Excerpt from Observations on the Pedipalpi of North AmericaIn the Phrynidae posterior to the maxillae is a corneous styloid process - we think that this represents the ligula, although apparently articulated to the sternum. For the mentum is probably in this family coalesced with, and forming the anterior por tion of the sternum. In the Scorpionidas two large processes Spring from the base of the anterior pair of feet. These form the posterior boundary of the mouth and seem to be the mentum. Two similar plates arise from the second pair of feet, these we take to be analogous with the gula. In the Thelyphonidae these are all consolidated into a single plate.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
