Of this remarkable spider three full grown males and two 
females were captured at Polaris Bay, June 3, 1872. 
2. Erigone penessa, n.—Black, with palpi and legs blackish-yel- 
low, mandibles yellowish, longitudinally striped with black; pars- 
cephalica elevated, strongly convex transversely, lateral eyes not 
contiguous, anterior laterals largest of the eight, oval and oblique, 
area occupied by the middle eyes (of which the anterior are 
slightly smaller than the posterior, and separated by a very small 
interval), rather longer than broad, much broader behind than in 
front; vulva consisting of a shallow transversal fovea, limited be- 
hind by a brown shining costa narrowing from the extremities 
towards the middle, and slightly curved forwards. 9 ad. Length 
nearly 3 millim. 
emale—Cephalothorax inversely ovate, shining, rather shorter 
than tibia and patella of the fourth pair, moderately rounded in 
the sides of the pars thoracica, rather strongly narrowed and 
slightly sinuated at the pars cephalica; the forehead is rounded, 
and its breadth equals about two-thirds of the breadth of the pars 
thoracica; the cephalic furrows are strongly marked; the pars 
cephalica is elevated and transversely very convex, and provided 
with several short hairs between the eyes, and a longitudinal row 
of three longer hairs behind. Seen in profile the back of the ce- 
phalothorax rises gradually from the hind margin to the hinder 
part of the pars cephalica, the back then becoming somewhat 
sloping forwards, and very slightly convex; a slight depression 
is seen between the pars cephalica, and the pars thoracica. The 
front row of eyes is seen from before, nearly straight, but slightly 
curved upwards; the hind row is curved forwards. The four 
central eyes occupy an area slightly longer than broad behind, 
and much broader behind than in front; the lateral eyes of either 
side are separated by a very distinct interval (not contiguous), and 
placed on a protuberance. The anterior lateral eyes are the largest 
of the eight, oval and obliquely posited; the anterior centrals ap- 
pear to be a little smaller than the posterior eyes ; they are prom!- 
nent, only separated by a very small interval, and their distance — 
from the margin of the clypeus is double as great as their diame; 
ter; the interval between them and the anterior lateral eyes 15 
somewhat greater than the diameter of these last named eyes. 
he intervals between the four posterior eyes, which are very 
nearly of the same size, are nearly equal, and at least half again as 
great as the diameter of an eye. Sternum large and broad, con- 
vex towards the margins, shining, sparingly spread with fine hairs. 
-Mandibles somewhat ovate, nearly double as thick as the fore
