About this book
The Appendages, Anatomy, and Relationships of Trilobites is by Percy E. Raymond, Ph.D. The book is dedicated to the memory of Charles Emerson Beecher, skillful with hand, brain, and pen. The list of figures includes, among others, a restoration of the ventral surface of Triarthrus becki Green and a slice of Ceraurus pleurexanthemus Green showing an exopodite.
A section is headed The Panderian Organs: Internal Gills or Poison Glands? The text says that Volborth (1857) announced that Doctor Pander had two years before discovered certain organs on the lower side of the doublure of the pleural lobes of the thorax of a specimen of Asaphus expansus. The text says that on the dorsal side specimen 235 shows portions of three exopodites which lie in a direction roughly parallel to the outer portions of the endopodites on the lower side.
