Supplementary Reading 



In addition to the suggestions in Chapter 9, Parker and Haswell, A Text-Book of 

 Zoology, volume 1, and Borradaile, Easthani, Potts, and Saunders. The Invertebrata, con- 

 tain excellent descriptions of the various phyla and numerous brief discussions of their 

 relationships. Schrock and Twenhofel, Prmciples of Invertebrate Paleontology, not only 

 summarize the fossil record for all of the groups but also offer a surprising amount of in- 

 formation on functional anatomy and embr)ology.
