area iS rather flat and covered with particularly smooth long 
hairs all lying longitudinally. 
The front row of eyes is straight, the median pair their 
diameter apart and 14 times the same distance from the laterals, 
which ave only half their diameter. -These are also their dia- 
meter from the rear laterals, the diameter of the latter being 
half as large again, and farther away, sideways, by the bred 
of the front laterals. The rear median are the same size as the 
front median, two diameters therefrom and 14 diameters from 
one another. Therefore they form with their laterals a strongly 
procurved row. 
The mandibles are short and conical, only slightly kneed at 
the base and divergent at the anterior end, ‘The fangs are 
slightly curved and rather long. On the upper part of the outer 
margin of the falx-sheath is one long tooth between two shorter, 
and on the inner in the same position three also, the lowest being 
the largest. 
The maxille are convex, as long as broad, obtusely arched on 
the upper edge and rounded at the back. The lip is broader 
than long, curved to an obtuse angle in front, where it is very 
convex, with a short narrower lower stem. 
The sternum is shield-shaped, scolloped at the sides, half as 
long again as broad; opposite the second and third coxe the 
median area is projected into high round protuberances, and at 
the posterior end is a similar but still larger oval knob. The 
hair is downlying, finer at the sides than in the middle streak, 
and there are a few long bristles at the anterior end. 
The abdomen is 23 times as long as its breadth in the middle, 
whence it tapers to a narrow rounded point at each end. 
On the under side the base is less constricted and more rounded 
off. the sides are straighter until beyond the spinnerets, where it 
is suddenly narrowed into a stunted tail. On the back are four 
pairs of muscle-spots. 
The epigyne is formed in the same unique fashion as in 
A. protensa and A. syrmatica, a chitinous cushion-like pear- 
shaped projection, broadest at the base and having a blunt ova! 
fore end, standing straight up. The basal end is about one-third 
of the whole breadth of the abdomen at that part. 
The legs are rather long and very fine in the anterior joints, 
the tibia broadened out and flattened at the anterior end, and the 
trochanter of the fourth pair nearly as long as the coxe. 
The femoral joint of the palpi is strongly incurved, and broadest 
at the anterior end. The tibia is twice as long as the patella, and, 
the metatarsal jomt is covered with long bristly hairs. 
The measurements (in millimetres) are as follows :—
