INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 583 



slender setie, as long as the median antennje. The palpi are slender,, 

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

 scales; setcne 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, th€ 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""^ : breadth usually about 4""". 



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

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

 Egg Harbor (Leidy). 



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

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

 determine whether he observed the same species. 



Kephthys ingens .Stimpson. Plate XII, figs. 59, 60. (p. 431.) 



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



Long Island Sound, off New Haven, 3 to 8 fathoms, mud, common 5 

 off Block Island, in 29 fathoms; Bay of Fundy, 10 to 60 fathoms. 



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

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

 I)roboscis, and the smaller ventral one; by the very prominent and widely 

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

 It grows to the length of 130°^"* or more.

Vineyard Sound, 8 to 10 fathoms, shelly ; Watch Hill, Ehode 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 setie, 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
