long as they are broad, and of about equal length, the second joint being 
somewhat conically terminated. This second joint on the underside exhibits. 
a row of (about 6) unusually long and stout spinning-tubes, about rh 
as the medium diameter of the joint, and terminating with a short. 0 
cylindrical, truncated spinning-bristle. A similar large spinning-tube is si- _ 
tuated just under the extremity of the first joint. Moreover the end of that 
joint and the whole underside of the 2”! joint are occupied by a number 
of shorter and much finer spinning-tubes, which also terminate in a Some; 
what short, fine spinning-bristle. At the apex of the spinner a few spinning-- 
tubes of different sizes are observable. The inferior spinn 
as the superior, but scarcely half as long, somewhat tapering; their second 
joint is extremely short, the apex thickly covered with small spinning-tubes ’). - 
The intermediate spinners are somewhat shorter, and of much less diameter - 
than the inferior, cylindrical, with a few spinning-tubes at the apex. pj "

The superior tarsal claws are rather weak, but large, of unifor 
curvature, with about 10 or. Je d^ ABA UM) inereasing in 
length towards the extremity of the claw; the uttermost teeth are somewhat 
sinuated (i. e. curved a little in the form of an ») and divergent; the in- 
ferior claw is small, and has only one rather coarse and somewhat curved 
tooth. Thelßelaw-joint is plainly visible, a little slenderer than the tarsus, 
rather longer than it is broad. Inside ite joint, in my specimen (a © jun.) 
lies a new outfit of claws, ready to take the place of the old ones, which. 
fall away when the spider changes its integument. . This cingumstatiog Te 
have also noticed in younger specimens of species destitute of a separate Ms 
claw-joint, e. g. in an Alistopona, and it would seem therefore to be a ge- 
neral law, that previous to every moult new claws are formed within the tar- 
sus itself. OHLERIS’ conjecture, that the old claws are retained, and only 
ers are as thick =

their skin changed ?), is not reconcileable with these observations, and must 4 
accordingly be considered as erroneous. 
In Hersiliola oraniensis (and perhaps in other species of the same 
family) it is a remarkable fact, that the palpus also of the male is armed 
with a pectinated claw. This is at least the case in the © jun. of this spe- 
cies in my possession. Only one similar case was previously known, that 
namely of Dolomedes fimbriatus, in which OHLERT has observed a pectinated 
claw at the extremity of the males as well as the female’s palpus ©). 
1) These tubes are cylindrical, narrow, and apparently destitute of a spinning 
bristle at the tip (?).
