The chelicerae are armed with a row of denticles on the inner 
side only. 
The trochanters of the pa/ps are not scopulate; their vestiture 
resembles that of the trochanters of the legs. The tarsal scopulae 
of the palps (?) resemble those of the first legs. The penulti- 
mate joints are not scopulate. 
The first Jegs are almost always shorter than the fourth’, the 
second than the first, and the third than the second. The tarsal 
scopulae of the first legs are (? always) divided (? sometimes 
imperfectly especially in the male). The tarsal scopulae of the 
fourth legs are always divided in both sexes, and in the female at 
least the division is sometimes so broad that the scopula appears 
only as a pair of narrow lateral bands. The spiney armature of 
the legs does not reach its full development in all forms; and it 
is noteworthy that this is especially the case in relatively large 
forms whose posterior sigilla are situated away from the margin 
of the sternum. Such forms resemble Phlogiodes and the Thrig- 
mopoeeae in these respects. 
The spines develop only after the specimen has attained a 
moderate size; they appear in a definite order, and those which 
are normally developed last are the first to be lost in the larger 
and more highly specialized species. The complete armature may 
now be described. The spines are confined to the lower surface 
and sides of the tibiae and metatarsi. On the third and fourth 
legs they are relatively numerous in well-grown specimens of all 
species. On the first and second legs, however, they are less nu 
merous and occupy very definite positions. The metatarsi of these 
legs may bear the following spines—one midapica!l, a pair of 
lateral apicals, and one median, of which the midapical always 
appears first, the order of appearance of the others being less 
constant; but I do not know of any species in which any of these 
except the first is developed on the front leg. The complete 
armature of the tibiae consists of the following spines—inner 
apical, outer apical, and median, developed in that order. The 
tibia of the palp is similarly armed, except that so far as I know 
the median spine is never developed. 
The species of Plestophrictus in our collection are as follows :— 
Plesiophrictus satarensis, n. sp. 
(Pl. xv, figs. 3a-bd). 
Localities—Medha, 2200 ft., in the Yenna valley (7 7); 
Umbri, 3500 ft., Taloshi, 2000 ft., Helvak, 2000 ft., and Kemhsa, 
2650 ft., in the Koyna valley (@ 2 and immature). All these 
localities are in the Satara district of the Bombay Presidency. 
The upper parts of the valleys of the Yenna and Koyna, rivers 
which flow into the Krishna, are only separated by one ridge of
