REVISION OF CARCHARHINID SHARK GENERA — SPRINGER 561 



All the species treated herein, with the possible exceptions of 

 Rhizoprionodon terraenovae and R. taylori, are used commonly as food, 

 and one, Scoliodon laticaudus, is considered a delicacy. The two ex- 

 ceptions noted should be edible also, but they have received little 

 attention as food, possibly because of local prejudices in the areas 

 where they occur.

During the course of this study, I was afforded the opportunity 

 of examining and radiographing specimens from the collections of a 

 large number of American and foreign institutions; I was also fur- 

 nished radiographs and data on several specimens I did not see. 



To my colleagues, I wish to express my gratitude for their generous 

 aid and extreme patience: D. E. Rosen (AMNH); G. P Whitley
