more spacious, in the form of a corslet. An abdomen very 

 distinct and anniilated ; palpi very large, in the form of feet 

 or claws ; eight feet in both sexes, with two equal hooks at 

 the end of the tarsi, the anterior two, at most, excepted ; two 

 antennae -pincers or forceps apparent, terminated by two claws, 

 and two jaws formed by the first articulation of the palpi. 

 They are all terrestrial, and have the body oval or oblong. 

 This family comprehends but two genera.

Have two very large forceps, with vertical claws, strongly 

 denticulated, one upper, fixed, and often provided at its base 

 with a slender elongated appendage, terminating in a point, 

 and the others mobile ; the palpi large, advanced in the form 

 of feet, or antennse, terminated by a short articulation, in the 

 form of a button, vesicular, and without a hook at the end. 

 The two anterior feet are of a figure almost similar, equally 

 devoid of hooks, but smaller; the others are terminated by a 

 tarsus, the last articulation of wdiich is provided at the end 

 w'ith two small cushions, and two long claws, with a hook at 

 their extremity. There are five scales in the form of a half- 

 funnel, and pedicled, on each of the hinder feet, disposed in a 

 range along their first articulations ; and two eyes, very much 

 approximated on an anterior eminence of the first thoracic seg- 

 ment, which represents a large head, bearing, besides the 

 parts of the mouth, the two anterior feet. 



Their body is oblong, generally soft, and provided with 

 long hairs. The last articulation of the palpi, or their button, 

 encloses, according to M. Dufour, an especial organ, in the 

 form of a disk, of a mother-of-pearl white, and W'hich never 

 presents itself externally, but when the animal is irritated. 

 The two anterior feet may be considered as second palpi. 

 The labrum has the form of a very small and compressed 

 beak, curved, pointed, and hairy at the end. The tongue is
