moveable hook. Their ligula is elongated, very narrow, and con- 
cealed. They have but two jaws, which are formed by the first joint 
of their palpi. 
They all have eight eyes, of which three, on each side and near 
the anterior angles, form a triangle ; and two near the middle at the 
anterior margin are placed on a comman tubercle or little elevation, 
one on each side. The palpi are spinous. The tarsi of the two 
anterior legs differ from the others, being formed of numerous seta- 
ceous or filiform joints, and without a terminal tail. 
They are confined to the hottest portions of Asia and America. 
Their habits are unknown to us. They now constitute two subge- 
nera. 
Phrynus, Oliv. 
Palpi terminating in a claw ; the body much flattened ; thorax 
broad, and almost in the form of a crescent; abdomen ecaudate, and 
the two anterior tarsi very long and slender, resembling setaceous 
antennae *. 
Thelyphonus, Lat. 
The Thelyphoni are distinguished from the preceding subgenus by 
their shorter, thicker palpi, terminated by a forceps, or by two 
united fingers ; by their long body with its oval thorax, and the 
extremity of the abdomen furnished with an articulated seta forming 
a tail. Their anterior tarsi are short, of a uniform appearance, and 
composed of few articulations f . 
The others have their abdomen intimately united to the thorax 
throughout its entire width, presenting, at its inferior base, two 
moveable pectiniform laminae, and terminated by a knotted tail armed 
with a terminal sting. Their stigmata, eight in number, are exposed 
and arranged four by four along the belly ; their chelicerae arc ter- 
minated by two fingers, of which the exterior is moveable. They 
form the genus 
Scorpio, Lin. Fab. 
Scorpions have an elongated body, suddenly terminated by a long 
slender tail formed of six joints, the last of which terminates in an 
arcuated and excessively acute point or sting, which affords issue to 
a venomous fluid contained in an internal reservoir, forming a long 
square, and usually marked in the middle by a longitudinal sulcus, 
presenting on each side, and near its anterior extremity, three or two
