This species is remarkable both for the form of the head and the 

 length of the setre, which often exceed the diameter of the body.

Ehlers gives Edgartown as a locality for this species. It is a northern 

 form, found at Iceland, Greenland, Spitzbergen, and along the northern 

 coasts of Europe and Great Britain. Stimpson records it from the
