along their dorsal surface, the overlying integument carefully re-

The writer wishes to express her appreciation to all who have as- 

 sisted her in this work. Professor Hunter has always been most 

 kind in helping in whatever way possible. Dr. Paul B. Lawson, 

 under whose direction the work was done, has given freely of his 

 time and experience. Kathleen Doering, Philip Readio and Robert 

 Guntert are also deserving of thanks for their interest and assist- 

 ance.
