end. The two posterior feet are larger, with a range of small 
pedicellated scales under the haunches. 
The celebrated Pallas was the first who described with consi- 
derable detail a species of this genus, the Galeodes araneoides . 
In his Spicilegia Zoologica , and in Herbst.’s Monograph of the 
Solpuga , is a full development of the characters of these 
arachnids. Sonnini’s Voyage into Greece also contains some 
valuable information on this subject, and more particularly some 
good figures, drawn by Marechal, painter to the Museum of 
Natural History in Paris. Olivier has published a notice of 
those species which he observed in his travels in the Levant. 
The Galeodes, as we have observed, have an oblong body, 
generally covered with a skin of a weak consistence, or 
slightly scaly, brown or yellowish, often bristling with long 
hairs, some of which, belonging to the mandibles, very dis- 
tinctly appear to be tubular. The anterior part of the body 
presents two enormous mandibles, of a form pretty nearly 
conical, contiguous to each other all along their internal side, 
and terminating in a point. Each mandible is armed at its 
extremity with two talons, or scaly teeth, vertical, crossed one 
upon the other, denticulated internally, and finishing in a 
hooked point. In some species, or rather, perhaps, in the 
individuals of different sexes, a small scaly appendage is 
remarked, brown, and almost filiform, on the upper part of 
each mandible, and inclining against the posterior part. This 
appendage originates from the base of the interval between 
the hooks. Its use is unknown. 
The palpi are very large in this genus: they exceed the 
feet in bulk, and are longer than the two or three anterior 
pair; they are advanced, filiform, of six articulations, the 
radical one of which is prolonged into a point at its internal 
and superior angle, and cemented with the corresponding 
articulation of the two following feet, to form a jaw. The 
second is very short, the three following very long, and the
