1914] Daniel: The Anatomy of Heterodontus francisci 163 



In conclusion I should like to express my appreciation of the 

 opportunity which has been afforded me as Special Investigator on 

 Elasmobranch Fishes at the Scripps Institution of the University of 

 California. To Professor Ritter, Director of that institution, I give 

 my thanks for his generous supply of valuable material upon which 

 my studies have been made.
