hairs. There are narrow bands of red hairs on each side, be- 
]ow the eyes, and some scattering long black hairs behind the 
anterior lateral eyes. The abdomen is yellow marked with a 
number of small black spots. There is a yellowish golden, 
median longitudinal band, on either side of which are red 
bands. Just above the spinnerets the two bands unite. In 
the posterior half, in the red hands, are three or four pairs 
of white spots. In some specimens the red bands are absent. 
The legs are yellow, the 1 femjur of the first having transverse 
dark striae in front. 
This species is nearest Leighii , from which it is distinguished 
by the following points : Ogdenii is a smaller and lighter col¬ 
ored species with the relative length of the legs 1342 instead 
of 1324; in Ogdenii the spines under the tibia of the first are 
placed, along the length of the joint, at nearly equal distances, 
while in Leighii the two at the proximal end (one on the an¬ 
terior and one on the posterior face), are much more widely 
separated from those at the distal end than these are from 
each other, those at the distal end being also separated from 
each other by unequal distances. Both species have two small 
lateral spines on the tibia of the second. 
We have this species from Mashonaland (Mr. Marshall), 
Durban (Mr. Quekett), and Algoa Bay (Dr. Brauns). It is 
named for Dr. H. Y. Ogden, of Milwaukee.

This species has a light and a dark variety, and varies con¬ 
siderably in size. 
$. Length 9.5 mm. Legs 1324, first pair stoutest, second 
next. 
The quadrangle of the eyes occupies two-fifths of the Cephas 
lothorax and is equally wide in front and behind. The front 
eyes are a little separated and form a straight row, the mid¬ 
dle being twice as large as the lateral. The second row is 
plainly nearer the first than the third, and the third is much 
narrower than the cephalothorax.
