The second family of the Pulmonary Arachnides, 
that of 
The Pedipalpi, 
Presents to our observation very large palpi, in the form of 
advanced arms, terminating like a pincers or talon ; forceps 
or antennse-pincers, with two fingers, one of which is mobile ; 
an abdomen composed of very distinct segments, without spin- 
nerets at the end, and the sexual organs situated at the base of 
the belly. All the body is clothed with a tolerably solid der- 
mis. The thorax is of a single piece, and presents, near the 
anterior angles, three or two simple eyes, approximated or 
grouped ; and near the middle of its anterior extremity, or pos- 
teriorly, but in the middle line, two other simple eyes, equally 
approximate. The number of the pulmonary sacs is four or 
eight.
