tropical Africa, Madagascar, and Australia. The sternum is Table- 
pentagonal, as in the Pandinidae, but is variable in form, being ^g Se | 0 Nos ' 
sometimes much wider than long, sometimes as long as wide. 
The presence of two pedal spurs upon the feet furnishes the best 
character for distinguishing the Vejovidae from the Pandinidae. 
(Genera : Vejovis, lurus, Euscorjjius , Broteas, etc.). 
Pam. 4. — Buthidae. 
The Buthidae, which are universally distributed to the South 
of about the 45th parallel of North latitude, are distinguished from 
the Vejovidae by the triangular shape of the sternum and by the 
bifurcation of the anterior pedal spur. (Genera : Buthns, Cen- 
trum's, Isometrus, etc.) 
Order 2. — Pedipalpi (Whip-scorpions and their allies). 
The cephalothorax (prosoma) in these Arachnida is covered Table-case 
dorsally by a carapace, which is sometimes segmented posteriorly. No " 21 ' 
A deep constriction separates this region of the body from the 
abdomen (opisthosoma), which has eleven somites. The palps are 
of large size and are chelate or sub-chelate in form. The third 
appendage (first leg) is longer and more slender than the remain- 
ing legs, and has the terminal segment (or segments) sub-divided ; 
it is used as a feeler. There are no poison-glands in these 
animals. 
These Arachnids are inhabitants of the warmer parts of the 
globe. They are found in damp places under stones or fallen 
leaves, in the crevices of rocks, and in other similar places. 
Several fossil species have been discovered in the Carboniferous 
strata. The Pedipalpi are divided into two sub -orders. 
Sub-order I. — UBOPYGI. 
In these Pedipalpi the cephalothorax is longer than wide. The 
tarsi of the third pair of appendages are divided into eight or nine 
segments. There are two tribes. 
Tribe— UBOTBICHA. 
Uropygi in which the carapace is unsegmented and bears well- 
developed eyes.
