Near the root or base of the mandibles on each side is a jointed feeler, or palpus; but spiders have no antenn.
The mouth-parts in this genus are much as in Tomocerus, the maxillæ ending in a lacinia and palpus.
In x-notata (fig. 435) the palpus is as long as the cephalothorax, and the tarsus and palpal organ small and round.
Each maxilla bears a slender feeler or palpus composed of five segments.
The palpus, too, on this side was turned back to correspond to the direction of the legs nearest it.
When you touch him, he draws up slowly one leg after another, or moves a palpus feebly.
(d.) palpus, close to the upper segment of the pedicel of first cirrus.
In montana (fig. 435a) the palpus is still shorter, the tibia thicker, and the tarsus and palpal organ larger.
The palpus of the male (fig. 339) has large and complicated appendages at the end.
