ACKNOWLEDGMENTS 



Through the kindness of several individuals, critical type material 

 and other valuable specimens were generously made available for 

 this study. For these loans I am indebted to K. P. Schmidt and 

 Marion Grey, of the Chicago Natural History Museum; Drs. Reeve 

 M. Bailey and W. A. Gosline, of the University of Michigan Museum 

 of Zoology; and Dr. George S. Myers and Margaret Storey, of the 

 Natural History Museum of Stanford University. Dr. Bailey further 

 assisted by donating a much-needed series of topotypes of Signalosa 

 petenensis and specimens of Dorosoma anale and D. smithi. Henry 

 W. Fowler forwarded information on the northward occurrence of 

 D. cepedianum on the Atlantic slope, and Dr. E. C. Raney sent on the 

 valid published records of this species in New York. To all these 

 workers I express my sincere thanlvs.
