Our Common Insects |Alpheus Spring Packard
In x-notata (fig. 435) the palpus is as long as the cephalothorax, and the tarsus and palpal organ small and round.

The Common Spiders of the United States |James Henry Emerton
The palpus, too, on this side was turned back to correspond to the direction of the legs nearest it.

Near the root or base of the mandibles on each side is a jointed feeler, or palpus; but spiders have no antenn.

In montana (fig. 435a) the palpus is still shorter, the tibia thicker, and the tarsus and palpal organ larger.
