each convex curve of the sinuosity including a black spot; the 
sides have a yellowish-white hue, their lower part being densely 
marked with pale-brown streaks and spots; the under part is of 
a dull-yellow colour, and comprises three longitudinal dark- 
brown bands, which meet at the spinners. The eyes are seated 
on black spots, and are disposed on the anterior part of the 
cephalothorax in two transverse rows; the four intermediate 
ones describe a trapezoid, the two anterior ones, which are placed 
on a protuberance, and are much wider apart than the posterior 
ones, being the largest of the eight; the eyes of each lateral 
pair are seated obliquely on a minute tubercle, and are near to 
each other, but not in contact. The cephalothorax is compressed 
before, rounded in front and on the sides, convex, glossy, with 
an indentation in the medial line of the posterior region ; it is of 
a yellowish-brown colour, the cephalic region being much the 
palest, and has a narrow brown band extending along the mid- 
dle. The falces are conical, vertical, armed with teeth on the 
inner surface, and have a pale brownish-yellow hue. The 
maxille are straight, and rounded at the extremity; and the lip 
is semicircular, but slightly pointed at the apex. These organs 
are of a brown colour at the base, that of their extremities being 
pale yellow. The sternum is heart-shaped, with eminences on 
the sides, opposite to the legs, and has a dark-brown hue tinged 
with red. The legs are moderately long, sparingly provided 
with hairs, and of a dull brownish-yellow colour; the first pair 
is the longest, then the second, and the third pair is the shortest; 
the tarsi are terminated by claws of the usual number and 
structure. The palpi are short, and paler than the legs. The 
very tumid digital joint of this specimen indicates that it had to 
undergo its final ecdysis before it arrived at maturity. 
The immature male described above was the only individual 
of this species comprised in the collection. 
Epeira dorsuosa, n. sp. 
Length of the female 4 an inch; length of the cephalo- 
thorax +, breadth +; breadth of the abdomen 4; length of an 
anterior leg ;7,; length of a leg of the third pair 2. 
The eyes are disposed on the anterior part of the cephalo- 
thorax in two transverse rows; the four intermediate ones, which 
are the largest, are seated on a prominence, and nearly form a 
square ; and the eyes of each lateral pair are placed obliquely on 
a tubercle, and are separated by a moderately wide interval. 
The cephalothorax is compressed before, rounded in front and 
on the sides, convex, clothed with hoary hairs, and has an in- 
dentation in the medial line of the posterior region; it is of a 
yellowish-brown colour, with a longitudinal dark-brown band in 
the middle, which is broadest in the cephalic region, and anothe
