sixth very short, rounded at the end, appearing to be closed 

 by a membrane, and without a hook. The two anterior feet, 

 united with the palpi at their origin, and similarly annexed to 

 the anterior segment of the body, which forms the major part 

 of the thorax, resemble them in the form, the direction, and 

 the manner in which they terminate ; but they are shorter, 

 and particularly much more slender. Their haunches pre- 

 sent an additional articulation, and which appears to be formed 

 by a division of the lower part of the third, or of the first of 

 the elongated articulations, that which corresponds to the 

 thigh. Analogy does not permit us to doubt that these organs 

 represent the two anterior feet of the other arachnida ; but 

 from the nature of their functions we may conclude with M. 

 Walckenaer, that the galeodes have four palpi, or rather six 

 palpated feet ; they approximate in this respect to Phryne 

 and Thelyphone. The jaws are separated only by a linear 

 cleft, and are even confounded together at their internal and 

 superior angle. This angle is dilated in front, and forms, in 

 the interval of the mandibles, at their origin, a small bifid 

 ligula, and terminated by two silky appendages. It conceals 

 a scaly piece, likewise ligulate, and having at the superior 

 end a claw or tooth, arched towards its base, and in the form 

 of a scythe. The two mandibles are very large, ovoid, com- 

 pressed, applied one against the other by their internal faces, 

 entirely uncovered, and advancing straight forward ; they are 

 terminated by two very strong teeth, scaly, vertical, crossed 

 at their point, and denticulated at their internal side. One 

 might suppose that these arachnida had four jaws. These 

 mandibles, the first segment of the thorax, which is much 

 more extended than the following, and its accessory parts, 

 present, united, the appearance of an enormous head. This 

 segment, or rather its dorsal plate, has the figure of a triangle, 

 whose base is a little curved from the anterior edge of the 

 corslet. We see near its middle, a small elevation, having on
