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 MonograpJi. 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
