This species has been found twice, at Woods Hole in 1883, and 
at Clarendon Hills, south of Boston, in 1904, under leaves in winter 
in a maple swamp, both specimens females. The male was found 
in 1906 at Portland, Me. 
The length is 5 mm. and the length of the cephalothorax 2.5 mm. 
The cephalothorax is one half longer than wide, and the projecting 
middle eyes and the black bands narrowing toward the front make 
it appear longer and more pointed at the head than in the nearly 
related species. The middle eyes of the front row are as large as 
those of the upper row, which is unusual in this family, and the 
four middle eyes form a quadrangle longer than wide and nearly 
as wide in front as behind. The front middle eyes project forward 
over the mandibles. The mandibles are wide in front, with long 
claws and have seven teeth in front, the middle one-half the 
diameter of the mandible in length. On the under side of the 
mandibles are five or six shorter teeth, Pl. XI, fig. 8d. 
The abdomen is shaped as in Linyphia phrygiana and Bathyphantes 
nebulosa, high in front and low and pointed behind. 
The colors are translucent, white and black or dark gray, all 
becoming yellow in alcohol. The cephalothorax has two wide black 
bands at the side that cover more than half its surface, leaving a 
middle light band narrowing behind and toward the front. The 
dark bands do not quite extend to the sides of the head or much 
below the eyes in front. The back of the abdomen is marked with 
a series of pairs of dark spots, in one specimen united on the 
posterior half, so that half of the back is entirely black. The legs 
have wide dark bands around the ends and middle of the longer 
joints. The sternum is gray, darkest at the sides and the coxe are 
gray at the outer ends. 
The epigynum is curved downward in a half circle and widened 
at the end, Pl. XII, fig. 8f. At the base it is as wide as long, with an 
opening at each side and a thin partition in the middle, PI. XII, fig. 8e. 
The markings are more distinct, and darker than in the European 
longidens, of which there are specimens from Germany sent by 
A. Menge of Danzig in the Museum of Zoology at Cambridge. 
The male resembles the female, except that the legs are longer, 
and the top of the head above the eyes more hairy. The male 
palpus resembles that of 7. /ongidens: the tarsus has a long tooth 
near the base on the upper and inner side which is curved back- 
ward, but is not dividéd at the end into two teeth as it is in /ongidens.
