FROM THE MONTEBELLO ISLANDS. 85 
OLIos HERMITIS, sp.n. (PI. II. fig. 9.) 
1 female (P. D. M.) non-adult. 
2 females (T. H.) (1 ceph. only). 
These specimens, none of which is quite adult, are very close 
to L. Koch’s Olios (Sarotes) procerus from the east coast. They 
differ, however, in the front median eyes being smaller instead 
of larger than the rear median. The clypeus is as wide as the 
distance between the front and rear median eyes—plus the 
diameter of a front median. The lip is less than half the length 
of the maxille instead of half as long, and the legs are more equal 
in length, the fourth pair being equal to the front pair, and 
the second only slightly longer. It is therefore worthy of being 
made a new species. 
The cephalothorax is yellow-brown, with a rather broken 
yellow-brown marginal stripe on the thoracic part, a similar 
horseshoe pattern of large brown spots nearer the centre with a 
single spot between the forward pointing open ends. The eye- 
space is black-brown, and there are two fainter brown spots 
behind the rear row. The hair is fine and silvery white, but 
brown on the spots. The mandibles are yellow with a brown 
stripe on the outer edge reaching rather more than halfway from 
the base, and the fangs are brown. On the inner edge of the falx- 
sheath are three large teeth followed by one small one; on the 
outer margin one large between two small. The lip, maxille, and 
sternum are darker yellow with brown bristly hair. 
The legs are orange, with three brown rings on the femur, 
1 on the patella, 2 on the tibia, and 2 on the metatarsus of each 
leg. The scopula on the metatarsus and tarsus are grey, and the 
claw-tufts nearly black. There are two very long spines, one in 
front of the other, on the under side of the tibial joint. The 
tarsal claws are long, with about 10 pectinations on a straight 
shaft bent at the anterior end, and the female palp-claw has 
about half that number. 
The measurements (in millimetres) of the largest (front pair of 
legs only) and of a smaller whole one, are as follows :—
